The 1940 South Carolina hurricane was a Category 2 hurricane that struck the Georgia and South Carolina coast between August 11 and 12,1940. After forming north of the Leeward Islands,the storm moved west-northwest,moving east of the Bahamas before resuming a west-northwest track towards the Southeastern United States. Hurricane warnings were in effect for the United States coastline near and north of where the center made landfall. A 13-foot storm tide was measured along the South Carolina coast,while over 15 inches (380 mm) of rain fell across northern North Carolina. Significant flooding and landslides struck Georgia,North Carolina,Tennessee,and Virginia during the system's slow trek as a weakening tropical storm,and then as an extratropical cyclone,through the Southeast. The landslides which struck North Carolina were considered a once in a century event. Damages relating to the storm totaled $13 million (1940 USD) and 50 people perished.
Morning weather charts detected a "slight" disturbance between St. Martin and St. Thomas on August 5. [1] Around 18:00 UTC that day, a tropical depression developed about 30 mi (48 km) west-northwest of Anegada in the British Virgin Islands. [2]
The storm moved moving west-northwest near the Mona Passage, bringing squalls of 44 miles per hour (71 km/h) to San Juan, Puerto Rico. On August 6, the developing storm was near the southeastern Bahamas, bringing moderate to rough seas. The cyclone turned northward after its close approach to the southeastern Bahamas. By August 10 a ship reported that winds were hurricane force. In the afternoon of August 11, the hurricane made landfall near Beaufort, South Carolina where it moved inland and turned just northeast of Savannah, Georgia between 5 and 6 p.m. on the same day. Savannah's wind peaked at 73 miles per hour (117 km/h) and the pressure fell to 28.78 inches of mercury (975 hPa). It was the area's worst storm in 29 years. [3] Hurricane-force winds were witnessed between Savannah and Charleston. Weakening into a tropical storm that evening, for the next four or five days the storm meandered inland as a weak tropical storm before evolving into an extratropical cyclone on the evening of August 14. [2]
From August 7 and 9, small craft were advised to exercise caution over the eastern Bahamas and western subtropical Atlantic Ocean as the system approached the region. [4] [5] [6] By 9:30 a.m. on August 10, small craft warnings were in effect for the extreme northern Bahamas, and along the United States coast from Miami, Florida to Cape Hatteras, North Carolina. [7] By the morning of August 11, storm warnings were in effect from Wilmington, North Carolina northward to Cape Hatteras and from Savannah, Georgia to Fernandina Beach, Florida. Hurricane warnings were in effect from Savannah northward to Wilmington. [8] All coastal warnings were dropped by August 12. [9]
A storm tide of 13 feet (4.0 m) was measured along the coast of South Carolina. [10] The cyclone inflicted $1.5 million in damage in Charleston, South Carolina, while Savannah, Georgia received $1 million in damage. Damage to the country's coastline totaled $3 million (1940 USD). Two people at Savannah died, one of whom from heart failure due to fright. [1] Near the point of landfall, a total of 10.84 inches (275 mm) of rainfall fell at Beaufort, South Carolina within a 24-hour period. [11] The highest reported rainfall amount in Georgia was recorded was 13.68 inches (347 mm) one mile east of Louisville while the highest amount in South Carolina was reported from Charleston, where 12.66 inches (322 mm) fell. [12] On the coastal areas where the hurricane hit, there was a considerable loss of life. Early press reports said that 35 had died. According to the Monthly Weather Review, the deaths were low because of hurricane warnings and evacuations. However, modern sources indicate that 50 people died during this storm. [13]
After leaving the coast, the dissipating storm brought heavy rains that sparked disastrous flash floods. The floods inundated much of Tennessee, the Carolinas and northern Georgia. Rainfall amounts across western North Carolina exceeded 15 inches (380 mm), with the highest amount recorded at Idlewild, where 20.65 inches (525 mm) fell. [12] Landslides were common in the mountains of western North Carolina, where it is considered a once in over 100 year landslide event. [14] The East Tennessee and Western North Carolina railroad line was severed so badly it ceased operation. [15] The peak discharge of the flood along Wilson Creek near Adako, North Carolina was estimated at 99,000 cubic feet per second (2,800 m3/s). [16] A total of 26 perished during the Deep Gap Debris Flow in Watauga County, North Carolina alone. [17] Major portions of the county were cut off for two weeks. Debris flows and flooding cut off U.S. Highway 421 in 21 places through a six-mile stretch of roadway between Deep Gap and Maple Springs in Wilkes County, North Carolina. Flooding destroyed 90% of the bridges in Caldwell County, North Carolina. [18] Press reports stated that 30 people died in the floods. Damage amounted to over $10 million (1940 USD). [19]
