, located to the west of an upper-level low, developed convection to the east of the Bahamas on July 26. A tropical wave entered the area two days later, resulting in an increase of convective organization and area. Although conditions were not favorable for tropical cyclone formation, it sped to the northwest and steadily organized, developing a surface area of low pressure on the 30th. On July 31, the system continued to organize, and developed into Tropical Depression One while located 200 miles (320 km) to the east of Jacksonville, Florida

.

As the depression drifted erratically, the system remained weak due to its large circulation and lack of deep convection near the center. The center relocated to the south, closer to the center. An approaching upper-level trough lessened the shear over the system, allowing the depression to intensify into Tropical Storm Alex on August 1. The trough also caused Alex to increase its forward motion to the northeast. Deep convection continued to build over the center due to low shear and warm waters from the Gulf Stream

Alex turned to the east-northeast after passing the Outer Banks in response to becoming embedded within the west-southwesterly flow. The hurricane briefly weakened to a Category 1, but restrengthened due to warm waters of the Gulf Stream

Preparations

Initially, forecasters believed Alex would remain weak, and on the first advisory the storm was predicted to make landfall as a minimal tropical storm. However, when strengthening became evident, the National Hurricane Center issued a hurricane warning

 nineteen years earlier. Elsewhere on the Outer Banks, waters rose 2–4 feet (0.6–1.2 m) above normal. Rainfall directly along the coast amounted to over 5 inches (127 mm), while Ocracoke experienced 7.55 inches (192 mm). Maximum sustained winds peaked at 88 mph (124 km/h), and gusts peaked at 115 mph (169 km/h) in Morehead City. Beach erosion was minor along much of North Carolina's coastline, with the exception of Ocracoke Island where erosion was significant.

Cape Fear experienced minor beach erosion. The erosion, combined with high waves, washed out a portion of a roadway. The heavy rainfall in the Outer Banks disabled over 200 cars and flooded nearly 500. Strong wind gusts left around 10,000 buildings without power. Many places were not restored for two to three days after the storm. Wind and storm surge damaged over 100 houses and buildings. Damage amounted to about $7.5 million (2004 USD).

Aftermath and records

On Ocracoke Island, officials ordered for the evacuation of the thousands of tourists who stayed, believing that keeping tourists on the island would hinder cleanup efforts. The tourists were evacuated in school buses to Hatteras Island, where they could rent a car if needed. Tourists were also evacuated by ferry to Swan Quarter, in Hyde County, where they boarded school buses and were taken to nearby Washington NC to rent available cars or find accommodations. The island was re-opened to visitors on August 6, three days after the storm passed through. Evacuation was ordered again on Friday of the following week when another storm threatened to hit the Outer Banks, but did not do so. Dare County
