[18] On July 2, WSI held firm to their April forecast;[19] the organization was forced to slightly increase the number of named storms and hurricanes later that month.

[24] Despite a La Niña dissipating early in the summer months, atmospheric conditions remained favorable for tropical cyclogenesis, including abnormally low wind shear between 10°N and 20°N.

[22] The season was devastating for Haiti, where four consecutive tropical cyclones – Fay, Gustav, Hanna, and Ike – killed at least 793 people and caused roughly $1 billion in damage.

[39][40] Bertha was an early season Cape Verde-type hurricane that became the longest-lived July North Atlantic tropical cyclone on record, though it caused few deaths and only minor damage.

In conjunction with Alma, Tropical Storm Arthur dropped over 12 in (300 mm) of rainfall across portions of Belize, destroying roads, washing out bridges, and damaging 714 homes.

Meanwhile, Bertha produced large waves and rip currents along the U.S. East Coast, resulting in 3 deaths offshore New Jersey and 57 water rescues in Atlantic City alone.

After passing close to the Outer Banks of North Carolina, the storm continued northeast and reached peak winds of 65 mph (105 km/h) early on July 21, when an eye feature was evident on microwave imagery.

[56] Generally lesser rainfall totals occurred across the Southeastern United States,[50] though record daily accumulations around 3.43 in (87 mm) resulted in minor flooding in Wilmington, North Carolina.

However, the system did not develop a well-defined circulation until around 12:00 UTC on July 20, at which time it was designated as Tropical Storm Dolly about 310 mi (500 km) east of Chetumal, Quintana Roo.

Dry air and cooler waters eroded the storm's eyewall after peak intensity, but Dolly still harbored winds of 85 mph (137 km/h) at its landfall on South Padre Island, Texas, at 18:20 UTC.

[63] The remnants of the storm heavy impacted Ciudad Juárez, Chihuahua, where five homes and a historic church were collapsed and about 2,840 acres (1,150 hectares) of corn and barley were ruined.

[64] Farther north in New Mexico, an estimated 350–500 structures were damaged, roads and bridges were washed out, and one man was swept away by the swollen Rio Ruidoso river.

[67] Wind gusts in Louisiana peaked at 62 mph (100 km/h), ripping the roofs of mobile homes, downing numerous trees, and toppling power lines across Cameron, Calcasieu, and Vermilion parishes.

The cyclone weakened to a tropical depression in the Florida Panhandle on August 24 and moved northwest into Mississippi before making an abrupt turn to the northeast the following day.

[45] Upon striking the United States, Gustav produced strong winds that damaged the roofs and windows of many structures,[87] as well as a large storm surge along the coastline of Louisiana which overtopped levees and floodwalls in New Orleans.

While the exact death toll is indiscernible due to the quick succession of tropical cyclones,[37] Hanna is believed to have killed at least 529 people in Haiti, most in the commune of Gonaïves, as well as 1 person in the Dominican Republic.

A strong subtropical ridge to the depression's north directed it on a west-northwest path for several days, while environmental conditions allowed for quick intensification.

Land interaction prompted structural changes to the storm's core, and Ike only slowly rebounded to an intensity of 110 mph (180 km/h) before its landfall on the northern end of Galveston Island, Texas, early on September 13.

[45][89] While progressing across the Gulf of Mexico, Ike's slow movement and unusually large wind field led to a huge storm surge, upwards of 15–20 ft (4.6–6.1 m), that devastated the Texas coastline.

The westward-moving feature crossed the Windward Islands on September 19 and began to interact with a strong upper-level trough, leading to an increase in convection and a more evident circulation center.

Gradual intensification occurred as the cyclone passed well west of Bermuda; it attained hurricane strength around 12:00 UTC on September 27 and reached peak winds of 85 mph (137 km/h) a day later.

[94] The precursor disturbance to Kyle produced up to 30.47 in (774 mm) of rainfall in Puerto Rico,[50] resulting in numerous flash floods and mudslides that killed six people.

[98] Kyle produced hurricane-force winds along the southwestern coastline of Nova Scotia that uprooted trees while damaging boats, docks, wharves, and a building under construction.

Favorable anticyclonic flow aloft aided in continued development of the tightly coiled storm, and Marco attained peak winds of 65 mph (105 km/h) early on October 7, an intensity it maintained through landfall east of Misantla around 12:00 UTC that day.

The effects of strong wind shear mitigated further organization, weakening the storm back to tropical depression intensity by 12:00 UTC on October 13 and causing it to degenerate to a remnant low a day later.

A broad upper-level trough to the cyclone's northwest caused it to conduct a counter-clockwise turn and accelerate northeast while also aiding in the onset of an extended period of rapid intensification.

Omar attained hurricane strength around 00:00 UTC on October 15 before ultimately reaching peak winds of 130 mph (210 km/h) a little over a day later shortly after passing near Saint Croix.

In what was described as the region's worst flooding disaster since Hurricane Mitch, crops suffered catastrophic losses, tens of thousands of homes were destroyed, and dozens of people were killed.

It moved north amid a favorable environment, becoming Tropical Storm Paloma twelve hours after formation and attaining hurricane intensity by 00:00 UTC on November 7.

An increase in wind shear soon began to take a toll on the cyclone, weakening Paloma to Category 2 strength as it made landfall near Santa Cruz del Sur, Cuba, and further to a tropical storm around 06:00 UTC on November 9.
