[3] 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.
Hurricane Gloria, the strongest storm of the season, resulted in 14 fatalities and about $900 million (1985 USD) in damage in North Carolina, Virginia, the Mid-Atlantic, and New England.
Three other tropical cyclones – Hurricanes Bob, Danny, and Kate – caused moderate to extensive damage in Cuba and the United States.
While crossing Florida, Bob curved sharply northward and emerged into the Atlantic Ocean near Vero Beach early on July 24.
The system moved eastward and entered the Atlantic Ocean, where it transitioned into a low-pressure area offshore Georgia on August 9.
As the storm passed north of Bermuda late on August 12, minor effects were reported, with sustained winds reaching 28 mph (45 km/h) and rainfall up to 0.61 in (15 mm).
At 1620 UTC on August 16, Danny attained its peak intensity with winds of 90 mph (145 km/h) and a minimum barometric pressure of 988 mbar (29.2 inHg).
[31] A combination of rainfall and storm surge in southern Mississippi caused severe beach erosion and flooded 70 homes in Hancock County alone.
After becoming a Category 2 hurricane, the storm veered east-northeastward and missed the central portions of the Gulf Coast of the United States.
[34] It continued to intensify and early on the following day, Elena peaked with maximum sustained winds of 125 mph (200 km/h) and a minimum barometric pressure of 953 mbar (28.1 inHg).
[35] About 1 million fled the coast as Elena approached, with some people undergoing two emergency evacuations due to the erratic path of the storm.
[39] Elena also dropped heavy rain in the Big Bend area, where precipitation peaked at 15.67 in (398 mm) in Cross City.
[40][41][42] Despite landfall in Mississippi as a Category 3 hurricane, sustained winds in the state only reached 91 mph (146 km/h), recorded in Harrison County, Ocean Springs, and Pascagoula.
[45] In addition, there were nine total fatalities, including two in Texas from storm-induced rip currents; this was considered a low number, most likely the result of the massive evacuations prior to landfall.
At 1800 UTC on September 15, Tropical Depression Seven formed about 150 mi (240 km) north-northeast of Cockburn Town, Turks and Caicos Islands.
It is estimated that the depression strengthened into Tropical Storm Fabian at 1800 UTC on September 16, which was when a reconnaissance aircraft reported an atmospheric pressure of 1,004 mbar (29.6 inHg).
Fabian strengthened further and at 0945 UTC on that day, the storm attained its peak intensity with winds of 65 mph (105 km/h) and a minimum atmospheric pressure of 992 mbar (29.3 inHg).
[53] At 0120 UTC on September 25, Gloria attained its peak intensity with maximum sustained winds of 145 mph (235 km/h) and a minimum barometric pressure of 919 mbar (27.1 inHg).
Thousands of trees were knocked over, which struck power lines, leaving about 1.5 million people – roughly two-thirds of Long Island – without electricity.
[9][56] A trough of low pressure located near dissipating Tropical Storm Fabian developed a circulation on September 18 and then began to drift northward.
Shortly thereafter, Henri attained its peak intensity with maximum sustained winds of 60 mph (95 km/h) and a minimum atmospheric pressure of 996 mbar (29.4 inHg).
[60] It entered the Caribbean on October 5 and produced torrential rainfall across Puerto Rico; the floods killed 180 people, mostly from a mudslide near Ponce.
The storm began to execute another cyclonic loop, reaching the Lafayette area before curving back out to the Gulf of Mexico on October 30.
[64] Juan produced large waves at oil rigs in the Gulf of Mexico, causing several damaged platforms, vessels, and killed nine people.
The erratic motion of the storm offshore and inland over Louisiana resulted in heavy rainfall, peaking at 17.78 inches (452 mm) in Galliano.
It crossed the Southeastern United States and emerged into the Atlantic Ocean near Cape Fear, North Carolina on November 23.
[71] Further north in the Florida Panhandle, strong winds also resulted in numerous power outages, including in Tallahassee, where 90% of the city was left without electricity.
Eventually, the depression began disorganizing, with convection stretching across Hispaniola, Puerto Rico, and the Leeward Islands on September 14, despite the center being located south of Jamaica.
Later that day, a reconnaissance aircraft did not indicate a circulation; thus, the depression dissipated while located about 195 mi (315 km) south of Kingston, Jamaica on September 14.
