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.
Upon making landfall on Louisiana, the storm produced a moderate storm surge, causing tidal flooding. In a city in the northeastern portion of the state, the surge breached a levee, which flooded many homes in the town. Moderate winds combined with wet soil knocked down trees, which then hit a few houses and power lines, and left hundreds of thousands without electric power. Two people drowned from rough surf in Florida. Further inland, tornadoes from the storm produced localized moderate damage. Throughout its path, Tropical Storm Bill caused around $50 million in damage (2003 USD) and four deaths.
A tropical wave developed scattered convection in the central Caribbean Sea on June 24, while interacting with an upper-level low. It moved slowly northwestward, 40 miles (64 km) north of Progreso, Yucatán.and remained disorganized due to strong upper level wind shear. Late on June 27, the convection became slightly better organized around a broad low pressure area, though land interaction prevented further development as it moved towards the Yucatán Peninsula. The area of low pressure became better defined over the central Yucatán Peninsula, and after the system turned to the northwest, convection quickly organized while located over the warm waters of the Gulf of Mexico. On June 29, following the development of a closed circulation, the system organized into Tropical Depression Three while located about
The depression quickly strengthened to become Tropical Storm Bill later on June 29. Operationally, the National Hurricane Center did not begin issuing advisories until it attained tropical storm status. 60 miles per hour (97 km/h), one hour before making landfall in southwestern Terrebonne Parish, Louisiana. It moved onshore at peak intensity, and quickly weakened to a depression over land as it accelerated to the northeast. Bill remained a tropical cyclone as it moved through the southeast United States, until it became attached to an approaching cold front on July 2 near the Tennessee–Virginia border. The remnant extratropical storm was absorbed by the cold front on July 3 near central Virginia, while the remnant low pressure area continued northeastward until reaching the Atlantic Ocean later on July 3.Initially, the system resembled a subtropical cyclone, with the strongest winds and deep convection located far from the center, though it was classified tropical due to its tropical origins. The storm steadily intensified as wind shear decreased, and early forecasts from the National Hurricane Center mentioned the possibility of Bill intensifying to hurricane status if the low level circulation organized beneath the area of deepest convection. Bill turned to the north-northwest, and later to the north, as it moved around the periphery of a ridge of high pressure. On June 30, Tropical Storm Bill reached a peak intensity of
Shortly after the storm formed, the National Hurricane Center issued a tropical storm watch from the southern end of Galveston Island to Morgan City, Louisiana. As a more northward motion occurred, the watch was canceled and replaced with a tropical storm warning from High Island, Texas, to Pascagoula, Mississippi. Shortly before the storm made landfall, the warning was discontinued between High Island and Cameron, Louisiana. The National Hurricane Center briefly issued a hurricane watch from Intracoastal City to Morgan City, but it was discontinued when Tropical Storm Bill failed to strengthen.Prior the storm making landfall, local National Weather Service offices issued flash flood watches and a tornado watch for large portions of the Gulf Coast.
The threat of Tropical Storm Bill caused 41 oil platforms and 11 oil rigs to evacuate. This resulted in a loss of production of over 71 thousand barrels (11,300 m3) of oil and 610 million cubic feet (17,000,000 m3) of gas.
The American Red Cross mobilized workers and brought food, water, and other supplies to Louisiana prior to the storm's arrival. At the request of Louisiana emergency management officials, the organization opened two shelters for residents in low-lying areas. Several floodgates in New Orleans were closed before the storm made landfall, and many universities and government offices were closed as well. Parishes along the coastline closed summer camps and prepared sand bags, boats, and high-wheeled vehicles.Officials declared a voluntary evacuation for Grand Isle, though few residents heeded the recommendation. Louisiana Governor Mike Foster declared a statewide state of emergency to easily make state resources available, and Mississippi Governor Ronnie Musgrove made a similar declaration for Harrison, Hancock, and Jackson Counties, where shelters were also opened. Officials in Mississippi ordered the evacuation of flood-prone areas in anticipation for a moderate storm surge and above-normal tides.
Bill caused four direct deaths along its path, as well as minor to moderate damage. Damage estimates totaled to over $50 million (2003 USD, $69.5 million2021 USD), primarily as a result of flooding or tornadic damage. Throughout its path, Bill spawned 34 tornadoes, ranking it fourteenth in the list of North Atlantic hurricanes generating the most tornadoes. The tornado outbreak was caused by wind shear, moist air from the storm, and cool air from an approaching cold front. In spite of the large numbers of tornadoes, most were weak and short-lived. Prior to forming, the storm produced rainfall along coastal areas of Mexico along the Bay of Campeche, peaking at nearly 4 inches (100 mm) in Yucatán, and over 3 inches (76 mm) in Campeche.
