On July 13, a broad mid-tropospheric trough of low pressure over the southeastern United States helped to initiate an area of atmospheric convection over the lower Mississippi River Valley. [1] The area of convection moved southwards and appeared to contribute to the formation of a weak and isolated surface low pressure area in the Gulf of Mexico near the coast of Louisiana during the next day. [2] Over the next couple of days, the systems circulation gradually expanded, however, surface winds remained weak and convection over the system did not persist or become well organized. [1]

On July 16, deep convection increased and organized near the center, and oil rigs and surface buoys reported surface winds of 30 mph (45 km/h). Based on the observations, it is estimated the system developed into Tropical Depression Four on July 16 while located about 150 mi (240 km) south of the southwestern Louisiana coastline.

The depression slowly organized for the next day, as it drifted to the northeast. On July 17, the rate of organization and development of deep convection increased considerably, and the depression strengthened into Tropical Storm Danny later that day. From the night of July 17 through July 18, Danny quickly developed deep convection and banding features in the favorable environment of the Gulf of Mexico, and reached hurricane status later on July 18. Located between two high pressure systems, Danny continued its unusual July track to the northeast, and crossed over southeastern Louisiana near the Mississippi River Delta. A small storm, Danny continued to strengthen after reaching the coastal waters off Mississippi on the night of July 18, and attained a peak of 80 mph (130 km/h) early on July 19. The hurricane-force winds, however, were confined to the eyewall. After stalling near the mouth of Mobile Bay on July 19, Hurricane Danny turned to the east, and made its final landfall near Mullet Point, Alabama later that day. [2]

The storm rapidly weakened as it continued northward, and degenerated into a tropical depression by July 20. The weak depression moved through Alabama, Georgia, South Carolina, and North Carolina, maintaining a well-defined cloud signature. [2] Due to a front behind the system, Danny unusually strengthened to a tropical storm over North Carolina on July 24. This rare phenomenon occurred due to interaction with a developing trough and its associated baroclinic zone. [2] [3] Danny entered the Atlantic Ocean, north of the North Carolina-Virginia border, near Virginia Beach. It quickly reached a secondary peak of 60 miles per hour (100 km/h), and continued rapidly northeastward towards the waters of the Atlantic. A strong mid to upper-level cyclone turned Danny northward, threatening Massachusetts. It stalled while just 30 miles (50 km) southeast of Nantucket on July 26, turned to the east out to sea, and became extratropical later that day. On July 27, the former hurricane merged with a frontal zone. [2]

Preparations

The National Hurricane Center issued a hurricane watch on July 17, as Danny strengthened to a tropical storm, for the coasts of Louisiana, Mississippi, and Alabama. When Danny strengthened to a hurricane on July 18, a few hours before its landfall in far southeastern Louisiana and over a day before landfall in Alabama, the hurricane watch was upgraded to a hurricane warning. [2] Grand Isle mayor Arthur Ballenger ordered the evacuation of the town's 1,500 residents, a decision made due to the large number of tourists on the island and to prevent anyone from being unable to leave the island. With a 5-foot (1.5 m) storm surge possibility, Danny had the potential to flood the only highway out of the island. Officials distributed sandbags to residents in St. Bernard Parish to seal off easily flooded roads, with officials recommending that residents leave the area. [4]

Prior to the arrival of the hurricane, the governors of Mississippi and Alabama declared disaster emergencies, expecting a 9-foot (2.7 m) storm surge and up to 20 inches (500 mm) of rain at that time. Six shelters were opened in Mobile County, Alabama, though few utilized them. Officials also considered opening shelters near local casinos and beaches in Biloxi, Mississippi. [5] Alabama Governor Fob James also activated the state's National Guard ahead of the storm and directed 30,000 sandbags to the Alabama coast for protection. [6]

Southeastern Massachusetts also had a tropical storm warning issued, a few hours before sustained tropical storm force winds affected the area and less than 12 hours before its closest approach to the coastline. [2]

Impact

Rainfall totals from Hurricane Danny

As a small storm, Hurricane Danny only caused a damage toll of $100 million (1997  USD, $182 million2024 USD). A total of 4 direct and 5 indirect deaths resulted from the effects of Danny. [2]

