Forecasters say Tropical Depression Debby still poses a threat as it slowly makes its way across Florida towards the Atlantic Ocean.

Debby was last spotted by the U.S. National Hurricane Center about 175 kilometers west of the popular tourist city of Daytona Beach, carrying maximum sustained winds of 55 kilometers per hour. The storm was downgraded to a tropical depression after making landfall Tuesday on the Florida Gulf Coast.

Forecasters have canceled all tropical storm warnings, but say that Debby can still dump anywhere between 5 and 65 centimeters of rainfall across northern Florida, and also cause coastal flooding and possible tornadoes.

The storm already has dumped some 25 centimeters of rain along the Florida-Georgia border, with some towns receiving more than 66 centimeters of rain in three days. One woman was killed in a tornado spun off from Debby on Sunday.

The White House says President Barack Obama has called Florida Governor Rick Scott and promised the federal government will do everything to ensure the state will have “no unmet needs” as it deals with the storm's aftermath.