The outer bands of Bill dropped light rain across southeastern Texas, peaking at 1.07 inches (27 mm) in Jamaica Beach. Sustained winds from the storm remained weak, and peak wind gusts were 20 miles per hour (32 km/h) in eastern Galveston County. Upon making landfall, Bill caused a storm surge of up to 3.81 feet (1.16 m) at Pleasure Pier. Effects in Texas were minimal, limited to minor beach erosion on the Bolivar Peninsula.
A moderate storm surge accompanied Tropical Storm Bill as it made landfall on Louisiana. In the state, the maximum reported surge was 5.8 feet (1.8 m), and it occurred at the Louisiana Universities Marine Consortium facility in Chauvin. In Montegut, the surge breached a levee which was still damaged from the effects of Hurricane Lili 9 months before. The breach flooded many homes in the town, forcing the evacuation of an entire neighborhood. As a result, 150 homes in the town were damaged, with half of them severely. The storm surge affected numerous low-lying cities in southeastern Louisiana by flooding roadways, including the only road to Grand Isle, stranding residents and visitors. The road was opened a day after the storm as floodwaters receded. The floodwaters entered a few homes and businesses in St. Tammany Parish. Damage from the storm surge totaled $4.1 million (2003 USD). Rough waves sank two boats offshore; their occupants were rescued.
The tornado outbreak associated with the storm began with an F0 in St. Bernard Parish that destroyed a boat house. trailers. One trailer with a woman and three children was lifted into the air and dropped 30 feet (9.1 m) away; four occupants were injured, none of them seriously. Damage from the tornado amounted to $2 million (2003 USD, $2.78 million2021 USD). A third tornado, rated an F0, struck Orleans Parish, damaging a car and a portion of a roof.A short-lived F1 tornado touched down in Reserve, striking a private high school, where it destroyed half of one classroom and damaged several others. Later, the F1 tornado passed through a trailer park and severely damaged or destroyed 20
Winds of 35 to 45 mph (56–72 km/h) were common across southeastern Louisiana, with the highest sustained wind being 53 miles per hour (85 km/h) in Chauvin and a peak gust of 62 miles per hour (100 km/h) on the northern end of the Lake Pontchartrain Causeway. The winds knocked trees and tree branches into power lines, leaving 224,000 residents without power. The storm dropped moderate to heavy amounts of precipitation, peaking at 10.2 inches (260 mm) at a location 6 miles (9.7 km) south of Folsom. The rainfall led to flash flooding, which inundated roads and cars and overwhelmed local drainage capacities. The rainfall also led to overflown rivers and creeks, resulting in flooding along the Tangipahoa River in southern Tangipahoa Parish, and the Bogue Falaya and Tchefuncte River in St. Tammany Parish. The Bogue Falaya River crested at 57 feet (17 m) on July 1, 12 feet (3.7 m) above flood stage, which became a record for the recording station. The flooding damaged several structures and roadways. Less severe river flooding occurred in Washington and Livingston Parishes. In all, damage in Louisiana totaled to $44 million (2003 USD, $61.2 million2021 USD).
|F0||< 73 mph||Light damage|
|F1||73–112 mph||Moderate damage|
|F2||113–157 mph||Considerable damage|
|F3||158–206 mph||Severe damage|
|F4||207–260 mph||Devastating damage|
|F5||261–318 mph||Incredible damage|
Upon making landfall, Bill produced a peak storm surge of 4.99 feet (1.52 m) in Waveland, Mississippi. The storm surge led to beach erosion, damage to piers, and flooded roadways, with damage from the surge amounting to around $1 million (2003 USD, $1.39 million2021 USD). The maximum sustained wind from the storm recorded in Mississippi was 43 miles per hour (69 km/h), at the Gulfport-Biloxi International Airport, while the airport and Keesler Air Force Base both reported a peak wind gust of 52 miles per hour (84 km/h). Tropical Storm Bill dropped moderate to heavy rainfall across the state, peaking at 9.49 inches (241 mm) in Van Cleave. The moderate wind gusts, along with the saturated ground, downed trees in several locations. 34 roads in Pike and Walthall Counties were blocked by fallen trees, and two homes were damaged. Additionally, power outages were reported near the coast. The rainfall flooded streets in various portions of the state and led to overflown rivers. An overflown creek in Pearl River County flooded structures and roadways. The outer rainbands of Bill produced a weak tornado that touched down briefly in Waveland, blowing down several trees which resulted in minor damage to roofs. Statewide damage accrued to $5 million (2003 USD, $6.95 million2021 USD), primarily from flooding.