Gulf Coast

Heavy rain and winds buffeted many parishes located east of the city of New Orleans. [2] [5] A small radius near the center of the storm had much of the extreme rainfall, and limited the flooding, which could have been disastrous if it were widespread. [2] [7] Grand Isle and portions of the lower Plaquemines Parish were the worst hit in Louisiana. Additionally, Grand Isle reported a wind gust of 100 mph (160 km/h) and a storm surge of 5.2 feet (1.6 m). [7] At New Orleans International Airport, sustained winds of 28 mph (45 km/h) and gusts of 33 mph (53 km/h) were reported on July 19. [8] A gauge reported a water level of 4.85 feet (1.48 m) in Venice. Storm tides were 2 to 3 feet (0.61 to 0.91 meters) above normal on average. [7]

At least 10,000 people lost electricity in Louisiana. Furthermore, 130 boats were damaged or sunk at a large marina in Buras, Louisiana, due to the storm surge of over 4 feet (1.2 m), in a matter of minutes. [5] Both Grand Isle and Grand Terre Island received erosion on their shores, while many commercial fishing boats in Grand Isle were also heavily damaged. [9] [10] Around 160 households and 80 businesses reported damage on Grand Isle. Jefferson Parish and Plaquemines Parish had $1.5 million (1997 USD$, 2.73 million2024 USD) and $3.5 million (1997 USD$, 6.38 million2024 USD) total in damage respectively. [7] Significant flooding happened throughout Jefferson Parish, with the floods affecting a total of 163 houses and 84 businesses. Meanwhile, in Plaquemines Parish, ten houses and 35 trailers had damage, with 8 businesses at least partially flooded and 40 commercial fishing boats also damaged. Lafourche Parish had no significant damage to report. [8] Empire and Venice were the most damaged areas in Plaquemines Parish. In the areas of Plaquemines Parish within the hurricane protection levees, trees, power lines, house roofs, and mobile homes sustained damage, in addition to localized flooding throughout the parish after about 10 inches of rain. In lower Terrebonne Parish, some highways were flooded, due to storm tides, and a few roads were also flooded in St. Bernard and Orleans parishes, which were outside the hurricane protection levees. Negligible damage occurred elsewhere in the extreme southeastern portion of Louisiana, due to Danny being a small tropical cyclone and a minimal hurricane. [7]

Eastern Jackson County had the greatest impact throughout Mississippi. Pascagoula reported a wind gust of 35 mph (56 km/h) on July 19. Pascagoula airport reported 7.87 inches (200 mm) of rain from July 17 through July 19. Some streets and a few homes were flooded in far southeastern Jackson County, in areas of poor drainage systems. The coast of Mississippi had no significant damage according to emergency management officials. [11] An oil rig off the coast of Pascagoula was ripped from its moorings and collided with a tank that spilled 500 gallons (1,892 L) of fuel into the Bayou Casotte stream. [12]

By late on July 19, the American Red Cross was providing shelter to over 2,000 people in Alabama, Mississippi, and Florida. [13]

Extreme amounts of rainfall were produced over Alabama. [2] Dauphin Island had the highest amount of rainfall, 37.75 in (959 mm) reported by the HPC. [14] Dauphin Island Sea Lab recorded 36.71 in (932 mm) of rain, but not all the rain may have recorded in the rain gauge at this location, so it is possible the rainfall may have been underestimated. Doppler weather radar estimates show that around 43 inches (1,100 mm) of rain fell off the coast of Dauphin Island. A storm surge of over 6.5 feet (2.0 m) occurred off Highway 182, midway between Gulf Shores and Fort Morgan, in addition to the rainfall. Unusually, when the storm stalled off the coast of Alabama, prevailing northerly winds forced the water out of Mobile Bay, causing tides to be two feet (0.61 m) below normal. Observers noted that, if river channels had not remained, it would have been possible to walk across the bay unhindered by water. [2] Additionally, a four-story condominium project that was under construction in Gulf Shores crashed due to high winds. [15] In addition, three tornadoes occurred in Alabama, destroying a marina just south of Orange Beach and damaging several of the boats; Opelika, where damage was minimal; and Alabama Port respectively. [2] [16]

