[1] Before the season started, the United States Weather Bureau office in Miami began setting up a teleprinter to distribute hourly advisories to newspapers and the American Red Cross.

[4] Utilizing radars along the East Coast of the United States, the Weather Bureau tracked both Hurricanes Daisy and Helene for 575 mi (925 km), which was the first such occurrence of that feat.

[7] A small circulation crossed Panama from the Pacific Ocean on May 17, and by the following day it was a developing depression near San Andrés in the western Caribbean.

The system gradually organized over warm waters while moving to the northwest, developing a well-defined low pressure area by May 23 as it approached western Cuba.

As it moved ashore, Alma produced a high tide of 2.9 ft (0.88 m) along Padre Island, and one person drowned near Galveston due to heavy surf.

[12] At 0400 UTC on August 12, the San Juan Weather Bureau office initiated advisories on Tropical Storm Becky about halfway between the Lesser Antilles and Cape Verde.

[12] A weak trough near 50° W allowed the hurricane to turn to the north, and Cleo continued to intensify, based on improved definition of the eye on radar imagery.

Originally winds were thought to be higher in Cleo, at 160 mph (260 km/h), which would make it a Category 5 hurricane, but reanalysis later on determined it to be weaker.

[1] On August 24, a nearby ship reported a low pressure area and strong winds, indicating the formation of a small tropical cyclone near the Bahamas.

[21] After a Hurricane Hunters flight indicated winds of 55 mph (89 km/h), the Weather Bureau initiated advisories on Tropical Storm Daisy early on August 25 to the north of the Bahamas.

[1] By early August 28, the hurricane reached peak winds of 130 mph (210 km/h),[21] and a minimum pressure of 948 mbar (28.0 inHg) while offshore South Carolina.

Passing east of Hatteras, Daisy dropped moderate rainfall, peaking at 5.92 in (150 mm) near Morehead City, North Carolina,[23] before turning to the northeast on August 29.

The Weather Bureau issued a hurricane warning from Block Island to Provincetown, Massachusetts, due to the projected path near New England.

[1] After affecting Haiti, Ella weakened to a Category 1 hurricane before moving ashore in southeastern Cuba early on September 2.

At its final landfall, the storm produced 13.6 in (350 mm) of rainfall in Galveston, Texas, and in the city, one person died after falling overboard a boat.

That day, Hurricane Hunters observed 55 mph (89 km/h) winds, which prompted the Weather Bureau to upgrade it to Tropical Storm Fifi.

[1] Due to the storm's fast track to the northwest, a gale warning and hurricane watch were issued for the Leeward and northern Windward Islands.

[27] On September 6, Fifi intensified into a hurricane and reached peak winds of 85 mph (137 km/h), around the same time that it passed about 150 mi (240 km) northeast of the Leeward Islands.

It moved westward, and based on surface reports from the island chain, a tropical depression developed west of Martinique on September 13.

[12] The Hurricane Hunters encountered winds of 70 mph (110 km/h) on September 14 just offshore the Dominican Republic; on that basis the system was designated Tropical Storm Gerda.

The high terrain of Hispaniola quickly weakened Gerda, and on September 15 the Hurricane Hunters could not detect a closed circulation.

Aided by an approaching trough, a small low pressure area redeveloped on September 19, which struck southern Texas and moved to the northeast.

On September 21, the Hurricane Hunters observed a circulation, which indicated a tropical depression had formed east of the northern Leeward Islands.

[12] While paralleling the southeastern United States, Helene produced a peak storm surge of 6 ft (1.8 m) near Marine Corps Air Station Cherry Point in North Carolina.

[35] On September 24, ship reports near an area of disturbed weather east of the Lesser Antilles prompted a Hurricane Hunters flight.

By the time the aircraft investigated the system, they discovered a tropical storm with winds of 40 mph (64 km/h), which was named Ilsa by the Weather Bureau.

An eastward-moving cold front turned the storm to the north and northeast, and Janice crossed central Cuba early on October 6.

On October 9, the hurricane turned to the east-northeast, and by that time had weakened slightly; however, the next day it re-attained its previous peak intensity while passing northwest of Bermuda, reaching a minimum pressure of 968 mbar (28.6 inHg).

[38] When Janice was still over Cuba, the Weather Bureau issued gale warnings from Vero Beach, Florida, to Cape Hatteras, North Carolina.

[1] A low pressure area developed north of Hispaniola from a dissipating cold front, organizing into a tropical depression on October 15.
