Debby is drenching the state with rain and has caused flooding.
The tropical storm warning area shifted farther south Monday to encompass much of Florida's Gulf coast. Debby has weakened slightly and now has top sustained winds of 45 mph (72 kph). The storm is about 75 miles (121 kilometers) south of Apalachicola and is moving northeast at 3 mph (5 kph).
An isolated tornado from the storm killed one person and authorities are continuing to look for another person who disappeared in the surf in Alabama.
Its slow progress means the most pressing threat from the storm is flooding, not wind.

In Alabama, crews plan to continue searching for a South Carolina man who disappeared in rough surf.
The storm has prompted the closing of a bridge to Florida's St. George Island, a popular vacation spot.
Residents in several counties near the crook of Florida's elbow have been urged to leave low-lying neighborhoods because of the threat of flooding.
Authorities in the Tampa Bay area are asking people to stay away from flooded streets. Some streets were under water Monday, while others were blocked with debris.