Despite its effects in the northern Gulf of Mexico, only one person was directly killed from the storm there; a man drowned off the coast when he fell off his sailboat near Fort Morgan, Alabama. One indirect casualty also occurred in the area, when a man had a heart attack while trying to secure a boat off the Alabama coast during the storm. [2] Numerous roads became flooded and impassable for several days, south and along I-10 in Mobile, south and central Choctaw, and Baldwin counties. Along the Fowl and Fish rivers, in Mobile and Baldwin counties respectively, significant damage to homes occurred due to flooding. Most roads on Dauphin Island were flooded in over a foot of water. A few homes were close to falling into Mobile Bay, and one home had to be moved backwards towards land to prevent its destruction. [17] At the peak of the storm in Alabama, at least 44,000 people were without power in Mobile and Baldwin counties. In rural Choctaw County, north of Mobile, several families were rescued from flooded roads and trapped cars. [9] The majority of houses and businesses on Dauphin Island and buildings from the western shore of Mobile Bay, and from Fort Morgan east to Orange Beach, had roof damage$. 60.5 million (1997 USD$, 110 million2024 USD) in total property damage occurred in Alabama, in addition to pecan and pine tree damage costing $2.5 million (1997 USD$, 4.56 million2024 USD). [17]

In the state of Florida, some damage to the cotton crop occurred in Escambia County. Otherwise, very little damage resulted from the storm in northwestern Florida. [17] The Panama City, Florida area had some minor fresh water flooding. [8] A race in the NASCAR All Pro series at the Five Flags Speedway in Pensacola, Florida scheduled to be held on July 19 was postponed to September 13, 1997, due to Hurricane Danny. [18] By the time Danny reached Georgia and the Carolinas, its potential impact had weakened, though it still managed to produce 8–12 inches (200–300 mm) of rain as it drifted through the western portions of the states. [2] In Augusta, Georgia, fourteen South Carolina National Guardsmen were struck by lightning, one of whom had to be hospitalized in intensive care and six others received treatment at a hospital and were then released. [19] Four indirect deaths occurred from traffic accidents during the storm's onslaught in Georgia. [2] Seven tornadoes and one waterspout resulted in South Carolina due to Danny strengthening over the southern Appalachians. [20] Among those tornadoes, a severe thunderstorm cell in South Carolina produced five tornadoes which touched down, one of which killed a woman in her destroyed duplex while passing through Lexington County. [2] Additionally, a F2 tornado with a width of 200 yards (200 m) and a length of 4 miles (6 km), was on the ground for 3 miles (5 km) to the northeast of Gaston, South Carolina, causing $942,000 (1997 USD$, 1.72 million2024 USD) in damage, killing one, injuring six, and destroying 13 residences, with damage to many others. [21] Several tornadoes and waterspouts were spawned over Virginia; most of them occurred in Norfolk, Portsmouth, and Hampton. [22] An F1 tornado with a width of 50 yards (50 m) and a length of 1-mile (1.6 km), touched down 1-mile (1.6 km) in Portsmouth, causing $400,000 (1997 USD$, 729,1872024 USD) in damage. It destroyed a car wash and damaged 7 other structures, all but 1 of which were businesses, and also flipped over a semi-trailer truck. [23] Rainfall in Fayetteville measured 2.85 inches (72 mm), while the remainder of the Mid-Atlantic states received approximately 3 inches (76 mm) of rain. [24]

The heavy rains caused two people to drown in Charlotte. A girl drowned after being swept into a creek, and a woman drowned while in her car. [2] Also in North Carolina, tropical rains related to Danny caused a CSX train to derail from its trestle into Little Sugar Creek, spilling about 2,500 gallons (9,500 L) of diesel and therefore forcing a nearby public housing development to be evacuated. [25] After Danny emerged over the Atlantic Ocean on the North Carolina-Virginia border and restrengthened into a tropical storm on July 25, wind and rain started as far north as New York and New England. [26] Sustained tropical-storm force winds affected Martha's Vineyard, Nantucket Island, and parts of Cape Cod, in addition to the coastal waters from the entrance of Buzzards Bay to the south and east of Cape Cod. Only minor damage occurred, despite these strong winds, which were experienced primarily in southeastern Massachusetts. [8] [27] The minor damage included localized flooding, power outages, downed tree limbs, and lost boats. A suspension of ferry service to Nantucket Island occurred for most of July 25, with a shorter suspension happening on the service to Martha's Vineyard. No significant coastal flooding affected the region, although a storm shelter was opened on Nantucket Island to host a Boy Scout group camping there. Danny was the fifth tropical cyclone to affect Southern New England in the 20th century during the month of July. [8]

