Hurricane Isbell was first identified as a weak tropical disturbance on October 7, 1964 over the western Caribbean. Situated to the south of a diffuse trough, the system remained weak and relatively disorganized as it moved generally northwest near Honduras and Nicaragua. Despite the presence of an upper-level anticyclone, which promotes favorable outflow for tropical cyclones and aids in tropical cyclogenesis, a lack of distinct low-level inflow inhibited intensification. Additionally, an area of warm mid-tropospheric air was present within the cyclone. Though a disheveled system, [1] it is analyzed to have become a tropical depression by 12:00  UTC on October 8. The following day, the depression skirted the eastern coast of Honduras. [2] Operationally, it was not until October 10 that the Weather Bureau initiated advisories on the depression. [1] On that date, a weather reconnaissance mission into the system found a weak low-level circulation with a barometric pressure of 1007.3  mb (hPa; 29.75  inHg) and winds of 20–30 mph (32–48 km/h) in squalls. [3] Throughout October 11 and 12, the depression slowly executed a tight cyclonic loop over the northwestern Caribbean Sea. It finally organized into a tropical storm and was given the name Isbell by 00:00 UTC on October 13 after completing the loop and acquiring a north-northeast trajectory. [2]

Throughout October 13, marked intensification of the cyclone occurred. [1] Over a 24‑hour span, ending at 18:00 UTC, its central pressure fell from 1005 mb (hPa; 29.68 inHg) to 979 mb (hPa; 28.91 inHg) which was reflected in Isbell's winds more than doubling from 35 to 90 mph (56 to 145 km/h). [2] Shortly thereafter, the storm made landfall in extreme western Cuba, near Guane, before emerging over the southeastern Gulf of Mexico. [1] Isbell's brief stint over land did not hinder development, which continued unabated until 12:00 UTC on October 14 at which time it reached its maximum intensity. Situated to the south of Key West, Florida, Isbell attained winds of 125 mph (201 km/h) which ranks it as a Category 3 hurricane on the modern-day Saffir–Simpson hurricane wind scale. Additionally, its central pressure bottomed out at 964 mb (hPa; 28.47 inHg). [2] Around this time, a new low-pressure area formed 300 mi (480 km) to Isbell's northwest over the Gulf in response to a powerful cold-core low over the Mississippi Valley. The cyclonic flow of this second system brought cool, dry air from the north and circulated it into the hurricane. This in turn caused the storm to become asymmetric in structure with radar imagery indicating little to no reflectivity along the western periphery of the hurricane. [1]

The degrading structure of Isbell resulted in some weakening as it accelerated toward Florida. At 22:00 UTC on October 14, the hurricane made landfall near Everglades City as a Category 2 with sustained winds between 100 and 110 mph (160 and 180 km/h). [1] [4] Within five hours, the system cleared the Florida Peninsula and emerged over the western Atlantic Ocean north of West Palm Beach. [5] The storm's passage over land resulted in notable weakening, though Isbell remained of hurricane-strength. During the afternoon of October 15, the low that had formed the previous day induced a northward turn of the cyclone and directed it toward North Carolina, a result of what is known as the Fujiwhara effect. [1] Thereafter, the two systems began to intertwine as Isbell began transitioning into an extratropical cyclone; rapid weakening accompanied this phase. [6] Isbell completed this process by 12:00 UTC on October 16 as it moved onshore near Morehead City, North Carolina. [2] [6] On October 17 the two non-tropical systems merged into a single storm over the Outer Banks. [6] Isbell's remnants emerged back over the Atlantic Ocean on October 18 near the Delmarva Peninsula before accelerating northeast. The system was last noted on October 19 as it moved over Atlantic Canada. [7]

In Cuba, thousands were evacuated due to flooding lowlands. [8] Advisories were broadcast and issued warning of the possibility of heavy rains and winds, isolated small hail, and possible isolated tornadoes in Florida from 21:00 UTC on October 14 to 02:00 UTC on October 15. The aviation severe weather forecast also warned residents in south and central Florida of up to 0.75 in (19 mm) of hail, gusts of up to 53 mph (85 km/h), and the potential for tornadic activity. Flood warnings were also issued, with predictions of flooding 4 ft (1.2 m) above flood stage. [9] Emergency preparations at Key West's weather office were made. In the morning hours of October 13, the office alerted city, county, and military officials. In the afternoon, they completed office preparations and scheduling. On October 14, the office requested radio stations to stay on the air and relayed hourly reports. [10]