As Tropical Storm Bill made landfall on Louisiana, its effects were felt in the Alabama coast as well, as heavy surf and tidal flooding pounded the coastline of the state. High waters closed a road to Dauphin Island and portions of a road along Mobile Bay. 3 inches (76 mm) of rain across the southern half of Alabama, with isolated locations receiving over 8 inches (200 mm). Due to wet conditions for months preceding the storm, rainfall from Bill led to flash flooding in many counties. The deluge led to overflown rivers and streams, and left several roadways temporarily impassable from high floodwaters. Saturated grounds and wind gusts of 30 to 35 mph (48–56 km/h) downed numerous trees. Many downed trees landed on power lines, which caused power outages for around 19,000 people. One downed tree destroyed a car, and another damaged a roof of a house. In Lee County, a man was required to be rescued after driving through high flood waters. Roadway flooding resulted in a few minor traffic accidents. Also, the outer bands of the storm spawned an F1 tornado in Crenshaw County. Early in its path, it was narrow, and damage was limited to downed trees, two destroyed sheds, and a few houses experiencing light shingle damage or damage from fallen trees. Later, it expanded to reach a width of 1,800 feet (550 m) as it moved northwestward. The tornado destroyed the roofs of two houses, one of which experienced damage to its walls. The tornado dissipated eight minutes after its 3 miles (4.8 km) path began, resulting in $200,000 in damage (2003 USD, $278 thousand2021 USD) and only slight injuries A second tornado, rated F0 in the Fujita scale, occurred in southwestern Montgomery County. A small tornado with a width of only 180 feet (55 m), it moved to the northwest and tore down a few trees that fell onto a mobile home, a house, and two cars. The tornado dissipated six minutes after its 5 miles (8.0 km) path began. Throughout Alabama, Tropical Storm Bill caused around $300,000 in damage (2003 USD, $417 thousand2021 USD).Bill dropped over
Rainfall from the storm began affecting Florida a few days before the storm formed, and locations in the southern portion of the state received over 3 inches (76 mm) of rain. Along the Florida Panhandle, Bill dropped over 8 inches (200 mm) of rain as it made landfall, closing several roads or leaving them impassable due to flooding. A stationary line of thunderstorms in Okaloosa County produced downpours of up to 6 inches (150 mm) in one hour, resulting in flash flooding which washed out a portion of a bridge. In Bay County, heavy rainfall and flooding damaged 40 homes, while several residents in an apartment in Parker needed to be rescued by boat from the floodwaters. Rough surf produced by the storm killed two swimmers at Panama City Beach, while a dozen had to be rescued. Part of the tornado outbreak spawned by the storm extended into northern Florida. Damage in Florida totaled to around $1 million (2003 USD, $1.39 million2021 USD).
Tropical Storm Bill dropped light rainfall of around 1 inch (25 mm) in northeastern Arkansas and southeastern Missouri, and over 5 inches (130 mm) in isolated parts of eastern Tennessee. The storm also produced moderate rainfall in northwestern Georgia, which peaked at 7.1 inches (180 mm) in Monroe. Areas in southeastern Georgia received generally around 1 inch (25 mm); some coastal areas did not receive any precipitation from the storm. Rainfall resulted in flooding in numerous locations around the Atlanta metropolitan area, leaving some roads impassable or closed. The combination of moist air from the south, cool temperatures from a cold front to the north, and low pressures led to the development of supercells throughout Georgia and South Carolina, several of which produced tornadoes. An F1 tornado touched down 3 miles (4.8 km) north-northeast of Pennington; first it passed through a farm, causing severe damage to two dairy sheds, a John Deere tractor, and three metal storage buildings. The tornado destroyed a hay barn, a carport, and a car inside the carport as well, while also causing a tree to fall and kill one cow. The tornado passed through a forested area, where it toppled or sheared off hundreds of trees. As it entered a more urban area, it downed 30 isolated trees, some of which fell on a portion of Interstate 20, temporarily closing the roadway. The tornado damaged seven houses, primarily to roof damage, although one experienced damage to several windows, while another had a utility trailer and a car damaged by fallen trees; a commercial building was damaged as well. An F2 tornado was reported in Clito, which knocked down trees and damaged mobile homes. Severe thunderstorms from the remnants of Bill caused considerable damage to a house near Louisville and knocked down several trees. Moreover, a tornado was briefly associated with the storms. Bill also caused thunderstorms in Kite which uprooted several trees onto a car and a house. One man in Atlanta died due to a falling tree. Damage in Georgia totaled to $244,500 (2003 USD, $340 thousand2021 USD).
