Tropical Depression One By June 11, an upper-level low caused thunderstorm development off the Florida coast, which caused the formation of a tropical depression. Moving westward, the depression moved into St. Augustine, causing a total of of rainfall at
Jacksonville Beach, Florida, as its main thunderstorm activity was concentrated north of the center. It dissipated as a tropical cyclone on June 14 while moving through the Florida panhandle. The small remnant low continued moving westward inland of the Gulf coast, causing occasional redevelopment of thunderstorm activity as the system moved into Louisiana, before both the thunderstorm activity and low-pressure area dissipated by June 17.
Tropical Depression Two An upper-level low-pressure area traversing the southern Gulf of Mexico spawned convective activity over the
Isthmus of Tehuantepec on June 16. This convective area waxed and waned somewhat in intensity, until becoming a larger disturbance on June 18. A surface low soon formed, and around 12:00 UTC that day, the system developed into a tropical depression over the
Bay of Campeche. With vertical wind shear preventing significant further intensification,
Barbados recorded up to of rainfall in association with the system. The depression entered the Caribbean Sea and failed to intensify further, dissipating about halfway between the
Dominican Republic and
Venezuela late on July 26.
Subtropical Storm One A weak frontal trough generated a low-pressure system that organized into a
subtropical depression north of
Bermuda on August 18. The depression headed northeast and strengthened to a subtropical storm. It is believed to have merged with a front on August 21. The history of Subtropical Storm One is not entirely certain, as satellite images were largely unavailable due to a failure of the VISSR unit on GOES EAST (then
GOES-5), and this system remained at the fringe of the GOES WEST and
Meteosat throughout its existence. Wind gusts up to were reported on the southwest coast of
Newfoundland. In addition, a weather office on the island reported rainfall at .
Tropical Storm Arthur A well-defined tropical wave emerged into the Atlantic from the west coast of Africa on August 23. Moving westward and later northwestward, the system remained to the south of a persistent shearing pattern that inhibited the development of several tropical waves. A reconnaissance aircraft flight indicated that a tropical depression formed late on August 28 roughly east of
Trinidad. On the next day, another reconnaissance flight recorded tropical storm conditions, and thus, the depression intensified into Tropical Storm Arthur. The cyclone attained its peak intensity several hours later with maximum sustained winds of 50 mph (85 km/h) and a minimum barometric pressure of . Arthur was downgraded to a depression on September 1 after being negatively impacted by vertical
wind shear, and dissipated on September 5 about halfway between the Bahamas and Bermuda. Despite its close proximity to the Lesser Antilles, Arthur caused no significant impact on land as it was a tropical depression at the time.
Tropical Storm Bertha On August 26, a tropical wave emerged into the Atlantic from the west coast of Africa. Tracking westward, the wave developed into a tropical depression about west-southwest of the southwesternmost islands of Cabo Verde and in close proximity to the east of Arthur. A reconnaissance flight into the depression on August 31 indicated that it strengthened into Tropical Storm Bertha. Later that day, Bertha peaked as a minimal tropical storm with maximum sustained winds of 40 mph (65 km/h) and a minimum barometric pressure of . The system moved northwestward due to a weakening high pressure ridge to the north. Based on observations from reconnaissance flights on September 1, Bertha was downgraded to a tropical depression. On September 2, Bertha turned north-northeastward into response to an approaching cold front. The cold front then eroded the high pressure ridge, causing the cyclone to accelerate northeastward. Bertha later merged with the cold front on September 4. the system organized into a subtropical depression early on August 31 approximately northwest of Bermuda. Based on a ship report of sustained winds of 40 mph (65 km/h), the subtropical depression transitioned into a tropical system and intensified into a tropical storm, receiving the name Cesar. By September 6, the disturbance had emerged into the southwest Gulf of Mexico and consolidated into a smaller system which had enough organization to be classified as a tropical depression, the seventh of the season. The depression moved north-northwest into northeast Mexico on the afternoon of September 7, dissipating completely on September 8. Heavy rains fell over parts of Mexico, with a peak total of in
Chicontepec de Tejeda,
Veracruz.