In North Carolina, some tidal flooding was also forecast. People were warned to tune to television and radio broadcasts. [11] On October 15, as Isbell rapidly crossed Florida, forecasters at the Charleston, South Carolina Weather Bureau warned of high tides of up to 12 ft (3.7 m), 5 ft (1.5 m) above flood-stage, from South Carolina into North Carolina. Owing to the continued northeastward movement of the storm, tides ultimately did not exceed 2 ft (0.61 m) in South Carolina. [12] Across coastal areas of North Carolina, alerts for severe thunderstorms, tornadoes, and high tides were raised; however, the storm greatly diminished before reaching shore and little damage materialized. [13] Moderate rains along the lower Neuse River basin were expected to prolong flooding triggered by Hurricane Hilda and its remnants earlier in October. [14] Small craft advisories were raised northward to Provincetown, Massachusetts, through October 18. [15]

Cuba

Skirting the extreme western coast of Cuba on October 13, the storm produced gusts estimated at 100 mph (160 km/h) in Pinar del Río Province. [16] The highest measured sustained winds were 85 mph (137 km/h) in Guane and 70 mph (110 km/h) at Rancho-Boyeros Airport in the capital city of Havana. Additionally, pressures at the city fell to 979 mbar (hPa; 28.91 inHg). [1] Heavy rains caused rivers to over-top their banks, forcing thousands of people to evacuate. [17] Three fatalities occurred in Guane due to collapsing homes. [1] [18] A fourth fatality took place elsewhere in Cuba. [19] Numerous homes were damaged or destroyed by the storm, with exact numbers unknown. The region's tobacco crop also sustained considerable losses with fields and warehouses destroyed. [16] The damage to agriculture compounded economic losses in Cuba that resulted from Hurricane Flora in September 1963, which devastated the nation, as well as impacts from Hurricanes Cleo and Hilda earlier in 1964. [20] The combined effects of Cleo, Hilda, and Isbell resulted in economic losses of approximately $100 million in the country, of which at least $20 million was directly attributed to Isbell. [21]

Florida

Though Isbell struck the state as a Category 2 hurricane, [4] no winds in excess of 100 mph (160 km/h) were reported. Measurements peaked at 90 mph (140 km/h) at both Everglades City and Indiantown. Hurricane-force gusts were measured in Belle Glade, Fort Lauderdale, Key West, Pompano Beach, and West Palm Beach. Atmospheric pressures fell to 970.7 mb (hPa; 28.67 inHg) in the Dry Tortugas and 977.5 mb (hPa; 28.87 inHg) on the mainland in Juno Beach. [1] Rainfall in the state was relatively limited owing to the brisk movement of the storm, though a frontal system immediately preceding the hurricane brought heavy rains to the state. A peak total of 9.46 in (240 mm) was measured in West Palm Beach, though an estimated 80% of this was attributable to the front. [7] Amounts from the hurricane itself were likely around 5 in (130 mm). No major storm surge was reported during Isbell's passage due to greatly weaker winds in the back half of the storm. Tides in Key West rose 4 to 5 ft (1.2 to 1.5 m) above normal. [1]

Throughout Florida, three people were killed in relation to the storm and no more than $10 million in damage occurred, with more than half of which was attributed to agricultural losses. [1] In addition, 76 people were injured, 12 of whom required hospitalization. Structural damage was relatively limited, with only 63 homes and businesses, mostly trailers, being destroyed; 159 other structures sustained major damage while a further 631 experienced minor damage. [22] The majority of damage from Isbell was not from the hurricane itself but rather tornadoes spawned by its outer bands. [1] At least nine, and as many as twelve, tornadoes affected the state with the greatest effects being felt in the Miami metropolitan area. All storm-related injuries were attributed to these tornadoes as well as the majority of structural damage. [23] According to the National Climatic Data Center, four of these tornadoes were of F2 intensity. [24]