The tornado outbreak spawned by Bill was the greatest in the Charleston, South Carolina National Weather Service area since the outbreak provoked by Hurricane Earl in 1998. One such tornado was an F1 that struck Hampton, 7 inches (180 mm). The rainfall resulted in flash flooding in areas, which caused some damage.which uprooted trees and downed power lines. The tornado severely damaged a Dollar General store, while several houses were damaged from fallen trees. An F1 tornado also touched down near Smoaks, which uprooted several trees, resulted in a crushed car due to a fallen tree, caused severe roof damage to a mobile home, and killed one dog. The storm produced heavy rainfall in the northern portion of the state, with some locations reporting over
In North Carolina, the remnants of the storm dropped around 5 inches (130 mm) in the east-central part of the state, while the southwestern portion of the state received totals of over 7 inches (180 mm). In Raleigh, a boy drowned from the floodwaters. The tornado outbreak from the storm extended into North Carolina, though specifics are unknown. Bill produced light to moderate precipitation in the Mid-Atlantic, including over 5 inches (130 mm) in central Virginia. In Virginia, a line of thunderstorms from the system produced small amounts of hail in Falls Church. The tornado outbreak associated with Bill ended in New Jersey; a narrow F0 tornado briefly touched down in a marsh near Goshen. The tornado remained away from the city, and caused no damage or injuries.
By one day after the storm, power companies restored electricity to 151,000 customers. Citizens in Montegut circulated a petition for a class-action lawsuit in response to the levee failure. families asked for food assistance. The Red Cross also set up a shelter in Houma, where 14 people stayed.The American Red Cross set up a church in Reserve as an emergency shelter. Only five people stayed the first night, resulting in the organization to convert it to a family services center. Over 100
Tropical Storm Allison was a tropical storm that devastated southeast Texas in June of the 2001 Atlantic hurricane season. An arguable example of the "brown ocean effect", Allison lasted unusually long for a June storm, remaining tropical or subtropical for 16 days, most of which when the storm was over land dumping torrential rainfall. The storm developed from a tropical wave in the northern Gulf of Mexico on June 4, 2001, and struck the upper Texas coast shortly thereafter. It drifted northward through the state, turned back to the south, and re-entered the Gulf of Mexico. The storm continued to the east-northeast, made landfall on Louisiana, then moved across the southeast United States and Mid-Atlantic. Allison was the first storm since Tropical Storm Frances in 1998 to strike the northern Texas coastline.
Hurricane Georges was a powerful and long-lived Cape Verde Category 4 hurricane which caused severe destruction as it traversed the Caribbean and Gulf of Mexico in September 1998, making seven landfalls along its path. Georges was the seventh tropical storm, fourth hurricane, and second major hurricane of the 1998 Atlantic hurricane season. It became the most destructive storm of the season, the costliest Atlantic hurricane since Hurricane Andrew in 1992 and remained the costliest until Hurricane Charley in 2004, and the deadliest since Hurricane Gordon in 1994. Georges killed 604 people, mainly on the island of Hispaniola, and caused extensive damage resulting at just under $10 billion in damages mostly in St. Kitts and Nevis, Puerto Rico and Hispaniola.
Hurricane Edith was the strongest hurricane to form during the 1971 Atlantic hurricane season and formerly the southernmost landfalling Category 5 hurricane on record in the Atlantic until 2007. Edith also stands as one of the only Category 5 Atlantic hurricanes to not have its name retired, next to 1953's Hurricane Carol, 1961's Hurricane Esther, 2005's Hurricane Emily, and 2019’s Hurricane Lorenzo. Edith developed from a tropical wave on September 5 and quickly strengthened into a hurricane in the Caribbean Sea. Edith rapidly intensified on September 9 and made landfall on Cape Gracias a Dios as a Category 5 hurricane on the Saffir-Simpson Hurricane Scale. Being a category 5 hurricane, Edith peaked at only 943 mbar (hPa), making Edith the least intense category 5 Atlantic hurricane on record. It quickly lost intensity over Central America and after briefly entering the Gulf of Honduras it crossed the Yucatán Peninsula in Mexico. After moving across the Gulf of Mexico a trough turned the storm to the northeast and Edith, after having restrengthened while accelerating towards the coast, made landfall on Louisiana with winds of 105 mph (170 km/h) on September 16. Edith steadily weakened over land and dissipated over Georgia on September 18.
