Tropical Depression Eight was the most devastating storm of the season, causing five fatalities and $56.2 million in damage due to flooding over southeast Texas in August.

During the same month, Hurricane Dennis produced heavy rainfall across Florida's Miami metropolitan area and in parts of southeastern North Carolina, killing three people and leaving about $28.5 million in damage.

[5] Tropical Depression Two moved out of the Gulf of Mexico into eastern Texas on June 5, producing localized rainfall amounts of 12 in (300 mm) and numerous tornadoes over Louisiana before recurving across the Southeast United States.

[2] Tropical Storm Bret formed as a subtropical low in the open Atlantic Ocean north of Bermuda on June 29, and made landfall in the Delmarva Peninsula.

[22] The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 100,[23] which is classified as "near normal" by NOAA and is slightly higher than the 1951-2000 average of 93.2.

[23] An area of thunderstorms originated in the eastern Pacific Ocean in early May, which crossed Central America into the western Caribbean, developing a low-level circulation on May 5 off the coast of Honduras.

Spiral rainbands developed around the center, and the depression intensified into Tropical Storm Arlene on May 7 while moving generally northeastward, steered by a ridge to its north.

After an area of thunderstorms reformed, Arlene re-intensified after exiting Cuba, reaching winds of 60 mph (95 km/h) over the southeastern Bahamas, based on observations from the Hurricane Hunters.

[24][25][26][27][28] As Arlene was approaching its first landfall, the National Hurricane Center noted the potential for heavy rainfall in Jamaica, Cuba, and the Bahamas; small boats in those regions were advised to remain at harbor.

[31] Arlene was the only May tropical storm on record to affect the Cuban province of Camagüey, although its passage was mostly noticed in its disruption of sugar cane production.

Classified as Tropical Depression Two, the system moved north-northwest, lured by a closed upper-cyclone over the southern Great Plains.

[6] The depression, in conjunction with an upper-level low, dropped heavy rainfall in the Greater Houston area, with a peak total of 15 in (380 mm) at Lake Anahuac.

[6] A low-pressure area initially associated with a frontal system developed into a subtropical storm on June 29 while roughly 575 mi (925 km) east of Cape Hatteras, North Carolina.

Bret attained its peak intensity six hours later with maximum sustained winds of 70 mph (110 km/h) and a minimum atmospheric pressure of 996 mbar (29.4 inHg).

However, Bret rapidly weakened as it approached the Mid-Atlantic and deteriorated to a minimal tropical storm by the time it made landfall on the Delmarva Peninsula early on July 1.

An area of disturbed weather along the tail-end of the front subsequently began to develop cyclonic banding, resulting in the formation of a subtropical depression late on August 2 about 310 mi (500 km) northwest of Bermuda.

After crossing the Windward Islands on August 12, Dennis entered the Caribbean but degenerated into a tropical wave early the following day.

Dennis reintensified into a tropical storm around 00:00 UTC on August 16, just prior to landfall near Playa Girón, Matanzas Province.

Dennis continued to intensify and made landfall near Emerald Isle, North Carolina, but moved east-northeastward and soon tracked offshore.

Moving northwestward, the cyclone failed to intensify into a tropical storm before making landfall in the Mexican state of Tamaulipas to the north of Tampico on August 28, with winds of 35 mph (56 km/h).

This resulted in heavy rainfall across southeastern Texas, with a peak total of 21 in (530 mm) in Pine Springs in Fayette County,[11] with much of that falling in only about six hours.

[11] Throughout Lavaca County, more than 286 homes were damaged or destroyed, 17 bridges and several roads were washed out, and hundreds of head of cattle were drowned.

Early on September 7, satellite imagery indicated that Tropical Depression Eleven formed about 400 mi (645 km) east of the Leeward Islands.

The newly upgraded storm passed between Dominica and Guadeloupe and continued to intensify, making landfall on southeastern Puerto Rico with winds of 60 mph (97 km/h) late on September 8.

The hurricane turned northeastward and weakened over cooler waters, passing about 100 mi (160 km) north of Bermuda on September 12 as a tropical storm.

[20] A tropical depression formed on November 3 in the western Caribbean Sea about 150 mi (240 km) south of the Cayman Islands.

[56] A frontal low over the warm waters of the Gulf Stream organized into a subtropical storm on November 12 while 400 miles (640 km) east of Jacksonville, Florida.

After moving northeastward, it turned to the northwest, threatening the northeastern United States as an intensifying subtropical storm that was gradually developing tropical characteristics.

[2] A small craft advisory and special marine warning were issued by the National Weather Service office in San Juan, Puerto Rico.

[58] Heavy precipitation also fell in South Carolina, especially in Clarendon and Sumter counties, inundating crops and flooding some cars, homes, a school, and stores in the Mayesville area.