Despite the close passage of the storm to the Florida Keys, damage in the area was light and amounted to $175,000. [1] Of this, $125,000 was attributed to structural damage. Hurricane-force winds in the archipelago only lasted 15 minutes and gale-force winds occurred over a 5-hour span. The brevity of damaging winds limited the effects of the storm. Most damage was constrained to downed trees, signs, and power poles. Two trailers were overturned, however, and an oil barge sank in the Key West Harbor. [25] Two people drowned after their shrimp boat was destroyed. [1] In and around the Fakahatchee Strand Preserve State Park, Royal Palms, and Royal Poincianas were defoliated by the hurricane's winds. Downed trees and power lines in Collier County temporarily left many customers without phone and electrical service. Residents in nearby Lee Cypress stated that the effects from Isbell were worse than Hurricane Donna which struck the region as a Category 4 in September 1960. [26]

Palm Beach County was the most affected area, accounting for more than half of the losses, [22] [27] and approximately $700,000 in damage. [28] One indirect death occurred when a man suffered a heart attack in Lake Worth while installing storm shutters. [1] [28] At least three tornadoes were spawned in Palm Beach County. The strongest was an F2 that struck a trailer park in Briny Breezes, damaging numerous trailers and injuring 22 people. Shortly thereafter the same tornado or possibly a second one struck Boynton Beach, injuring three people and damaging several structures. [23] [24] The event lasted roughly 20 minutes and the tornadoes moved along a path 10 mi (16 km) long. [29] [30] Another tornado in Boca Raton caused a number of minor injuries. In West Palm Beach, a twister that crossed the intersection of State Roads 802 and 809 damaged adjacent properties and injured several people. [23] Throughout Palm Beach County, 492 homes suffered damage, while 36 mobile homes were demolished and 60 others were inflicted major impact. Additionally, 33 farm buildings and 9 small businesses were severely damaged or destroyed. [22]

In Martin County, an F2 was spawned in Hobe Sound and affected the area near U.S. Route 1. [23] About 39 homes and 13 mobile homes were damaged, while two farm buildings and two businesses also received impact. [22] The fourth F2 tornado was spawned in Brevard County near Eau Gallie. It caused extensive damage and injured 17 people in the Orange Court trailer park. [23] [24] Collectively, 35 homes in Flagler and Volusia counties were damaged. [22]

The Carolinas and elsewhere

Heavy rains associated with Isbell and a nearby non-tropical low resulted in heavy rains across The Carolinas on October 15 and 16. In and around the Columbia, South Carolina area, 3 to 6 in (76 to 152 mm) of rain fell, with a peak of 6.11 in (155 mm) in the city itself. Significant flooding took place along all rivers in the state; [31] the Broad River crested at 32.1 ft (9.8 m), its highest level since 1940, in Blair. The Pee Dee River rose to 39 ft (12 m) at Cheraw by October 18, roughly 9 ft (2.7 m) above flood-stage. [32] The cotton crop sustained the greatest losses during the event, with damage estimated in excess of $1 million. [31] Along the coast, tides rose to 6.2 ft (1.9 m), 2.1 ft (0.64 m) above normal, in Charleston Harbor. What little coastal flooding took place mostly resulted from wave run-up rather than tidal flooding. Some beach erosion occurred in exposed areas. [33]

Much of North Carolina was affected by Isbell with rain extending into interior parts of the state. Totals were generally light, however, and peaked at around 5 in (130 mm) in eastern areas. Some flash flooding took place in the Piedmont, though overall effects were minimal. [34] In the Blue Ridge Mountains, the French Broad River topped its banks and prompted evacuations in Hot Springs and Marshall. [15] The greatest impacts were felt along the Neuse River in Kinston within Lenoir County. Rains from Isbell exacerbated ongoing floods in the area, resulting in heavy damage to many homes. [32] A man was swept away by swift currents near a Duke Energy steam plant in Cliffside; however, it is unknown if he perished or was later rescued. [35] Losses to the peanut crop were extensive, though no monetary value is available. [1] With the storm arriving at low-tide, no notable coastal flooding occurred. [34] The significant weakening of Isbell prior to landfall also lessened the effects from wind as gale-force winds were mostly constrained to coastal areas; a peak gust of 75 mph (121 km/h) was measured in Elizabeth City. [1]