Rains began in Virginia on August 13, as the system entered the state from the west. Deluges flooded locations across southern and western sections of the Old Dominion. Hampton Roads measured 4.76 inches (121 mm) of rainfall. The highest rainfall amount statewide was recorded at Copper Hill, where 17.03 inches (433 mm) fell. [20] Emporia, on the Meherrin River, recorded a flood of record on August 17 when the river crested at 31.50 feet (9.60 m), which was 8.5 feet (2.6 m) feet above flood stage. Mountain rivers and streams overflowed, washing out bridges and causing landslides which blocked roads. Several highways between Norfolk, southwest Virginia, and Asheville, North Carolina were closed. A collision on August 13 involving the oil screw F.B. Scarbrough 5 miles (8.0 km) above Coles Point may have been caused by this system. [21]
Hurricane Fran caused extensive damage in the United States in early September 1996. The sixth named storm, fifth hurricane, and third major hurricane of the 1996 Atlantic hurricane season, Fran developed from a tropical wave near Cape Verde on August 23. Due to nearby Hurricane Edouard, the depression remained disorganized as it tracked westward, though it eventually intensified into Tropical Storm Fran on August 27. While heading west-northwestward, Fran steadily strengthened into a hurricane on August 29, but weakened back to a tropical storm on the following day. On August 31, Fran quickly re-intensified into a hurricane. By September 2, Fran began to parallel the islands of the Bahamas and slowly curved north-northwestward. Early on September 5, Fran peaked as a 120 mph (195 km/h) Category 3 hurricane. Thereafter, Fran weakened slightly, before it made landfall near Cape Fear, North Carolina early on September 6. The storm rapidly weakened inland and was only a tropical depression later that day. Eventually, Fran curved east-northeastward and transitioned into an extratropical cyclone over Ontario early on September 9.
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.
The 1973 Atlantic hurricane season was the first season to use the Saffir–Simpson hurricane scale, a scale developed in 1971 by Herbert Saffir and Robert Simpson to rate the intensity of tropical cyclones. The season produced 24 tropical and subtropical cyclones, of which only 8 reached storm intensity, 4 became hurricanes, and only 1 reached major hurricane status. Although more active than the 1972 season, 1973 brought few storms of note. Nearly half of the season's storms affected land, one of which resulted in severe damage.
Hurricane Frances was the second most intense tropical cyclone in the Atlantic during 2004 and proved to be very destructive in Florida. It was the sixth named storm, the fourth hurricane, and the third major hurricane of the 2004 Atlantic hurricane season. The system crossed the open Atlantic in late August, moving to the north of the Lesser Antilles while strengthening. Its outer bands struck Puerto Rico and the British Virgin Islands while passing north of the Caribbean Sea. The storm's maximum sustained wind peaked at 145 mph (233 km/h), achieving Category 4 on the Saffir-Simpson Hurricane Scale. As the system's forward motion slowed, the eye passed over San Salvador Island and very close to Cat Island in the Bahamas. Frances was the first hurricane to impact the entire Bahamian archipelago since 1928 and almost completely destroyed their agricultural economy.
Hurricane Cleo was the strongest tropical cyclone of the 1964 Atlantic hurricane season. It was the third named storm, first hurricane, and first major hurricane of the season. Cleo was one of the longest-lived storms of the season. This compact yet powerful hurricane travelled through the Caribbean Sea and later hit Florida before moving offshore Georgia into the Carolinas, killing 156 people and causing roughly $187 million in damages. Major damage was seen as far north as east-central Florida, with the heaviest rains falling along the immediate coast of the Southeast United States into southeast Virginia.
