In 2012, as part of the Atlantic hurricane reanalysis project, meteorologists identified two previously unknown September tropical storms and fine-tuned the meteorological histories of many others.

However, given scant observations from ships and weather stations, significant uncertainty of tropical cyclone tracks, intensity, and duration remains, particularly for those storms that stayed at sea.

[2] In Central America, however, the season's first hurricane wrought catastrophic rainfall resulting in an enormous loss of life, estimated somewhere between 1,000 and 3,000 people.

In July, a hurricane struck Texas, spawning tornadoes and generating storm surge, killing 19 people; damage was estimated around $4.5 million.

In late August and early September, another hurricane meandered offshore Texas while a weak tropical storm struck North Carolina, each causing minor damage.

A weak tropical storm affected the U.S. Gulf Coast in early October, and the season's only major hurricane meandered across the southwestern Atlantic at the end of November.

The cyclone had weakened to a tropical depression while over land, but it restrengthened once offshore again and became a Category 1 hurricane with winds of 80 mph (130 km/h) before making landfall in extreme northern Belize early on June 9.

The storm progressed across the Yucatán Peninsula in a weakened state but reacquired hurricane intensity as it made a second cyclonic loop over the Bay of Campeche.

Now moving north, the hurricane reached peak winds of 100 mph (160 km/h) and maintained that strength through landfall near Jeanerette, Louisiana, at 19:00 UTC on June 16.

[5][6] The cyclone proved to be catastrophic across El Salvador and western Honduras, where rainfall up to 25 in (640 mm) caused widespread flooding and one of the largest death tolls in the history of the Atlantic basin.

[9] Officials with the United States Red Cross estimated that 75–150 homes were demolished, 1,500 others were left uninhabitable, and between 3,000 and 7,000 more were damaged to some degree by the storm.

[12] Squalls from the system killed four people and injured many others in Mississippi, while heavy rainfall caused the Pearl River to exceed flood stage.

[13] Record rainfall during June in Tennessee, accumulating to 10 in (250 mm) in a matter of hours in Cedar Hill, caused about $250,000 in damage across the state.

The disturbance gradually shed this frontal boundary and acquired a well-defined center,[5] leading to the formation of a tropical depression around 00:00 UTC on July 12 to the east of the Florida–Georgia border.

[6] Based on extrapolation from nearby ship reports, the hurricane is analyzed to have reached peak winds of 90 mph (140 km/h) early on July 15.

[5] A tropical depression formed a short distance southeast of Charleston, South Carolina, around 06:00 UTC on July 22 and tracked southwest.

It continued inland across southern Texas and into northern Mexico and was last analyzed west of Piedras Negras, Coahuila, at 18:00 UTC on July 26.

[6] Minor impacts were recorded in Florida, where trees were toppled, pecans and pears were blown down, and corn crops were flattened.

[29] A weak tropical storm,[5] first documented east of Barbados at 18:00 UTC on August 20, moved west-northwest and entered the Caribbean Sea south of St. Lucia.

[5] It initially moved west-northwest off the coast of Louisiana but soon banked toward the south, passing within 25 mi (40 km) of Galveston, Texas, as it intensified into a Category 1 hurricane with winds of 80 mph (130 km/h).

On September 1, an extratropical low developed as the front began to dissipate,[5] and it quickly transitioned into a tropical storm by 06:00 UTC while south and west of Bermuda.

The system transitioned into an extratropical cyclone by 06:00 UTC on September 9 and curved northeast before dissipating over the Gulf of Saint Lawrence the following morning.

[6] The center of the hurricane narrowly missed the North Carolina Outer Banks, where winds of 72 mph (116 km) were recorded in Hatteras.

[39] Along the coastline, the United States Coast Guard attempted search and rescue of the SS Morro Castle which caught fire and killed 137 people on board, but these efforts were limited by low visibility at least partly attributed to the storm.

[45] On Lake Ontario, a Canadian National Railway car ferry was unexpectedly hit by a large wave, severely damaging the ship and injuring 52 people.

It alternated between a west-northwest and west motion for several days, narrowly missing the Leeward Islands and gradually strengthening to a peak intensity of 50 mph (80 km/h).

It progressed northwest through the Yucatán Channel and into the central Gulf of Mexico, where it attained tropical storm intensity early on October 3.

[6] The final and most intense storm of the 1934 season formed northeast of the Leeward Islands from the remnants of a trough or frontal boundary around 06:00 UTC on November 20.

[5] The Susan Maersk encountered the system to the west of island and suffered minor damage;[54] the Malacca too intercepted the storm and saw its decks flooded.

[6] It gradually lost intensity and made landfall on the northern coast of the Dominican Republic with winds of 45 mph (72 km/h) at 16:00 UTC on November 28.
