Drifting slowly and executing a cyclonic loop, Flora dropped very heavy rainfall in the Greater Antilles, including over 100 in (2,500 mm) in Cuba.

In October, Hurricane Ginny moved erratically offshore the Southeastern United States, though eventually, the extratropical remnants struck Nova Scotia.

[4] Early in the season, activity was suppressed by an abnormally intense trough offshore the East Coast of the United States as well as strong westerly winds.

Flora was the most intense tropical cyclone of the season, peaking as a Category 4 hurricane with winds of 150 mph (240 km/h) and a minimum barometric pressure of 933 mbar (27.55 inHg).

[2] Based on ship data and reconnaissance aircraft flights being unable to locate a circulation, Arlene degenerated into a trough about 24 hours later.

Arlene weakened and lost tropical characteristics as it continued northeastward, becoming extratropical early on August 11 about 300 mi (485 km) southeast of Cape Race, Newfoundland.

[5]: 130  The storm had its greatest impact on Bermuda, where high winds and near-record rainfall of 6.05 in (154 mm) downed trees, power lines, and caused flooding.

[7]: 182  The system organized into a tropical depression early on August 20 about 540 mi (870 km) northeast of Cayenne, French Guiana.

[5]: 130  Based on another reconnaissance flight on August 22 observing a barometric pressure of 977 mbar (28.9 inHg), Beulah intensified into a hurricane around 18:00 UTC.

[7]: 186  The storm intensified into a Category 3 hurricane by early on August 24, at which time Beulah attained its peak intensity with maximum sustained winds of 120 mph (195 km/h) and a minimum barometric pressure of 958 mbar (28.29 inHg).

[5]: 131 Early on August 25, Beulah weakened significantly due to unfavorable conditions caused by an anticyclone to its south,[5]: 131  falling to Category 1 intensity.

[2] Early on August 26, the hurricane turned northeastward under the influence of an upper-level trough offshore the East Coast of the United States.

Drifting northward,[5]: 131  the system developed tropical depression by 12:00 UTC on September 9, while situated about 355 mi (570 km) northeast of Turks and Caicos Islands.

The cyclone intensified further and reached hurricane status early on September 12, peaking with maximum sustained winds of 80 mph (130 km/h) and a minimum barometric pressure of 990 mbar (29.23 inHg).

Around 12:00 UTC on September 14,[2] the storm was absorbed by a large extratropical cyclone while located about 725 mi (1,167 km) north-northwest of Corvo Island in the Azores.

[5]: 131  The system developed into Tropical Storm Cindy at 12:00 UTC on September 16, while located about 210 mi (340 km) south of Cameron, Louisiana.

The system continued weakening and dissipated late on September 24, while located about halfway between Bermuda and Flores Island in the Azores.

[2] An Intertropical Convergence Zone (ITCZ) disturbance developed into a tropical depression while east of the Windward Islands on September 23.

Edith then turned northwestward and briefly became a hurricane again, but weakened to a tropical storm before making landfall near La Romana, Dominican Republic, at 10:00 UTC the next day.

[7]: 219 In Martinique, a wind gust of 127 mph (204 km/h) was observed at Le Lamentin Airport; tides about 8 ft (2.4 m) above normal and heavy rainfall impacted the island.

[5]: 133  In Puerto Rico, the storm brought heavy rainfall to the southwest corner of the island and abnormally high tides to the south coast.

Flora gradually lost convection and became extratropical on October 12 while located 270 mi (430 km) east-southeast of Cape Race, Newfoundland.

The next day, Ginny attained hurricane status,[2] and approached North Carolina before looping to the southwest due to a ridge over New England.

[5]: 136 [24]: 32  Ahead of an advancing trough,[25] Ginny turned sharply northward and later northeastward, paralleling the coast of the Southeastern United States.

Moving farther offshore, Ginny gradually intensified and peaked with maximum sustained winds of 110 mph (175 km/h) late on October 28.

[29]: 14  During its passage, the storm brought an influx of cold air that produced up to 4 ft (1.2 m) of snow in northern Maine, killing two people.

[5]: 138  On October 25, the wave spawned a tropical depression,[2] based on ship and reconnaissance flights reports of southwest winds and heavy rainfall.

[2] Around this time, the storm developed an intense rainband that produced winds of 58 mph (93 km/h), as measured by reconnaissance aircraft between Dominica and Guadeloupe.

[2] The threat of Helena prompted the San Juan Weather Bureau to issue a hurricane watch and later gale warnings for portions of the Lesser Antilles.

The remnants of the depression became extratropical and moved rapidly northeastward, crossing Florida on September 29 and then dissipating offshore the Northeastern United States by October 1.