Hurricane Klaus was a minimal Atlantic hurricane that dropped heavy rainfall across the Lesser Antilles in October 1990. The eleventh tropical cyclone and sixth hurricane of the 1990 Atlantic hurricane season, Klaus developed from a tropical wave on October 3 a short distance east of Dominica. It drifted northwestward, and quickly intensified to attain hurricane status on October 5. Though its closest approach to the Lesser Antilles was within 12 miles (19 km), the strongest winds remained to its northeast due to strong wind shear, which caused Klaus to steadily weaken. After deteriorating into a tropical depression, Klaus briefly restrengthened over the Bahamas before dissipating on October 9 under the influence of developing tropical storm, Marco.
The 1898 Atlantic hurricane season ran through the summer and the first half of fall in 1898. The season was fairly active, with 11 storms forming, five of which became hurricanes.
Hurricane Dennis caused flooding in North Carolina and the Mid-Atlantic states in early September 1999, which would later be compounded by Hurricane Floyd. The fifth tropical cyclone of the season, Dennis developed from a tropical wave to the north of Puerto Rico on August 24. Originally a tropical depression, the system moved west-northwestward and strengthened into a tropical storm despite unfavorable wind shear. The storm became a hurricane by August 26. After striking the Abaco Islands, conditions improved, allowing for Dennis to strengthen into a Category 2 on the Saffir–Simpson scale by August 28. Around this time, Dennis began to move parallel to the Southeastern United States. Early on August 30, the storm peaked with winds of 105 mph (165 km/h). By the following day, steering currents collapsed and the storm interacted with a cold front, causing Dennis to move erratically offshore North Carolina. Wind shear and cold air associated with the front weakened Dennis to a tropical storm on September 1 and removed some of its tropical characteristics. Eventually, warmer ocean temperatures caused some re-strengthening. By September 4, Dennis turned northwestward and made landfall in Cape Lookout, North Carolina, as a strong tropical storm. The storm slowly weakened inland, before transitioning into an extratropical cyclone over western New York on September 7.
Tropical Storm Jerry was a tropical storm that caused severe flooding throughout the southeast United States in August of the 1995 Atlantic hurricane season. Jerry, the tenth tropical storm of the season, formed from a tropical wave that moved off the African coast in early August, which organized into a tropical depression and tropical storm between the Bahamas and Florida later in the month, before striking Florida in the latter part of the month. Its remnant circulation persisted until five days after landfall. The rainfall it produced, amounting to over 12 inches (300 mm) in several locations across Florida, Georgia, and South Carolina, was responsible for $40 million (2005 USD) in damage and 6 deaths. At the time, Jerry was the earliest tenth storm to form in a season on record, until Jose in the 2005 season overtook it. Tropical Storm Jerry was also the first tropical cyclone to make landfall in South Florida since Hurricane Andrew in 1992.
Tropical Storm Chris caused minor flooding in the Greater Antilles and the Eastern United States in August 1988. The seventh tropical cyclone and third named storm of the annual hurricane season, Chris developed from a tropical wave while roughly midway between Africa and the Lesser Antilles on August 21. Forming as a tropical depression, it remained weak for several days, crossing the Lesser Antilles, Hispaniola, and The Bahamas during this time. While offshore the coast of Florida on August 28, the depression intensified into Tropical Storm Chris. Thereafter, the system tracked rapidly north-northwestward and came ashore near Savannah, Georgia later that day. Once inland, Chris quickly weakened, and by early on the following day, it weakened to a tropical depression over South Carolina. Six hours later, Chris was absorbed by a cold front while over North Carolina, though the remnants of the system tracked across the Eastern United States and Atlantic Canada before dissipating on August 30.