On July 24, the U.S. House of Representatives considered House Amendment 271 to H.R. 2160 Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 1998, to eliminate federal support for crop insurance for tobacco farmers and disaster assistance provided to non-insured crops of tobacco. During debate of the amendment, Congressman Etheridge (D-NC) stated that one of the reasons he opposed it was due to the harm it would cause to farmers like those in his home state of North Carolina whose tobacco crops were being flooded by Danny. Other congressmen from his state including Richard Burr and Walter B. Jones Jr. also opposed it. [28] Ultimately, the vote on the amendment failed by a vote of 209 to 216 and it failed to be included in the bill that later became law. [29]

On July 25, President Clinton declared a major disaster in Alabama in the aftermath of Hurricane Danny. He ordered that federal aid be provided in assistance to state and local efforts to respond in the areas of Alabama impacted by wind and flooding damage. [30]

Debris remained in the inland waters of Alabama until at least August 12, 1997. Endangered or threatened sea turtles lived in these waters and were threatened by the debris. Specialized turtle exclusion devices, known as TEDs, or specialized nets that allowed the turtles to escape them, were required before Danny for shrimp trawlers. The Director of the Marine Resources Division of the Alabama Department of Conservation and Natural Resources said that the "inordinate amount of debris is causing extraordinary difficulty with the performance of (TEDs) in these areas." Therefore, the United States Environmental Protection Agency allowed an alternative to the TEDs, of shorter tow times with seasonal restrictions of a maximum of 55 minutes from April 1 through October 31, and a maximum of 75 minutes from November 1 through March 31. By making the shorter tow times the required alternative, the EPA intended to minimize any sea turtle casualties as a result of trawlers being allowed to remove the TEDs. [31]

One of three wolves that escaped from a zoo in Gulf Shores, Alabama during Hurricane Danny was found in November later that year, after seasonal conditions meant less tourists and therefore less food in Gulf State Park where the wolf had resided. One of the other wolves had already been recaptured, while the other had already been shot and killed. [32]

Some cotton crops in the Southeast United States received needed rainfall from Danny, while others were harmed, as 100,000 acres of cotton fields in Alabama were too heavily damaged for their crop to be salvaged. [33] The effects of Danny caused the gasoline production of Gulf Coast oil refineries to decline and thus contributed to an increase in gas prices in the months following Danny throughout the United States. [34] A severe drought had been in place in the Mid-Atlantic region during the month of July. [8] The high amount of rainfall caused by Danny helped to ease dry conditions in portions of the Mid-Atlantic, but not sufficiently to stop the drought from developing further in most areas from northern Virginia to southern New England. [35]

A study published in Social Behavior and Personality in 1998 surveyed respondents from the University of West Florida and businesses in Pensacola for the news media sources they relied on during Hurricane Danny. Overall, the frequency of usage from highest to lowest among respondents was local TV stations, the cable network Weather Channel, local FM radio stations, cable news stations, and followed by other sources. [36]

The extremely short distance of the eyewall of Hurricane Danny from a Doppler weather radar station in Mobile, Alabama and its slow landfall over the course of a day led to further study by meteorologists. The proximity to land allowed for measurements at a level closer to the surface than it is possible for hurricane reconnaissance aircraft to achieve, with the slow landfall allowing for more extended observation. One conclusion of the study, published in 2000, included the need to sample the boundaries of an eyewall more to establish a better estimate of surface-level winds and the overall intensity of a storm. Another conclusion was that while Danny's slow movement positioned it over a tidal estuary bordering the Gulf, maintaining of or increase in strength was possible since eyewall convection remained over waters with high sea surface temperatures and other environmental conditions remained favorable. [37]

The storm dropped 36.71 in (932 mm) of rain on Dauphin Island, setting the new record for the most tropical or subtropical cyclone related rainfall in the state of Alabama, and is among the largest in the United States. [2]

Hurricane Hilda was an intense tropical cyclone that ravaged areas of the United States Gulf Coast, particularly Louisiana. In addition to its damage inland, the hurricane greatly disrupted offshore oil production, and at its time was the costliest tropical cyclone for Louisiana's offshore oil production. Due in part to flights made by the National Hurricane Research Laboratory, Hilda became one of the most well-documented storms meteorologically in the Atlantic. Lasting for seven days as a tropical cyclone, Hilda caused US$126 million in damage and 38 deaths. It was the tenth named storm, sixth hurricane, and the fourth major hurricane of the 1964 Atlantic hurricane season.

