Tropical Storm Debby barrels toward Florida, with potential record-setting rains further north

MIAMI — Tropical Storm Debby strengthened rapidly Sunday and was expected to become a hurricane as it moved through the Gulf of Mexico toward Florida, bringing with it the threat of devastating floods to the southeast Atlantic coast later in the week.

The storm was likely to become a Category 1 hurricane before making landfall Monday in the Big Bend region of Florida, the National Hurricane Center in Miami said.

From there, the storm is expected to move eastward over northern Florida and then stall over the coastal regions of Georgia and South Carolina, drenching the region with the potential of record-setting rains totaling up to 30 inches beginning Tuesday.

"There's some really amazing rainfall totals being forecast and amazing in a bad way," Michael Brennan, director of the National Hurricane Center in Miami, said at a briefing Sunday.
