1975 Atlantic hurricane season

The 1975 Atlantic hurricane season featured the first tropical storm to be upgraded to hurricane status using only satellite imagery. In terms of activity, the 1975 season was near average, with nine named storms forming, of which six became hurricanes. Three of those six became major hurricanes, which are Category 3 intensity or higher on the Saffir–Simpson scale. 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 Ocean.

Season summary
The Atlantic hurricane season officially began on June 1, with the first tropical cyclone developing on June 24. Although 23 tropical depressions developed, only nine of them reached tropical storm intensity; this was near normal compared to the 1950–2000 average of 9.6 named storms. Six of these reached hurricane status, slightly above the 1950–2000 average of 5.9. The Atlantic hurricane season officially ended on November 30, == Systems ==
Systems
Tropical Storm Amy Tropical Storm Amy originated from a weak trough on June 24 accompanied by scattered showers and thunderstorms over Florida. The system tracked westward in response to an upper-tropospheric low over Georgia. By June 26, a surface circulation developed north of the Bahamas and satellite imagery showed a significant increase in convective activity and the National Hurricane Center (NHC) classified the system as a tropical depression early on June 27. On June 28, the system attained tropical storm-status while tracking north-northeast off the coast of North Carolina. By June 29, a trough, moving through the westerlies, rapidly approached the storm, causing the newly designated Amy to turn sharply toward the east. Strong wind shear disorganized the system slightly, leading to Amy featuring subtropical characteristics. By the evening, the strongest winds were not located around the center, but were instead situated between 60 and 90 mi (95 and 140 km) from the center. Convection became displaced from the center of circulation but the storm continued to intensify. Over the following several days, Amy tracked generally northeastward but underwent eastward jogs in response to rapidly moving troughs to the north. Amy neared hurricane intensity several times, beginning on June 30 as maximum winds increased to 70 mph (110 km/h); however, the storm was unable to acquire enough tropical features, and remained predominately subtropical. As a tropical depression, Amy produced scattered rainfall in Florida, peaking around near the Georgia border. Along the North Carolina coast, heavy rain fell as the center of Amy tracked nearby. Many coastal areas recorded more than with a peak amount of falling in Belhaven, North Carolina. Rough seas from the storm resulted in minor coastal flooding and beach erosion in North Carolina and Virginia. Small craft advisories were issued along the Virginia and North Carolina coastlines as waves up to affected the region. Several beaches were closed due to the rough conditions. In Hampton, Virginia, a funnel cloud spawned by a squall line associated with Amy formed just offshore. On June 30, schooner capsized in rough seas roughly 250 mi (400 km) east of Cape Hatteras, North Carolina, carrying a family of four people. The father, a diabetic, slipped into a coma and died after he was unable to find his insulin pen. The three kids were rescued on July 14. Hurricane Blanche A tropical wave emerged into the Atlantic Ocean from the west coast of Africa on July 14. The system remained weak for about a week, before convection began increasing significantly on July 21. After wind shear decreased, The strong winds knocked over two mobile homes and destroyed a slaughterhouse, which was under construction. Additionally, trees and power lines were downed, leaving between 500 and 1,000 customers without electricity. The electrical corporation in Nova Scotia suffered about $196,600 in damage. Telephone services were also interrupted. The A. Murray MacKay Bridge was closed after an oil rig broke loose and threatened to strike the bridge. In Prince Edward Island, flights to and from the Charlottetown Airport were canceled, as was ferry service to Nova Scotia. In the province, many homes and businesses lost telephone service. Overall, damage in Canada reached about $6.2 million. Tropical Depression Six Tropical Depression Six developed from a trough of low pressure in the northeastern Gulf of Mexico about southwest of Cape San Blas, Florida, on July 27. The tropical depression dropped heavy rainfall, with some areas of the Florida Panhandle experiencing more than of precipitation, with a maximum total of observed in DeFuniak Springs. Bay, Gulf, Holmes, Okaloosa, Santa Rosa, Wakulla, and Walton were hardest hit. Numerous roads were flooded and closed, with $3.2 million in damage to that infrastructure. About 500 homes suffered flood damage, 22 of which were destroyed. Damage is estimated to have reached $8.5 million in the state of Florida alone. In southern Alabama, overflowing rivers flooded several businesses and homes in Brewton and East Brewton. Damage in Alabama totaled approximately $300,000. In Mississippi, about 50 families in the vicinity of the Biloxi River were evacuated as the river threatened to exceed its banks, The storm left three fatalities, with two in Florida and one in Alabama. Hurricane Caroline A tropical wave exited the west coast of Africa on August 15 and rapidly moved westward. On August 24, the system developed into a tropical depression near the southeastern Bahamas. Soon after, it crossed Cuba and degenerated back into a tropical wave. The system redeveloped into a tropical depression on August 27 as it continued westward into the Gulf of Mexico. Passing just north of the Yucatán Peninsula, the depression strengthened into Tropical Storm Caroline on August 29. The storm slowed quickly attained hurricane status as it approached land. Two National Oceanic and Atmospheric Administration (NOAA) planes conducted experiments to study the environment and winds in and around the eye. Caroline intensified further into a major hurricane, with peak winds of and a minimum pressure of . On August 31, Caroline made landfall in a rural area of Tamaulipas in northeast Mexico, about south of Brownsville. Caroline rapidly weakened to a tropical depression twelve hours after landfall and dissipated on September 1 over northeastern Mexico. Ahead of Caroline's landfall, hundreds of people in Mexico evacuated to