<span class="mw-page-title-main">Hurricane Ethel (1960)</span> Category 3 Atlantic hurricane in 1960

Hurricane Ethel was one of two major hurricanes in the 1960 Atlantic hurricane season. The sixth known tropical cyclone, fifth named storm, and fourth hurricane of the season, Ethel developed from a disturbance in the Gulf of Mexico on September 14. After becoming a tropical storm, Ethel rapidly intensified and became a hurricane six hours later. By early on September 15, the storm reached major hurricane intensity when it became a Category 3 hurricane on the Saffir–Simpson hurricane scale. However, shortly thereafter, Ethel rapidly weakened back to a Category 1 hurricane while brushing eastern Louisiana. Later on September 15, Ethel weakened to a tropical storm. Early on the following day, Ethel made landfall in Pascagoula, Mississippi. The storm gradually weakened inland, before eventually dissipating over southern Kentucky on September 17.

<span class="mw-page-title-main">Hurricane Juan (1985)</span> Category 1 Atlantic hurricane in 1985

Hurricane Juan was a large and erratic tropical cyclone that looped twice near the Louisiana coast, causing widespread flooding. It was the tenth named storm of the 1985 Atlantic hurricane season, forming in the central Gulf of Mexico in late October. Juan moved northward after its formation, and was subtropical in nature with its large size. On October 27, the storm became a hurricane, reaching maximum sustained winds of 85 mph (140 km/h). Due to the influence of an upper-level low, Juan looped just off southern Louisiana before making landfall near Morgan City on October 29. Weakening to tropical storm status over land, Juan turned back to the southeast over open waters, crossing the Mississippi River Delta. After turning to the northeast, the storm made its final landfall just west of Pensacola, Florida, late on October 31. Juan continued quickly to the north and was absorbed by an approaching cold front, although its moisture contributed to a deadly flood event in the Mid-Atlantic states.

<span class="mw-page-title-main">Tropical Storm Matthew (2004)</span> Atlantic tropical storm in 2004

Tropical Storm Matthew was a weak tropical storm in the 2004 Atlantic hurricane season that made landfall on Louisiana. It was the thirteenth tropical storm of the season and the ninth to affect the United States. It formed over the western Gulf of Mexico on October 8 and struck south-central Louisiana two days later. The combination of the storm and an upper cyclone over the southern Plains brought heavy rains to much of the Gulf Coast, with the highest amounts reported over 15 inches (380 mm) in northern Louisiana. Damage was minimal, totaling $305,000 (2004 USD), and no casualties were reported.

<span class="mw-page-title-main">Hurricane Danny (1985)</span> Category 1 Atlantic hurricane in 1985

Hurricane Danny produced 13 significant (F2+) tornadoes in the Southern United States during August 1985, the most spawned by a tropical cyclone until Hurricane Ivan in 2004. The fourth named storm and third hurricane of the season, Danny developed from a tropical wave in the northwestern Caribbean Sea on August 12. The system moved northwestward and initially remained weak. Early on August 13, it brushed Cape San Antonio, Cuba before emerging the Gulf of Mexico later that day. The system then intensified into Tropical Storm Danny on August 14. Danny deepened further and became a hurricane early on the following day, while beginning to re-curve north-northwestward. Late on August 16, Danny attained its peak intensity with winds of 90 mph (150 km/h). Shortly thereafter, the storm made landfall near Grand Chenier, Louisiana at the same intensity. Early on August 17, Danny weakened to a tropical storm and was downgraded to a tropical depression several hours later. It moved east-northeastward across the Southeastern United States, until dissipating over southeastern Virginia on August 18.