Tropical Storm Marco was the only tropical cyclone to make landfall on the United States during the 1990 Atlantic hurricane season. The 13th named storm of the season, Marco formed from a cold-core low pressure area along the northern coast of Cuba on October 9, and tracked northwestward through the eastern Gulf of Mexico. With most of its circulation over the western portion of Florida, Tropical Storm Marco produced 65 mph (105 km/h) winds over land. However, it weakened to a tropical depression before moving ashore near Cedar Key. The cyclone combined with a cold front and the remnants of Hurricane Klaus to produce heavy rainfall in Georgia and the Carolinas. After interacting with the nearby Hurricane Lili, Marco continued northward until being absorbed by a cold front on October 13.
Tropical Storm Barry was a rapidly forming tropical cyclone that made landfall on Florida, United States, in early June 2007. The second named storm of the 2007 Atlantic hurricane season, Barry developed from a trough of low pressure in the southeastern Gulf of Mexico on June 1. It tracked rapidly northeastward, reaching peak winds of 60 mph (97 km/h) before weakening and making landfall near Tampa Bay as a tropical depression. Barry quickly lost tropical characteristics after wind shear removed much of the convection, and early on June 3, it completed the transition into an extratropical cyclone. The extratropical remnants tracked up the East Coast of the United States, and were absorbed by a larger extratropical cyclone on June 5.
The 1924 Atlantic hurricane season featured the first officially recorded Category 5 hurricane, a tropical cyclone with maximum sustained winds exceeding 155 mph (249 km/h) on the modern-day Saffir–Simpson scale. The first system, Tropical Storm One, was first detected in the northwestern Caribbean Sea on June 18. The final system, an unnumbered tropical depression, dissipated on November 24. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Of the 13 tropical cyclones of the season, six existed simultaneously. The season was average with 11 tropical storms, five of which strengthened into hurricanes. Further, two of those five intensified into major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale.
Hurricane Hanna was a moderately powerful but deadly tropical cyclone that caused extensive damage across the Western Atlantic, particularly in the Turks and Caicos Islands and the East Coast of the United States. The eighth named storm and fourth hurricane of the 2008 Atlantic hurricane season. It formed east-northeast of the northern Leeward Islands on August 28. Initially, the storm struggled to intensify due to moderate wind shear as it moved westwards towards the Bahamas. By August 31, Hanna had drifted southwards and began intensifying while over the Bahamas; it attained its peak intensity as a Category 1 hurricane while over the Turks and Caicos Islands. Due to the outflow of the nearby Hurricane Gustav, Hanna weakened back into a tropical storm the next day as it began to drift northwestwards towards the Southeastern United States. The storm struck Myrtle Beach, South Carolina, before moving up the Eastern Seaboard to become an extratropical cyclone as it moved by New England into Atlantic Canada early on September 7. The system raced across the North Atlantic, sweeping west of Great Britain on September 10 before turning north and becoming absorbed by a stronger extratropical cyclone between Iceland and Greenland late on September 12.
Tropical Storm Dottie was the ninth tropical cyclone and fourth named storm of the 1976 Atlantic hurricane season. The precursor to Dottie formed in the Gulf of Mexico on August 17 and organized into a tropical depression on August 18. The storm drifted towards the east, and, after peaking as a moderate tropical storm, it accelerated northeastward and made landfall on Florida. Upon re-emerging in the Atlantic, Dottie turned northward and moved ashore near Charleston, South Carolina. Damage from the storm was primarily insignificant and limited to gusty winds, heavy rainfall, and high tides; however, a fishing boat capsized in the Bahamas, resulting in the deaths of four people.
Subtropical Storm Four brushed Florida and The Bahamas in October 1974. The eighteenth cyclone and fourth subtropical storm of the 1974 Atlantic hurricane season, the storm developed near eastern Cuba on October 4 from an area of disturbed weather. Shortly before striking Andros Island on October 6, the system strengthened into a subtropical storm. The storm made its closest approach to Florida early on October 7. Peaking with sustained winds of 50 mph (85 km/h), the system veered northward and then northeastward, but nonetheless caused heavy rainfall and coastal flooding on land in Florida. While paralleling offshore North Carolina and South Carolina, the storm began to slowly weaken. By late on October 8, the subtropical cyclone merged with a cold front while well east of Cape Hatteras.
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.