Hurricane Diana On September 8, an extratropical cyclone organized into Tropical Storm Diana north of
the Bahamas. Diana proved difficult for meteorologists to forecast, initially moving westward towards
Cape Canaveral, but then turned to the north and paralleled the coastline. On September 11, the storm reached hurricane strength, and continued to intensify to a
Category 4 hurricane, peaking with maximum sustained winds of 130 mph (215 km/h) and a minimum barometric pressure of . Diana moved north-northeast, and performed a small anti-cyclonic loop before striking near
Cape Fear, North Carolina, as a minimal Category 2 hurricane on September 13. A weakened Diana curved back out to sea and headed northeast until it became extratropical near Newfoundland on September 16. Severe beach erosion impacted
Horry County, South Carolina, damaging 90 residences, 40 multi-family dwellings, 8 mobile homes, and a few businesses. Many areas in southeastern North Carolina reported freshwater flooding, with parts of
Duplin,
Pender, and
Sampson counties experiencing
100-year flood events. High winds damaged some buildings and homes, especially in coastal areas of
Brunswick and
New Hanover counties. Throughout the state, Diana destroyed 68 homes and substantially damaged 325 others. Damage estimates were set at $65.5 million, Diana became the first hurricane to strike a nuclear power plant — the
Brunswick Nuclear Generating Station, which recorded sustained hurricane-force winds but no damage to the facility.
Tropical Storm Edouard The origins of Tropical Storm Edouard are unclear, but an area of persistent organized storms existed over the Gulf of Mexico for six or seven days prior to September 14 after a frontal system weakened. A tropical wave that crossed Central America on September 9 also enhanced convection. Based on a reconnaissance aircraft investigation, a tropical depression formed at 00:00 UTC on September 14 about east-southeast of
Tecolutla, Veracruz.
Tropical Storm Fran On September 14, a well-defined tropical wave exited the coast of Africa. The next day, it had rapidly organized into a tropical depression. and it was given the name Fran. It turned to the northwest, and passed very near the Cabo Verde Islands. Fran moved northwest to west-northwest on September 17–18 as it continued to organize. During this period satellite imagery indicated that Fran peaked with maximum sustained winds of and a minimum surface pressure of . Between September 19 and September 20, the cyclone turned westward and encountered strong
upper-level wind shear, which caused Fran to dissipate on September 20. Damage totaled approximately $2.84 million and 29-32 people died in the Cabo Verde Islands, making it the country's second-deadliest cyclone, behind only
Hurricane Debbie in 1961. then situated about south of Bermuda. The depression drifted northward due to an approaching cold front and passed near Bermuda late on September 17. About 24 hours later, a reconnaissance flight observed a barometric pressure of and a ship recorded sustained winds of 45 mph (70 km/h), leading the depression to be upgraded to Tropical Storm Gustav, Twelve hours after reaching hurricane status, Hortense began a sharp weakening trend while passing east of Bermuda. By September 27 it was a minimal tropical storm, and subsequently it executed a clockwise loop to the southwest. The intensity of Hortense fluctuated slightly over the subsequent few days, although it never regained its former intensity. On September 30, after turning to the west and later to the north, the storm passed just west of Bermuda. As the storm was so weak, the island only reported winds of .
Tropical Storm Isidore On September 24, a disturbance formed along the western periphery of a semi-stationary frontal zone close to the Bahamas. This disturbance developed into a tropical depression around 12:00 UTC on September 25 near
Samana Cay. Moving generally west-northwestward, the depression intensified into Tropical Storm Isidore about 24 hours later and passed near or over several Bahamian islands. Early on September 27, Isidore attained its lowest barometric pressure of near
Andros, shortly before peaking with sustained winds of 60 mph (95 km/h). Just after 1200 UTC that day, the cyclone made landfall near
Jupiter, Florida. Retaining tropical storm strength, Isidore curved northeastward, emerging over water near Jacksonville, Florida. The system was absorbed by a front on October 1 about northeast of Bermuda. Isidore produced heavy rains in the Bahamas, but no serious damage. High tides along the east coast of Florida caused beach erosion, damaged segments of
State Road A1A, and damaged or destroyed sea turtle nests. Winds mainly only caused scattered power outages. However, one person died near
Orlando after a live wire fell on his pickup truck. Total damages in Florida were estimated at over $750,000.