<span class="mw-page-title-main">Tropical Storm Hanna (2002)</span> Atlantic tropical cyclone

Tropical Storm Hanna was a moderately strong tropical storm that affected the Gulf Coast and Southeastern regions of the United States. The ninth tropical cyclone and eighth named storm of the 2002 Atlantic hurricane season, Hanna formed through the complex interaction of a surface trough, a tropical wave, and an upper-level low pressure system, a disturbance in the upper atmosphere. Designated a tropical depression at 0000 UTC on September 12, the storm remained disorganized throughout its duration, though it attained tropical storm status and a peak intensity of 1,001 mbar (29.6 inHg), with winds of 60 miles per hour (100 km/h). Hanna crossed extreme southeastern Louisiana, and made a second landfall along the Alabama–Mississippi border.

<span class="mw-page-title-main">Tropical Storm Bill (2003)</span> Atlantic tropical cyclone

Tropical Storm Bill was a tropical storm that affected the Gulf Coast of the United States in the summer of 2003. The second storm of the 2003 Atlantic hurricane season, Bill developed from a tropical wave on June 29 to the north of the Yucatán Peninsula. It slowly organized as it moved northward, and reached a peak of 60 miles per hour (97 km/h) shortly before making landfall in south-central Louisiana. Bill quickly weakened over land, and as it accelerated to the northeast, moisture from the storm, combined with cold air from an approaching cold front, produced an outbreak of 34 tornadoes. Bill became extratropical on July 2, and was absorbed by the cold front later that day.

<span class="mw-page-title-main">Tropical Storm Barry (2001)</span> Atlantic tropical cyclone

Tropical Storm Barry was a strong tropical storm that made landfall on the Florida Panhandle during August 2001. The third tropical cyclone and second named storm of the 2001 Atlantic hurricane season, Barry developed from a tropical wave that moved off the coast of Africa on July 24. The wave entered the Caribbean on July 29 and spawned a low-pressure area, which organized into Tropical Storm Barry on August 3. After fluctuations in intensity and track, the storm attained peak winds of 70 mph (110 km/h) over the Gulf of Mexico. Barry headed northward and moved ashore along the Gulf Coast before degenerating into a remnant low on August 7. On the next day, Barry's remnants dissipated over Missouri.

<span class="mw-page-title-main">Tropical Storm Bertha (2002)</span> Atlantic tropical storm in 2002

Tropical Storm Bertha was a minimal tropical storm that made landfall twice along the Gulf Coast of the United States in August 2002. The second tropical storm of the 2002 Atlantic hurricane season, Bertha developed in the northern Gulf of Mexico out of a trough of low pressure that extended into the Atlantic on August 4. It quickly organized and reached tropical storm strength before making landfall on southeastern Louisiana. Bertha turned to the southwest over the state, and re-entered the Gulf of Mexico on August 7. It remained disorganized due to proximity to land, and after making landfall on south Texas, Bertha dissipated on August 9.

<span class="mw-page-title-main">1987 Gulf Coast tropical storm</span> Atlantic tropical storm in 1987

The 1987 Gulf Coast tropical storm caused flooding along the Gulf Coast of the United States. The second tropical cyclone and first tropical storm of the 1987 Atlantic hurricane season, it originated from a tropical wave in the Gulf of Mexico, southeast of Texas, on August 9. Initially a tropical depression, the cyclone moved north-northwestward and slightly intensified into a tropical storm later that day. By August 10, it made landfall between Galveston and Beaumont. The system weakened after moving inland and turned towards the east and later southeast. Briefly reemerging over the Gulf on August 15, the depression moved onshore a second time in Florida, before dissipating over eastern Georgia on August 17.

<span class="mw-page-title-main">Hurricane Florence (1988)</span> Category 1 Atlantic hurricane in 1988

Hurricane Florence was the third of four named tropical cyclones to make landfall on the United States during the 1988 Atlantic hurricane season. The seventh tropical storm and second hurricane of the season, Florence developed on September 7 from an area of convection associated with a dissipating frontal trough in the southern Gulf of Mexico. After initially moving eastward, the storm turned northward and strengthened. Florence reached hurricane status and later peak winds of 80 mph (130 km/h) on September 9 shortly before striking southeastern Louisiana. The storm rapidly weakened over land and dissipated on September 11 over northeastern Texas.