Elsewhere along the East Coast, the remnants of Isbell produced generally light to moderate rain. A localized maximum of around 5 in (130 mm) occurred in Massachusetts as the system began to dissipate. [7] Immediately following the storm, an unseasonably strong cold front brought near-freezing temperatures to Virginia, resulting in frost. The combination of the cold air and the hurricane prevented any peanut bumper crop harvesting in the state. [36]

<span class="mw-page-title-main">2004 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 2004 Atlantic hurricane season was a very deadly, destructive, and extremely active Atlantic hurricane season, with over 3,200 deaths and more than $61 billion in damage. More than half of the 16 tropical cyclones brushed or struck the United States. Due to the development of a Modoki El Niño – a rare type of El Niño in which unfavorable conditions are produced over the eastern Pacific instead of the Atlantic basin due to warmer sea surface temperatures farther west along the equatorial Pacific – activity was above average. The season officially began on June 1 and ended on November 30, though the season's last storm, Otto, dissipated on December 3, extending the season beyond its traditional boundaries. The first storm, Alex, developed offshore of the Southeastern United States on July 31, one of the latest dates on record to see the formation of the first system in an Atlantic hurricane season. It brushed the Carolinas and the Mid-Atlantic, causing one death and $7.5 million (2004 USD) in damage. Several storms caused only minor damage, including tropical storms Bonnie, Earl, Hermine, and Matthew. In addition, hurricanes Danielle, Karl, and Lisa, Tropical Depression Ten, Subtropical Storm Nicole and Tropical Storm Otto had no effect on land while tropical cyclones. The season was the first to exceed 200 units in accumulated cyclone energy (ACE) since 1995, mostly from Hurricane Ivan, the storm produced the highest ACE. Ivan generated the second-highest ACE in the Atlantic, only behind 1899 San Ciriaco Hurricane.

<span class="mw-page-title-main">1958 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1958 Atlantic hurricane season included every tropical cyclone either affecting or threatening land. There were ten named storms as well as one pre-season tropical storm. Seven of the storms became hurricanes, including five that were major hurricanes, or the equivalent of a Category 3 on the Saffir-Simpson scale. The strongest storm was Hurricane Helene, which became a strong Category 4 hurricane with 150 mph (240 km/h) winds and a barometric pressure of 930 millibars (27 inHg) while just offshore the southeastern United States.

<span class="mw-page-title-main">1960 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1960 Atlantic hurricane season was the least active season since 1952. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, an unnamed storm, developed in the Bay of Campeche on June 22. It brought severe local flooding to southeastern Texas and was considered the worst disaster in some towns since a Hurricane in 1945. The unnamed storm moved across the United States for almost a week before dissipating on June 29. In July, Hurricane Abby resulted in minor damage in the Leeward Islands, before impacting a few Central American counties — the remnants of the storm would go on to form Hurricane Celeste in the East Pacific. Later that month, Tropical Storm Brenda caused flooding across much of the East Coast of the United States. The next storm, Hurricane Cleo, caused no known impact, despite its close proximity to land.

<span class="mw-page-title-main">1961 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1961 Atlantic hurricane season was a hyperactive Atlantic hurricane season, with an accumulated cyclone energy (ACE) total of 189. The season, however, was an average one in terms of named storms. The season featured eight hurricanes and a well above average number of five major hurricanes. It was previously thought that the season had a record-tying seven major hurricanes, before the Atlantic hurricane reanalysis project downgraded two storms in 2019. Two Category 5 hurricanes were seen in 1961, making it one of only seven Atlantic hurricane seasons to feature multiple Category 5 hurricanes in one season. The season started on June 15, and ended on November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, an operationally unclassified tropical depression, formed offshore east Central Florida on June 10, but dissipated a few days later. Next, Hurricane Anna developed in the eastern Caribbean Sea near the Windward Islands on July 20. It brought minor damage to the islands, as well as wind and flood impacts to Central America after striking Belize as a hurricane. Anna caused one death and about $300,000 (1961 USD) in damage. Activity went dormant for nearly a month and a half, until Hurricane Betsy developed on September 2. Betsy peaked as a Category 4 hurricane, but remained at sea and caused no impact.

