Florida is bracing for a “major disaster” this weekend as a powerful storm system could develop into Tropical Storm Debby, potentially bringing up to a foot of rain that could cause flooding and power outages and bring gusty winds.

Gov. Ron DeSantis declared a state of emergency Thursday in anticipation of the “significant threat of heavy rainfall over most of the State of Florida.”

As of Friday evening, a tropical wave originally named “Invest 97L,” but referred to as Potential Tropical Cyclone Four by the National Hurricane Center, is moving northwest in the Atlantic near Cuba, according to forecasters.

According to the 5 p.m. advisory, the storm was around 315 miles southwest of Key West, Fla., with maximum sustained winds of 30 mph.

If the tropical wave — a disturbance of unorganized showers and thunderstorms — reaches sustained wind speeds of 39 mph, it would form into Tropical Storm Debby, making it the fourth named storm for this year’s Atlantic hurricane season.

The tropical wave is expected to move over Cuba and barrel to the Florida Straits, southeast of Florida’s mainland, on Saturday morning, meteorologists predict.

The storm is then expected to head to Florida’s west coast, stretching to the Big Bend in the northern part of the state, on Sunday night. By Monday night, meteorologists expect the storm to move through Florida and into Georgia’s southeastern tip.

The NHC warned of heavy rainfall across portions of Florida and the Southeast into Wednesday morning, warning that the storm system should be monitored from Georgia to North Carolina.

As of Friday morning, the NHC issued tropical storm watches and warnings for the Florida Keys — a chain of islands off the southern coast of Florida — and for portions of the west coast of the Florida Peninsula.

A tropical storm warning — which means storm conditions are expected somewhere within the area within 36 hours — is in effect, per the NHC, for:

  • The southwest coast of the Florida Peninsula from East Cape Sable to Boca Grande

A tropical storm watch — meaning tropical storm conditions are possible within the area, usually within 48 hours — is in effect, according to the NHC’s Friday morning advisory, for:

  • The Florida Keys south of the Card Sound Bridge including the Dry Tortugas

  • The southern coast of the Florida Peninsula east of East Cape Sable to the Card Sound Bridge

  • The west coast of the Florida Peninsula north of Boca Grande to the Suwannee River

DeSantis has declared a state of emergency for 54 of Florida’s 67 counties and warned of at least 12 inches of rainfall stretching over the next seven days, unleashing flash, river and coastal flooding.

“These conditions could damage the operational capability of critical infrastructure to include major interstates and roadways, bridges, airports, schools, hospitals, power grids, and other critical infrastructure,” the executive order read.

The declaration allows emergency response agencies to implement their emergency plans, including carrying out rescue or evacuation operations.

“I encourage all residents to prepare for the storm and follow all guidance issued by @FLSERT and local emergency management officials,” DeSantis posted on X on Thursday.