shelters. Along the Mexican coast, Caroline produced storm tides, causing significant damage to several small villages. Portions of south Texas also experienced heavy rainfall, with at Port Isabel. Brownsville broke a record for the highest amount of precipitation observed on a day in August. Two deaths occurred from drowning in Galveston. Hurricane Doris A low pressure area developed within a frontal band over the central Atlantic on August 27. via the Dvorak technique. Thousands of people in these areas became homeless as flood waters submerged numerous communities. As Eloise progressed westward, it affected Cuba to a lesser extent. In advance of the storm, about 100,000 residents evacuated from the Gulf Coast region. In that region, an additional 17 people died as a result of freshwater flooding from the post-tropical storm; Up to of rain fell in Bermuda from the hurricane. Already severely impacted by flooding from Eloise days earlier, New England prepared for additional flooding from Faye. The National Weather Service issued flash flood watches, resulting in more evacuations. At 00:00 UTC on September 27, the hurricane reached its maximum sustained wind speed of . Later that day, Faye curved northeast under strong westerly flow. While over the Atlantic Ocean, a National Oceanic and Atmospheric Administration (NOAA) C-130 hurricane hunter aircraft flew into Gladys on October 1 on a research mission. The mission was to study the storm and use the information to improve seeding operations for the now-defunct Project Stormfury. A hurricane watch was issued for North Carolina's Outer Banks on October 1, extending from Cape Lookout to Kitty Hawk. Residents along the Outer Banks evacuated to hotels in Elizabeth City, and four United States Coast Guard servicemen stationed at a lighthouse in Cape Hatteras were evacuated. While passing the Outer Banks, a campground and road was closed due to waves. Tropical Depression Eighteen A tropical depression developed in the southern Gulf of Mexico about northwest of Campeche City in Mexico on October 14. Moving around the western periphery of a subtropical ridge, the depression intensified while moving northeast towards the central Gulf Coast of the United States due to an advancing cold front. Tropical Storm Hallie A frontal trough exited the East Coast of the United States on October 18. The southern portion of the system became stationary near the Bahamas; simultaneously, a cut-off upper-level low formed in the same region. The disturbance produced scattered convection, until a tropical wave merged with it on October 23. The system developed into a subtropical depression by October 24, while located about east of Florida. The depression drifted northward on October 25 and eventually acquired tropical characteristics by October 26. Due to tropical storm force winds, the system was reclassified as Tropical Storm Hallie, while situated about east of Charleston, South Carolina. Hallie accelerated to the northeast starting on October 26. By the following day, Hallie peaked with winds of . Later that day, Hallie merged with a frontal zone and became extratropical offshore Virginia. The precursor to Hallie produced extensive cloudiness precipitation in the Bahamas. On October 27, gale warnings were issued for portions of the Outer Banks of North Carolina, and small craft advisories were posted for coastal areas from Georgia to Virginia. Tides along the North Carolina and Virginia coasts were generally between above normal. Generally light precipitation fell, peaking at in Manteo, North Carolina. Forecasters anticipated the depression would intensify into a tropical storm before landfall. A reconnaissance mission into the cyclone found winds; however, due to the interaction with land, the NHC did not upgrade the depression. Not long after forming, the depression struck Tampico, Tamaulipas. A barometric pressure of was recorded in the city, along with sustained winds of . The system was no longer monitored by the NHC after landfall and quickly dissipated on July 26. On September 3, two tropical depressions developed near Cabo Verde. The westernmost, designated Tropical Depression Nine, tracked generally westward and eventually dissipated near the Lesser Antilles on September 9. The easternmost, Tropical Depression Ten, also moved westward and dissipated on September 6. Short-lived Tropical Depression Eleven developed that same day over the Gulf of Mexico, then degenerated the next. Tropical Depression Twelve developed near Bermuda on September 11. Initially, the depression drifted northeastward but later accelerated and dissipated by September 14. Tropical Depression Sixteen developed near the Gulf of Honduras on September 25 and tracked slowly westward. By September 28, the depression made landfall in northern Belize before dissipating two days later. Tropical Depression Seventeen developed to the west of the Canary Islands on October 3, moving northwestward and then northeastward before dissipating southwest of the Azores on October 5. Tropical Depression Twenty formed on October 27 over the southwestern Caribbean Sea and tracked northwest. After turning nearly due west, the depression briefly made landfall near the NicaraguaHonduras border and made another landfall in southern Belize shortly before dissipating on October 29. On November 8, Tropical Depression Twenty-One developed off the coast of Honduras. Moving north-northwestward, the system gradually intensified. Between November 9 and 10, reconnaissance missions into the depression found winds of ; however, the NHC did not upgrade it to a tropical storm, because weaken occurred shortly thereafter. Over the following few days, the system gradually turned southward and made landfall in the southwestern edge of the Yucatán Peninsula on November 12, shortly before dissipating. In late November, Tropical Depression Twenty-Two formed over the central Atlantic. A short-lived system, it formed on November 29 and dissipated on December 1. == Storm names ==
Storm names
The following list of names was used for named storms that formed in the North Atlantic in 1975. Storms were named Amy, Caroline, Doris, Eloise, and Faye for the first (and in the case of Eloise, only) time in 1975. Retirement On account of severe damage associated with the storm, the name Eloise was later retired. Due to the naming lists changing in 1979, no replacement name was selected. == Season effects ==