<span class="mw-page-title-main">1963 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1963 Atlantic hurricane season featured one of the deadliest tropical cyclones on record in the Atlantic basin: Hurricane Flora. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was a slightly below average season in terms of tropical storms, with a total of ten nameable storms. The first system, an unnamed tropical storm, developed over the Bahamas on June 1. In late July, Hurricane Arlene, developed between Cape Verde and the Lesser Antilles. The storm later impacted Bermuda, where strong winds resulted in about $300,000 (1963 USD) in damage. Other storms such as hurricanes Beulah and Debra, as well as an unnamed tropical storm, did not impact land. During the month of September, Tropical Storm Cindy caused wind damage and flooding in Texas, leaving three deaths and approximately $12.5 million in damage. Hurricane Edith passed through the Lesser Antilles and the eastern Greater Antilles, causing 10 deaths and about $43 million in damage, most of which occurred on Martinique.

<span class="mw-page-title-main">1964 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1964 Atlantic hurricane season featured the highest number of U.S.-landfalling hurricanes since 1933. The season officially began on June 15, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season was above average, with thirteen named storms, seven hurricanes, and five major hurricanes. The first system, an unnamed tropical storm, developed on June 2, almost two weeks before the official start of the season. Striking Florida on June 6, the storm brought localized flooding to portions of Cuba and the Southeastern United States, leaving about $1 million in damage. The next storm, also unnamed, developed near the end of July; it did not impact land.

<span class="mw-page-title-main">Hurricane Betsy</span> Category 4 Atlantic hurricane in 1965

Hurricane Betsy was an intense, deadly and destructive tropical cyclone that brought widespread damage to areas of Florida and the central United States Gulf Coast in September 1965. The storm's erratic nature, coupled with its intensity and minimized preparation time contributed to making Betsy the first tropical cyclone in the Atlantic basin to accrue at least $1 billion in damage. While the storm primarily affected areas of southern Florida and Louisiana, lesser effects were felt in the Bahamas and as far inland in the United States as the Ohio River Valley. Betsy began as a tropical depression north of French Guiana on August 27, and strengthened as it moved in a general northwesterly direction. After executing a slight anticyclonic loop north of the Bahamas, Betsy proceeded to move through areas of south Florida on September 8, causing extensive crop damage. After emerging into the Gulf of Mexico, the cyclone strengthened and reached its peak intensity equivalent to that of a Category 4 hurricane on September 10 before making its final landfall near Grand Isle, Louisiana, shortly thereafter. Once inland, Betsy was slow to weaken, and persisted for two more days before degenerating into an extratropical storm; these remnants lasted until September 13.

<span class="mw-page-title-main">1966 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1966 Atlantic hurricane season saw the Weather Bureau office in Miami, Florida, be designated as the National Hurricane Center (NHC) and assume responsibility of tropical cyclone forecasting in the basin. The season officially began on June 1, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was an above-average season in terms of tropical storms, with a total of 15. The first system, Hurricane Alma, developed over eastern Nicaragua on June 4 and became the most recent major hurricane in the month of June. Alma brought severe flooding to Honduras and later to Cuba, but caused relatively minor impact in the Southeastern United States. Alma resulted in 91 deaths and about $210.1 million (1966 USD) in damage.

<span class="mw-page-title-main">1968 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1968 Atlantic hurricane season was a below average hurricane season during which only seven named storms developed. The season officially began on June 1 and lasted until November 30, dates which conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. Of the named storms, five strengthened into hurricanes; none however intensified into a major hurricane. Only four other seasons since the start of the satellite era—1972, 1986, 1994, and 2013—did not feature a major hurricane. The first system, Hurricane Abby, developed in the northwestern Caribbean on June 1. Abby moved northward and struck Cuba, bringing heavy rainfall and flooding to western portions of the island. Making landfall in Florida on June 4, Abby caused flooding and spawned four tornadoes, but left behind little damage. Overall, the hurricane resulted in six deaths and about $450,000 (1968 USD) in damage. In late June, Tropical Storm Candy brought minor flooding and spawned several tornadoes across portions of the Southern United States. Overall damage from the cyclone reached approximately $2.7 million. 1968 featured two simultaneously active tropical storms during the month of June, a phenomenon that would not occur again until 2023.

