Tropical Storm Arlene An area of thunderstorms in the eastern Pacific Ocean crossed Central America into the western Caribbean, developing a low-level circulation on May 5 offshore
Honduras. Convection organized enough that a tropical depression formed on May 6 near the
Cayman Islands. It was a rare example of an Atlantic depression forming from a disturbance that originated in the eastern Pacific. Spiral rainbands developed around the center, and the depression intensified into Tropical Storm Arlene on May 7 while moving generally northeastward, Arlene struck eastern Cuba early on May 8 with winds of 50 mph (85 km/h). Strong wind shear and Arlene's passage over land weakened the storm to a tropical depression and caused its circulation to become ill-defined. After an area of convection reformed, Arlene re-intensified after exiting Cuba, There were no reports of damage or casualties from Cuba or the Bahamas, and therefore storm affects were judged to have been minimal. later, peak winds in the Bahamas reached around 35 mph (55 km/h). 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.
Tropical Depression Two A tropical depression formed in the Bay of Campeche on June 3. Classified as Tropical Depression Two, the system moved north-northwest, lured by a closed upper-cyclone over the southern
Great Plains. with at least 23 homes suffering water damage. Water also entered city hall. Some roads had roughly of standing water, stranding some motorists for hours. In
Galveston, a tornado damaged forty homes and apartments, with severe damage to three homes and two apartment units. One business suffered major roof damage, while several cars were damaged at an auto dealership. Overall, the depression killed three people, two due to flooding and one from an associated tornado. At least $4 million in damage was caused by this depression. Locally heavy rains in western
Pennsylvania caused some basement and street flooding. No significant damage was reported,
Tropical Depression Four In association with a tropical wave, a tropical disturbance formed over the Caribbean south of Cuba. As a disturbance crossed the Yucatán Peninsula, it interacted with an upper-level low-pressure area centered to the west. After emerging into the south-central Gulf of Mexico, the disturbance organized into a tropical depression early on July 25. In the Caribbean, Dennis dropped heavy precipitation on some islands, including
Martinique,
Saint Lucia, the
Virgin Islands, and the Greater Antilles. Flooding in Jamaica left at least 50 people homeless. In Florida, heavy rain fell in many areas to the east of the storm's path. Much of southeast Florida received at least of precipitation, while over of rain fell in
Homestead. However, the worst damage was incurred to crops, which experienced a loss of over $17.26 million. One death and nearly $18.5 million in damage occurred in Florida. Farther north, Dennis also caused flooding in the Carolinas, inundating many streets and causing crop damage in both states. Twenty families in
Columbus County, North Carolina, evacuated after the
Waccamaw River overran its banks. Overall, Dennis left caused three deaths and about $28.5 million in damage. The subtropical depression intensified into a subtropical storm and then transitioned into Tropical Storm Emily on the following day. Emily moved northeast, passing close to Bermuda on September 2. A large high-pressure system caused the storm to executive a cyclone loop on September 3 and September 4, before resuming a northeast motion. After passing near or over several
Leeward Islands in a northwestward trajectory, the depression intensified into Tropical Storm Floyd late on September 4 and then reached hurricane status about 24 hours later. Because Emily eroded the western side of a high-pressure ridge, Floyd turned northward on September 6. Rains and winds up to 60 mph (95 km/h) impacted the island, but damage was minor. Gale warnings were issued for the Turks and Caicos Islands and later the southeastern Bahamas, and light rainfall occurred in the region, reaching on the island of
San Salvador. Winds were light in Bermuda. The westerlies caused the cyclone to gradually turn eastward. and was initially expected to intensify into a tropical storm. Although it failed to further intensify, Tropical Depression Thirteen brought squalls to Bermuda with winds gusts of tropical storm-force as it passed west of the island later that day. Moving northward, the system merged with a developing
extratropical cyclone south of Nova Scotia on September 24. although deep convection remained unconcentrated from the center for three more days. The depression intensified into Tropical Storm Irene on September 23. The storm tracked northwest under the influence of two high pressure areas to the northeast and northwest and an upper-level trough, becoming a hurricane on September 25. Irene then began to curve eastward as it gradually strengthened. Accelerating northeastward due to the upper-level trough, Irene then gradually weakened, falling below hurricane strength on October 1. while light precipitation fell on Puerto Rico and the
United States Virgin Islands, peaking at near
Peñuelas. The depression then recurved to the south and east of Bermuda late on October 4.
Tropical Storm Jose On October 20, a mid-latitude low-pressure area was located well east of Atlantic Canada. The low moved southward for eight days. Convection increased around the center of circulation on October 29, Moving generally northeastward,
Hurricane Katrina A tropical depression formed on November 3 in the western
Caribbean Sea about south of the
Cayman Islands. The depression moved north, reaching tropical storm strength as it moved through the Cayman Islands. Katrina continued to strengthen, reaching hurricane strength and peaking with maximum sustained winds of 85 mph (140 km/h) and a minimum atmospheric pressure of on November 5. On the following day, the storm struck
Camagüey Province in
Cuba and quickly weakened to a tropical storm. After emerging over water near
Ragged Island in the Bahamas, the storm accelerated northeast through the island chain. Katrina's circulation fell apart, and the storm merged with a front on November 8 while centered about south of Bermuda. Katrina also damagede approximately 80% of sugar cane crops. Two deaths also occurred in Cuba.
Subtropical Storm Three A low-pressure area developed along a cold front over the warm waters of the
Gulf Stream. After moving northeastward, it turned to the northwest, threatening the northeastern United States as an intensifying subtropical storm that was gradually developing tropical characteristics. A high pressure system turned it to the northeast, Some sections of
Maryland beaches lost up to of sand, threatening coastal homes. In
Delaware,
South Bethany lost thousands of tons of sand, while waves swept away about half of the dune at the
Indian River Inlet, the latter costing an estimated $95,000 to replace.
Other systems Four additional tropical depressions formed during the season which were operationally thought to have not developed and thus went unnumbered. The first such system developed northeast of the Lesser Antilles on April 6. Moving slowly southwestward, the depression dissipated over the
Anegada Passage about 24 hours later. A small craft advisory and special marine warning were issued by the National Weather Service office in
San Juan, Puerto Rico. On April 19, another tropical depression formed over the southwestward Caribbean. The depression moved northeastward through the following day, before doubling-back to the southwest and dissipating by April 21. Another previously unnumbered tropical depression formed over the Bay of Campeche on June 17. It made landfall in Mexico south of Tampico before dissipating about two days later. A fourth unnumbered tropical depression developed near
Andros on July 2. It made landfall in southeast Florida and later in South Carolina before dissipating on July 4. The depression dropped up of rainfall in
Broward County, Florida, causing localized flooding. A waterspout-turned-tornado at
Port Everglades overturned a shed and downed some power lines. 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. ==Storm names==
