Meteorological history

. By the following day, a large and disjointed area of low pressure had formed in the vicinity of the wave; however, contrary to what would be expected of a tropical cyclone, the associated thunderstorm activity was not organized in curved banding features, indicating the storm was still in its early developmental stages.

 identified a low-level circulation center accompanying the system, but it remained weak. A still-broad disturbance continuing westward at around 17 miles per hour (27.4 km/h), its convection began to take on a curved pattern, and on August 19 became situated around a distinct center of low pressure. In light of the improvements in the storm's structure, it was recognized as a tropical depression that same day while located roughly 1000 miles (1,609.3 km) west of the Windward Islands

 to hinder the depression's progress and developing anticyclonic outflow aloft, the cyclone attained tropical storm status at 0600 UTC on August 20 and received the name Debby.

Tropical Storm Debby quickly strengthened to a Category 1 hurricane
