The Latest: Debby knocks out power to hundreds of thousands in Florida, Georgia

Hurricane Debby made landfall in one of the least populated areas of Florida, but forecasters warned heavy rain could spawn catastrophic flooding in Florida, South Carolina and Georgia. About 300,000 customers were without power in Florida and Georgia on Monday, according to PowerOutage.com.

The National Hurricane Center in Miami said Debby has maximum sustained winds of 75 mph.

Big worry is storm surge from Debby

Forecasters said storm surge was expected to be the biggest threat for Florida, with 6 to 10 feet (1.8 to 3 meters) of inundation above ground level predicted in part of the zone near the Big Bend.

“That part of the coast is a very vulnerable spot,” John Cangialosi, a hurricane specialist with the National Hurricane Center, said Monday. Some areas, including Sarasota and Manatee counties, have already received 10 to 12 inches (25 to 30 centimeters) of rain.

In Georgia, the National Weather Service is predicting major flooding on some rivers: the Canoochee River near Claxton, the Ohoopee River near Reidsville and the Ogeechee River near Eden. All those rivers were below flood stage Monday but could see their water levels more than double by later in the week.

Hundreds of thousands without power

About 300,000 customers were without power in Florida and Georgia on Monday, according to PowerOutage.com.

Florida Gov. Ron DeSantis said some 17,000 linemen are working to restore electricity. He warned residents in affected areas to sit tight until conditions are safe.

“When the water rises, when you have streets that can be flooded, that’s hazardous,” DeSantis said. “Don’t try to drive through this. We don’t want to see traffic fatalities adding up. Don’t tempt fate, don’t try to go through these flooded streets.”