<span class="mw-page-title-main">1969 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1969 Atlantic hurricane season was the most active Atlantic hurricane season since the 1933 season, and was the final year of the most recent positive ("high-quality") Atlantic multidecadal oscillation (AMO) era. The hurricane season officially began on June 1, and lasted until November 30. The season had the highest number of systems reach hurricane status – twelve – in a single season, until that record was surpassed in 2005. The season was above-average despite an El Niño, which typically suppresses activity in the Atlantic Ocean, while increasing tropical cyclone activity in the Pacific Ocean. Activity began with a tropical depression that caused extensive flooding in Cuba and Jamaica in early June. On July 25, Tropical Storm Anna developed, the first named storm of the season. Later in the season, Tropical Depression Twenty-Nine caused severe local flooding in the Florida Panhandle and southwestern Georgia in September.

<span class="mw-page-title-main">1985 Atlantic hurricane season</span> Hurricane season in the North Atlantic Ocean

The 1985 Atlantic hurricane season had six United States landfalling hurricanes, tied with 1886 and 2020 for the highest number on record. The season officially began on June 1 and lasted until November 30. It was an average season, with 11 named storms developing. This was partially attributed to a La Niña – a meteorological phenomenon that produces favorable conditions across the Atlantic basin, such as lower wind shear and higher sea surface temperatures. The first storm, Ana, developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone. Three other tropical cyclones – Claudette, Henri, and Isabel – did not significantly affect land. Claudette developed offshore of the Southeastern United States and brushed Bermuda and the Azores. Henri and Isabel were dissipating as they approached land. However, the precursor of the latter caused a severe flood in Puerto Rico that killed 180 people. Additionally, Tropical Storm Fabian and three tropical depressions did not have any known impact on land.

<span class="mw-page-title-main">1989 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1989 Atlantic hurricane season was an average hurricane season with 11 named storms. The season officially began on June 1, and ended on November 30. The first tropical cyclone, Tropical Depression One, developed on June 15, and dissipated two days later without any effects on land. Later that month, Tropical Storm Allison caused severe flooding, especially in Texas and Louisiana. Tropical Storm Barry, Tropical Depressions Six, Nine, and Thirteen, and Hurricanes Erin and Felix caused negligible impact. Hurricane Gabrielle and Tropical Storm Iris caused light effects on land, with the former resulting in nine fatalities from rip currents offshore the East Coast of the United States and Atlantic Canada, while the latter produced minor flooding in the United States Virgin Islands.

<span class="mw-page-title-main">Hurricane Hilda</span> Category 4 Atlantic hurricane in 1964

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">1904 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1904 Atlantic hurricane season featured no tropical cyclones during the months of July and August. The season's first cyclone was initially observed in the southwestern Caribbean on June 10. After this storm dissipated on June 14, the next was not detected until September 8. The sixth and final system transitioned into an extratropical cyclone offshore South Carolina on November 4. Two of the six tropical cyclones existed simultaneously.

<span class="mw-page-title-main">1897 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1897 Atlantic hurricane season was an inactive season, featuring only six known tropical cyclones, four of which made landfall. There were three hurricanes, none of which strengthened into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. The first system was initially observed south of Cape Verde on August 31, an unusually late date. The storm was the strongest of the season, peaking as a Category 2 hurricane with winds of 100 mph (155 km/h). While located well north of the Azores, rough seas by the storm sunk a ship, killing all 45 crewmen. A second storm was first spotted in the Straits of Florida on September 10. It strengthened into a hurricane and tracked northwestward across the Gulf of Mexico, striking Louisiana shortly before dissipating on September 13. This storm caused 29 deaths and $150,000 (1897 USD) in damage.

<span class="mw-page-title-main">Tropical Storm Arlene (1993)</span> Atlantic tropical storm in 1993

Tropical Storm Arlene brought torrential rainfall to the western United States Gulf Coast, particularly to the U.S. state of Texas, in June 1993. The first named storm of the 1993 Atlantic hurricane season, Arlene developed from an area of low pressure in the Bay of Campeche on June 18. The depression slowly strengthened as it tracked west-northwestward and later north-northwestward across the western Gulf of Mexico. Arlene was subsequently upgraded to a tropical storm on June 19, but failed to intensify further due to its proximity to land. The cyclone then made landfall on Padre Island, Texas, with winds of 40 mph (65 km/h) and degenerated into a remnant disturbance on June 21.

