Tropical Storm Debby is moving slowly to the Florida coast on Sunday, June 24.
This brings strong winds and waves that forced the closure of about a quarter of offshore oil and gas production in the Gulf of Mexico.
Several Alabama beaches were closed due to rough surf.
According to an emergency management official, earlier on Sunday, it caused tornadoes that killed a woman, severely injured a child and wrecked homes in central Florida in rural Highlands County.
The National Hurricane Center maintained a storm warning for the Mississippi-Alabama border, extended warnings for Florida’s northwest coast to Englewood, and discontinued warnings for the Louisiana coast.
Residents were warned to expect storm conditions within 36 hours.