<span class="mw-page-title-main">Tropical Storm Chris (1982)</span> Atlantic tropical storm in 1982

Tropical Storm Chris caused minor flooding along the Gulf Coast of the United States in September 1982. The fifth tropical or subtropical cyclone and third named storm of the 1982 Atlantic hurricane season, Chris developed from a surface low-pressure area in the northern Gulf of Mexico on September 9. Although initially displaying subtropical characteristics, the low pressure area gradually acquired tropical characteristics, and was reclassified as Tropical Depression Four within 24 hours of development. The depression then began to intensify and was upgraded to Tropical Storm Chris on September 10. Thereafter, the storm turned north-north-eastward and strengthened further. On September 11, Chris peaked as a 65 mph (100 km/h) tropical storm. Later that day, it made landfall near Sabine Pass, Port Arthur, Texas. By September 13, Chris dissipated over Arkansas.

<span class="mw-page-title-main">Hurricane Humberto (2007)</span> Category 1 Atlantic hurricane in 2007

Hurricane Humberto was a Category 1 hurricane that formed and intensified faster than any other North Atlantic tropical cyclone on record, before landfall. The eighth named storm and third hurricane of the 2007 Atlantic hurricane season, Humberto developed on September 12, 2007, in the northwestern Gulf of Mexico. The tropical cyclone rapidly strengthened and struck High Island, Texas, with winds of about 90 mph (140 km/h) early on September 13. It steadily weakened after moving ashore, and on September 14, Humberto began dissipating over northwestern Georgia as it interacted with an approaching cold front.

<span class="mw-page-title-main">Tropical Storm Becky (1970)</span> Atlantic tropical storm in 1970

Tropical Storm Becky was the second tropical cyclone and named storm of the 1970 Atlantic hurricane season. Becky formed from a tropical depression that was designated on July 19. The next day it organized over the Yucatán Channel and became Tropical Storm Becky. Initially thought to have attained minimal hurricane status, Becky reached peak winds of 65 mph (100 km/h), but the storm began to deteriorate shortly thereafter. The storm made landfall on the Florida Panhandle on July 22, and rapidly weakened over land. Overall, damage was related to heavy rainfall that caused flooding in Tallahassee, Florida; 104 families suffered flood-related losses. About $500,000 in damage was attributed to the storm. Further north, the heavy rainfall swelled rivers. Becky may have been partially responsible for spawning tornadoes that destroyed or damaged several houses.

<span class="mw-page-title-main">Hurricane Babe</span> Category 1 Atlantic hurricane in 1977

Hurricane Babe was the second named storm and the first to impact the United States during the inactive 1977 Atlantic hurricane season. Forming out of a tropical wave on September 3, Babe began as a subtropical cyclone in the eastern Gulf of Mexico. The storm gradually intensified as it tracked westward. On September 5, the storm turned north and acquired tropical characteristics. Later that day, Babe intensified into a hurricane and attained its peak strength with winds of 75 mph (120 km/h) and a barometric pressure of 995 mbar. Several hours later, the hurricane made landfall in Louisiana and quickly weakened. By September 6, Babe had weakened to a tropical depression and later dissipated early on September 9 over North Carolina.

<span class="mw-page-title-main">Tropical Storm Cindy (2017)</span> Atlantic tropical storm in 2017

Tropical Storm Cindy was an Atlantic hurricane which became the first tropical cyclone to make landfall in Louisiana since Hurricane Isaac in 2012. The third named storm of the extremely active 2017 Atlantic hurricane season, Cindy formed out of a broad area of low pressure that developed in the northwestern Caribbean Sea near the Yucatán Peninsula in mid-June 2017. The disturbance gradually organized as it drifted northwards into the Gulf of Mexico, and was first designated as a potential tropical cyclone by the National Hurricane Center on June 19, before organizing into a tropical storm the next day. While slowly moving to the northwest, Cindy's intensification was slow due to the effects of dry air and moderate to strong wind shear. After peaking with sustained winds of 60 mph (95 km/h) on June 21, Cindy weakened slightly prior to making landfall in southwestern Louisiana on June 22. The storm quickly weakened after moving inland and degenerated into a remnant low on June 23, dissipating over the Mid-Atlantic on the following day.

