The first storm, Alex, developed offshore of the Southeastern United States on July 31, one of the latest dates on record to see the formation of the first system in an Atlantic hurricane season.

[17] August was an unusually active month, with eight named storms, including Alex, Bonnie, Charley, Danielle, Earl, Frances, Gaston, and Hermine.

This was the first time four tropical cyclones produced hurricane-force winds in one state during a single season since four hurricanes made landfall in Texas in 1886.

[24] Rough seas and a storm surge up to 6 ft (1.8 m) on the Outer Banks of North Carolina caused minor beach erosion and washed out portions of a highway in Cape Fear.

[33] In North Florida, scattered power outages were reported, and rainfall and storm surge flooded roads, especially in Taylor County.

Later that day, the storm emerged into the Atlantic, before making two more landfalls in Cape Romain and Myrtle Beach, South Carolina as a minimal hurricane.

After developing banding features and an increase in Dvorak intensity estimates, the depression was upgraded to Tropical Storm Earl at 18:00 UTC on August 14.

[45] Although Earl appeared well-organized, it unexpectedly degenerated into a tropical wave on August 16, after a reconnaissance aircraft reported no closed circulation.

[46] Damage on other islands was confined to a few impacted homes, moderate crop losses, and widespread power outages, especially in Saint Vincent and the Grenadines and Tobago.

On September 6, the storm emerged into the Gulf of Mexico near New Port Richey, before another landfall at the mouth of the Aucilla River with winds of 65 mph (105 km/h).

Between 13 and 17 percent of the non-native Australian pine on San Salvador Island experienced damage, primarily from snapping, though some browning from salt spray was noted.

[49] A frontal low-pressure area developed into Tropical Depression Seven at 12:00 UTC on August 27, while located about 130 mi (210 km) east-southeast of Charleston, South Carolina.

Initially, Gaston tracked slowly, moving southeastward and then westward, before a developing mid- to upper-level ridge re-curved the storm northwestward.

[59] In Chesterfield, Dinwiddie, Hanover, Henrico, and Prince George counties, 350 homes and 230 businesses were damaged or destroyed,[58] and many roads were closed due to high water.

Shortly thereafter, Ivan made a final landfall near Holly Beach, Louisiana with winds of 35 mph (56 km/h) and subsequently dissipated hours later.

Performing a slow curve over the eastern Atlantic, the wave became increasingly less-defined over subsequent days as a result of strong southwesterly wind shear.

Following the development of shower and thunderstorm activity near the center, the system acquired enough organization to be deemed a tropical depression at 12:00 UTC on September 7, while positioned about 725 mi (1,167 km) southwest of the southernmost Azores.

Hostile environmental conditions caused the depression to remain below tropical storm intensity and subsequently degenerate into a remnant low by 12:00 UTC on September 9 after the center decoupled from the remainder of the convective activity.

A deep-layer ridge slowly curved Jeanne to the west by the following day, around the time it weakened to a Category 1 hurricane due to upwelled waters.

[55] In Dominican Republic, major flooding was reported, with rivers overflowing, bridges collapsing, roads cut off, damage to agriculture, and mudslides.

The wave gradually became better organized, and the NHC designated it Tropical Depression Twelve on September 16, while the system was located about 670 miles (1,080 km) west-southwest of the Cape Verde islands.

[76] Due to healthy outflow around an upper-level anticyclone and warm sea surface temperatures of the year, rapid deepening began on the evening of September 17,[77] with the storm developing a small eye.

Despite unfavorable conditions due to outflow from nearby Hurricane Karl, the depression strengthened into Tropical Storm Lisa on September 20.

After nearly reaching hurricane status, Lisa began executing a small cyclonic loop due to a Fujiwhara interaction with a tropical wave.

After briefly weakening, Matthew attained its peak intensity late on October 9, with maximum sustained winds of 45 mph (72 km/h) and a minimum barometric pressure of 997 mbar (29.4 inHg).

[86] A combination of storm surge and heavy rainfall inundated numerous roads in Lafourche, Orleans, St. Bernard, St. John the Baptist, St. Tammany, and Terrebonne parishes.

[87] The interaction between an upper-level trough and a decaying cold front led to the development of a low-pressure area on October 8 to the southwest of Bermuda.

Early on October 10, the low developed a curved band of convection northwest of the center, and it organized into Subtropical Storm Nicole by 06:00 UTC.

[87] Similarly, 11,300 people were left without electricity in Prince Edward Island and New Brunswick alone after winds uprooted trees and toppled power lines.

After losing frontal characteristics, the system transitioned into Subtropical Storm Otto at 12:00 UTC on November 29, while located about 1,150 mi (1,850 km) east-southeast of Bermuda.