Hurricane Josephine In early October, an old frontal trough interacted with an upper-level low north of
Hispaniola, The subtropical depression intensified and transitioned into Tropical Storm Josephine on October 8. The storm intensified into a hurricane on October 10 and peaked as a Category 2 hurricane with winds of 105 mph (165 km/h) on October 12. Moving generally northward, Josephine briefly jogged to the west, Offshore, a sailboat with six crewmen on it became disabled due to high waves, estimated to have exceeded , produced by the hurricane. All of the people on the ship were quickly rescued after issuing a distress signal by a nearby tanker vessel. In
Massachusetts, one man drowned after falling off his boat on the North River amidst large swells produced by the storm. In
Long Island, New York and parts of
New Jersey, tides between above normal resulted in minor
coastal flooding.
October Tropical Depression This system was recognized as the seventeenth tropical depression of the season by the National Hurricane Center after the season ended. A retrograding
upper-level low spurred the development of a low east of the Bahamas on October 25. The system tracked westward with limited shower and thunderstorm activity, crossing Florida on October 26 before moving into the Gulf of Mexico. Once the system moved into the north-central Gulf, deep convection began to develop near its center, expanding in intensity and coverage near and after landfall in extreme southeast Mississippi. The small system accelerated rapidly to the north and northeast ahead of an approaching cold front, moving across the Tennessee Valley and central Appalachians before linking up with the front and becoming a weak extratropical cyclone. The non-tropical cyclone then moved through coastal New England. The depression dropped rains across the eastern United States, though precipitation peaked at near
Pascagoula, Mississippi. The hurricane's barometric pressure decreased to on November 11, before becoming extratropical over cooler waters two days later, then situated about southeast of
Cape Race, Newfoundland. The storm dropped heavy rainfall in Puerto Rico, causing numerous landslides, drowning one person, and damaging some homes and crops. Heavy damage occurred in the
British Virgin Islands, totaling $152 million, while the
United States Virgin Islands had about $3 million in damage. including one that developed into a tropical depression at 12:00 UTC on November 23 about 35 mi (55 km/h) east of
Boynton Beach, Florida. The depression crossed the northern Bahamas and then moved out to sea, dissipating about east of Bermuda on November 28. There has been evidence that the November storm may have become a
subtropical cyclone east of Bermuda. The cyclone contributed to the formation of a potent
nor'easter. Strong winds and abnormally high tides impacted the east coast of Florida from
North Miami Beach to
Fernandina Beach. and at least 600 people were ordered to evacuate due to erosion. Heavy rains also fell, with
West Palm Beach recording on November 22, a record for that calendar day. About 100 people evacuated from low-lying areas in
Palm Beach County.
Hurricane Lili In the second week of December, a frontal trough stalled south of Bermuda. An upper-level disturbance moved over the area on December 9, and produced widespread convection along the frontal wave. The system moved to the northeast, and based on a developing circulation within the convection, the NHC classified it as a subtropical cyclone on December 12 while located northeast of Bermuda. A day later, a ridge forced the storm to the southeast and later to the south for a few days. A break in the ridge allowed the storm to turn back to the northeast on December 16, followed by a turn northwestward a day later. Another ridge halted the storm's movement, turning it back to the southwest on December 18, and later to the south. During this time, the subtropical storm intensified, with satellite-estimated hurricane-force winds by December 19. On the next day, a nearby ship recorded winds of 72 mph (117 km/h), along with a minimum pressure of . Based on the observations, Lili was only one of six Atlantic hurricanes on record during the month of December. After becoming a tropical cyclone, Lili accelerated to the southwest, completing a large cyclonic loop by December 22, after crossing over the same location one week prior. That day, a hurricane watch was issued for Puerto Rico and the
Virgin Islands on December 22. However, Lili weakened due to increased wind shear, degrading to a tropical storm on December 23 while northeast of
Antigua. The storm rapidly lost organization as it approached the Leeward Islands, dissipating near the northern coast of the Dominican Republic on December 24. The storm brought light rainfall to the region. ==Storm names==