<span class="mw-page-title-main">Hurricane Barry (2019)</span> Category 1 Atlantic hurricane in 2019

Hurricane Barry was an asymmetrical Category 1 hurricane that was the wettest tropical cyclone on record in Arkansas and the fourth-wettest in Louisiana. The second tropical or subtropical storm and first hurricane of the 2019 Atlantic hurricane season, Barry originated as a mesoscale convective vortex over southwestern Kansas on July 2. The system eventually emerged into the Gulf of Mexico from the Florida Panhandle on July 10, whereupon the National Hurricane Center (NHC) designated it as a potential tropical cyclone. Early on July 11, the system developed into a tropical depression, and strengthened into a tropical storm later that day. Dry air and wind shear caused most of the convection, or thunderstorms, to be displaced south of the center. Nevertheless, Barry gradually intensified. On July 13, Barry attained its peak intensity as Category 1 hurricane with 1-minute sustained winds of 75 mph (120 km/h) and a minimum central pressure of 993 millibars (29.3 inHg). At 15:00 UTC, Barry made its first landfall at Marsh Island, and another landfall in Intracoastal City, Louisiana, both times as a Category 1 hurricane. Barry quickly weakened after landfall, falling to tropical depression status on July 15. The storm finally degenerated into a remnant low over northern Arkansas on the same day, subsequently opening up into a trough on July 16. The storm's remnants persisted for another few days, while continuing its eastward motion, before being absorbed into another frontal storm to the south of Nova Scotia on July 19.

<span class="mw-page-title-main">Hurricane Sally</span> Category 2 Atlantic hurricane in 2020

Hurricane Sally was a destructive and slow-moving Atlantic hurricane that was the first hurricane to make landfall in the U.S. state of Alabama since Ivan in 2004, coincidentally on the same date in the same place. The eighteenth named storm and seventh hurricane of the extremely active 2020 Atlantic hurricane season, Sally developed from an area of disturbed weather which was first monitored over the Bahamas on September 10. The system grew a broad area of low-pressure on September 11, and was designated as a tropical depression late that day. Early the next day, the depression made landfall at Key Biscayne and subsequently strengthened into Tropical Storm Sally that afternoon. Moderate northwesterly shear prevented significant intensification for the first two days, but convection continued to grow towards the center and Sally slowly intensified. On September 14, a center reformation into the center of the convection occurred, and data from a hurricane hunter reconnaissance aircraft showed that Sally had rapidly intensified into a strong Category 1 hurricane. However, an increase in wind shear and upwelling of colder waters halted the intensification and Sally weakened slightly on September 15 before turning slowly northeastward. Despite this increase in wind shear, it unexpectedly re-intensified, reaching Category 2 status early on September 16 before making landfall at peak intensity at 09:45 UTC on September 16, near Gulf Shores, Alabama, with maximum sustained winds of 110 mph (180 km/h) and a minimum central pressure of 965 millibars (28.5 inHg). The storm rapidly weakened after landfall before transitioning into an extratropical low at 12:00 UTC the next day. Sally's remnants lasted for another day as they moved off the coast of the Southeastern United States before being absorbed into another extratropical storm on September 18.

<span class="mw-page-title-main">Tropical Storm Claudette (2021)</span> Atlantic tropical storm in 2021

Tropical Storm Claudette was a weak tropical cyclone that caused heavy rain and tornadoes across the Southeastern United States in June 2021, leading to severe damage. The third named storm of the 2021 Atlantic hurricane season, Claudette originated from a broad trough of low pressure over the Bay of Campeche on June 12. The disturbance moved erratically over the region for the next several days, before proceeding northward with little development due to unfavorable upper-level winds and land interaction. Despite this, the National Hurricane Center (NHC) initiated advisories on it as a Potential Tropical Cyclone late on June 17, due to its imminent threat to land. The disturbance finally organized into Tropical Storm Claudette at 00:00 UTC on June 19 just before landfall in southeast Louisiana. Claudette weakened to a depression as it turned east-northeastward before moving through Mississippi, Alabama, Georgia, and South Carolina. Baroclinic forcing then caused Claudette to reintensify into a tropical storm over North Carolina early on June 21 before it accelerated into the Atlantic Ocean later that day. Soon afterward, it degenerated into a low-pressure trough on the same day, before being absorbed into another extratropical cyclone on the next day.