Hurricane Danny was the only hurricane to make landfall in the United States during the 1997 Atlantic hurricane season, and the second hurricane and fourth tropical storm of the season. The system became the earliest-formed fifth tropical or subtropical storm of the Atlantic season in history when it attained tropical storm strength on July 17, and held that record until the 2005 Atlantic hurricane season when Tropical Storm Emily broke that record by several days. Like the previous four tropical or subtropical cyclones of the season, Danny had a non-tropical origin, after a trough spawned convection that entered the warm waters of the Gulf of Mexico. Danny was guided northeast through the Gulf of Mexico by two high pressure areas, a rare occurrence in the middle of July. After making landfall on the Gulf Coast, Danny tracked across the southeastern United States and ultimately affected parts of New England with rain and wind.
Hurricane Claudette was a moderately strong tropical cyclone that struck South Texas in July 2003. A fairly long-lived July Atlantic hurricane, Claudette was the fourth depression, third tropical storm and first hurricane of the 2003 Atlantic hurricane season. Claudette began as a tropical wave in the eastern Caribbean. It moved quickly westward, brushing past the Yucatán Peninsula before moving northwestward through the Gulf of Mexico. Claudette remained a tropical storm until just before making landfall in Port O'Connor, Texas, when it quickly strengthened to a strong Category 1 hurricane on the Saffir-Simpson Hurricane Scale. Forecasting of its path and intensity was uncertain throughout its lifetime, resulting in widespread and often unnecessary preparations along its path.
Tropical Storm Arlene was an unusually large and early-forming tropical storm, being the first of twenty-eight different storms during the 2005 Atlantic hurricane season, which would become the second most active season on record. Tropical Storm Arlene formed near Honduras on June 8 and moved northwards. It crossed western Cuba on June 10 and strengthened to just under hurricane strength before making its final landfall on the Florida Panhandle the next day. The storm weakened as it continued to move north over the United States, becoming extratropical on June 13. Arlene was responsible for only one death and minor damage.
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 (381 mm) in northern Louisiana. Damage was minimal, totaling $305,000 (2004 USD), and no casualties were reported.
Tropical Storm Fay was the sixth named storm of the 2002 Atlantic hurricane season; it was a moderate tropical storm which caused flooding in parts of Texas and Northern Mexico. It formed from a trough of low pressure that moved south into the Gulf of Mexico, and became stationary. A low pressure center developed along this trough, and on September 5, a Hurricane Hunter aircraft reported that the system had gained sufficient organization to be classified a tropical depression, 95 miles (153 km) southeast of Galveston. The depression drifted south-southwest while strengthening, reaching its peak strength of 60 miles per hour (97 km/h) on the morning of September 6. The system then made an abrupt turn to the west-northwest, and remained steady in strength and course until landfall the next day, near Matagorda. The system weakened rapidly after landfall degenerating into a remnant low on September 8, but the storm's circulation survived for another three days.
Tropical Storm Doria was the costliest tropical cyclone in the 1971 Atlantic hurricane season. The fifth tropical storm of the season, Doria developed from a tropical wave on August 20 to the east of the Lesser Antilles, and after five days without development it attained tropical storm status to the east of Florida. Doria turned to the north, and reached peak winds of 65 mph (105 km/h) as it was making landfall near Morehead City, North Carolina. It turned to the northeast, and moved through the Mid-Atlantic and New England as a tropical storm before becoming an extratropical storm over Maine on August 29.
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.
Hurricane Fern was the sixth named storm and fourth hurricane of the 1971 Atlantic hurricane season. It formed from a tropical wave which interacted with a large trough of low pressure to form Fern, as well as Hurricane Ginger, Tropical Storm Heidi, and a system later designated as Tropical Depression Sixteen, which moved into South Carolina. Fern crossed southeastern Louisiana as a tropical depression on September 4 before swinging back out over the Gulf of Mexico. Fern reached hurricane status on September 8, reaching a peak intensity of 90 mph (140 km/h) before making landfall near Freeport, Texas, two days later.
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-northeastward 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.