<span class="mw-page-title-main">Hurricane Abby (1968)</span> Category 1 Atlantic hurricane in 1968

Hurricane Abby made landfall in Cuba, Florida, and North Carolina in June 1968. The first tropical cyclone, first named storm, and first hurricane on the season, Abby developed over the northwestern Caribbean Sea on June 1, as a result of the interaction between a mid-tropospheric trough and a cold front. Moving generally north-northeastward, the depression slowly strengthened while approaching the western tip of Cuba, becoming Tropical Storm Abby late on June 2. Shortly thereafter, Abby made landfall in Pinar del Río Province. The storm dropped heavy rainfall in western Cuba, with up to 12 inches (300 mm) on Isla de la Juventud. However, no flooding was reported. After reaching the southeastern Gulf of Mexico on June 3, Abby strengthened further and became a Category 1 hurricane on the modern-day Saffir–Simpson hurricane wind scale. However, early on June 4, Abby weakened to a tropical storm. Around midday on June 4, the system made landfall near Punta Gorda, Florida as a strong tropical storm.

<span class="mw-page-title-main">Tropical Storm Abby (1964)</span> Atlantic tropical storm in 1964

Tropical Storm Abby was an exceptionally small tropical cyclone that had minor effects across Southeast Texas in early August 1964. Forming as a tropical depression out of a trough south of Louisiana on August 5, the system moved generally westward. It was not until August 7 that the system began to organize. That day, an eye rapidly formed within the system and it became a tropical storm just 60 mi (95 km) southeast of Galveston, Texas. Soon thereafter, a weather reconnaissance plane reported a barometric pressure of 1000 mbar at the storm's center. Around 18:00 UTC, the newly named Abby attained peak winds of 70 mph (115 km/h). It subsequently made landfall near Matagorda, Texas four hours later. Once onshore gradual weakening ensued, though a brief period of re-organization delayed its dissipation. Abby degenerated into an area of showers on August 8 southwest of San Antonio, Texas.

<span class="mw-page-title-main">Tropical Storm Andrea (2013)</span> Atlantic Tropical storm in the 2013

Tropical Storm Andrea brought flooding to Cuba, the Yucatan Peninsula, and portions of the East Coast of the United States in June 2013. The first tropical cyclone and named storm of the annual hurricane season, Andrea originated from an area of low pressure in the eastern Gulf of Mexico on June 5. Despite strong wind shear and an abundance of dry air, the storm strengthened while initially heading north-northeastward. Later on June 5, it re-curved northeastward and approached the Big Bend region of Florida. Andrea intensified and peaked as a strong tropical storm with winds at 65 mph (105 km/h) on June 6. A few hours later, the storm weakened slightly and made landfall near Steinhatchee, Florida later that day. It began losing tropical characteristics while tracking across Florida and Georgia. Andrea transitioned into an extratropical cyclone over South Carolina on June 7, though the remnants continued to move along the East Coast of the United States, until being absorbed by another extratropical system offshore Maine on June 10.

<span class="mw-page-title-main">Tropical Storm Colin (2016)</span> Atlantic tropical storm in 2016

Tropical Storm Colin was the earliest third named storm in the Atlantic basin on record for four years, until it was surpassed by Tropical Storm Cristobal in 2020. An atypical, poorly organized tropical cyclone, Colin developed from a low pressure area over the Gulf of Mexico near the northern coast of the Yucatán Peninsula late on June 5, 2016. Moving northward, the depression strengthened into a tropical storm about eight hours after its formation. On June 6, Colin curved to the north-northeast and intensified slightly to winds of 50 mph (80 km/h). Strong wind shear prevented further strengthening and resulted in the system maintaining a disheveled appearance on satellite imagery. Later, the storm began accelerating to the northeast. Early on June 7, Colin made landfall in rural Taylor County, Florida, still at peak intensity. The system rapidly crossed northern Florida and emerged into the Atlantic Ocean several hours later. By late on June 7, Colin transitioned into an extratropical cyclone offshore North Carolina before being absorbed by a frontal boundary the following day.
