Tropical Depression Four's path shifted west slightly Friday night, slowing its timeline and prompting a hurricane watch along a portion of Florida's Gulf Coast.
As of 2 p.m., the storm is about 115 miles southwest of Key West, according to the Gov. Ron DeSantis' office late afternoon update. On the forecast track, the center of the depression will move across western Cuba and over the eastern Gulf of Mexico later Saturday and Sunday, reaching the Florida Gulf coast late Sunday or Monday. It was moving at 15 mph with winds about 35 mph and picking up.
The majority of Florida is still under a state of emergency after DeSantis made the declaration on Thursday.
Previous paths for Tropical Depression Four put a potential landfall somewhere along the coast of Florida's Big Bend on Sunday, but the storm's path has since shifted. Now, the eye of what is likely to become Tropical Storm Debby later today will make landfall sometime between early Monday morning and Monday afternoon.
To become a tropical storm, sustained winds must reach 39 mph. The storm has maintained sustained winds of 30 mph since Friday.

The governor declared astate of emergencyfor the majority of Florida — including Duval, Baker, Clay, Flagler, Nassau, Putnam and St. Johns counties — allowing state officials "to make critical resources available to communities ahead of any potential areas that the storm may impact," the Governor's Office said.
How is Jacksonville preparing for Tropical Storm Debby?
The Duval County Emergency Operations Center has partially activated to ensure continued coordination of storm preparation, response and stakeholders, the city said Saturday afternoon."This allows us to bring together key agencies and personnel to streamline communication, ensure rapid deployment of resources and address any needs quickly."
First responder response teams are on standby, and the Public Works Department continues to clear drainage systems in low-lying areas. The Fire and Rescue Department, Sheriff’s Office, JEA and Public Works also stand ready to mobilize and respond as needed as the tropical system approaches, the city said.
Currently there are not any planned evacuation orders, shelter openings or schedule changes for city of Jacksonville offices, the Jacksonville Transportation Authority or Duval County Public Schools.They will continue to monitor the storm forecast and provide updates to the public.

Tropical Depression Four path
When will Tropical Depression Four strengthen into Tropical Storm Debby?
The NHC expects that Tropical Depression Four will become Tropical Storm Debby later today, and continue strengthening in the eastern Gulf of Mexico through the weekend.
How much the storm strengthens will depend on how long it spends over the Gulf of Mexico's warm waters.
Could Tropical Storm Debby become a hurricane?
While it's not currently expected to strengthen into a hurricane, the chance isn't completely off the table. If Tropical Depression Four stalls offshore, it could rapidly intensify and become a strong tropical storm or a hurricane.
"It is possible if the feature bumps along the Florida Peninsula's west coast and interacts with the land, strengthening may be limited," AccuWeather Lead Hurricane Expert Alex DaSilva said. "A quick landfall over the southwest part of the Florida Peninsula would tend to really limit the time spent over the Gulf and limit the strengthening process.
The storm's new path leads it down DaSilva's second scenario.
"However, if the feature stays more offshore until Sunday evening or night and moves in along the upper Gulf coast of Florida, it may have time to quickly ramp up and become a strong tropical storm or hurricane before pushing inland over northern Florida," DaSilva warned.

Hurricane, tropical storm watches and warnings issued for Florida
A hurricane watch is in effect for:
- Aucilla River to Yankeetown
A hurricane watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous.
A tropical storm warning is in effect for:
- The Dry Tortugas
- West coast of the Florida peninsula from south of Yankeetown to East Cape Sable
A tropical storm warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.
A tropical storm watch is in effect for:
- The Florida Keys south of the Channel 5 Bridge
- West of the Aucilla River to the Ochlockonee River
A tropical storm watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.
A storm surge watch is in effect for:
- Bonita Beach northward to the Aucilla River, including Tampa Bay and Charlotte Harbor
A storm surge watch means there is a possibility of life-threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours.
Potential impacts from Potential Tropical Cyclone Four
WINDS: Hurricane conditions are possible in the hurricane watch area by Sunday night, with tropical storm conditions possible earlier on Sunday. Tropical storm conditions are expected to spread northward over the warning areas beginning later today and continuing through Sunday. Tropical storm conditions are possible in the watch area in the Florida Keys later today or tonight and in the Florida Panhandle by late Sunday.
STORM SURGE: The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:
- Chassahowitzka, FL to Aucilla River, FL...3-5 feet
- Bonita Beach, FL to Chassahowitzka, FL...2-4 feet
- Tampa Bay...2-4 feet
- Charlotte Harbor...2-4 feet
RAINFALL: Tropical Depression Four is expected to produce rainfall totals of 5 to 10 inches, with maximum rainfall totals up to 15 inches, across portions of Florida and along the Southeast U.S. coast this weekend through Thursday morning. This rainfall may result in areas of locally considerable flash and urban flooding, with isolated river flooding possible.
For Cuba, rainfall amounts of 1 to 2 inches, with localized higher amounts, will be possible through today. This may result in isolated to scattered areas of flooding.
TORNADOES: A tornado or two is possible across the Florida Keys and the western Florida Peninsula tonight through Sunday morning.
SURF: Swells generated by the depression are expected to affect much of the Gulf coast of Florida tonight through Monday and along the Southeast U.S. coast early next week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
Key messages on what Florida can expect from tropical cyclone
- Heavy rainfall may result in locally considerable flash and urban flooding across portions of Florida and the coastal areas of the Southeast U.S. this weekend through Wednesday. Isolated river flooding will also be possible.
- A Hurricane Watch has been issued for portions of west-central Florida and the Big Bend region, where hurricane conditions are possible late Sunday. Tropical storm conditions are expected farther south along Florida's west coast, including the Tampa Bay area, and across the Dry Tortugas where Tropical Storm Warnings are in effect.
- There is a possibility of life-threatening inundation from storm surge along portions of the west coast of Florida from Bonita Beach to Aucilla River, including Tampa Bay and Charlotte Harbor, where a Storm Surge Watch is in effect.
- Impacts from storm surge, strong winds, and heavy rains are possible elsewhere in Florida and along the southeast coast of the United States from Georgia to North Carolina through the middle of next week, and interests in those areas should continue to monitor the progress of this system. Additional watches and warnings will likely be required later today.
