The tropical storm warning has been extended northward along the west coast of the Florida peninsula from Bonita Beach to Boca Grande, and the tropical storm watch now extends from Aripeka to the mouth of the Suwannee River.
Potential Tropical Cyclone Four is expected to develop into a tropical storm Saturday as it moves across the Straights of Florida, where it is expected to intensify into Tropical Storm Debby by Saturday Night.
Potential Tropical Cyclone Four is now located over eastern Cuba, about 315 miles southeast of Key West, according to the latest advisory.

Florida Gov. Ron DeSantis Thursday declared a state of emergencyfor 54 of Florida's 67 counties ahead of the storm, includingEscambia and Santa Rosa counties.

Maximum sustained winds are still near 30 mph. If sustained winds reach 39 mph, it would become Tropical Storm Debby, thefourth named stormof the 2024 Atlantic hurricane season.

A tropical storm watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.
Potential impact from tropical cyclone
WINDS: Tropical storm conditions are expected in the warning area late Saturday and Saturday night. Tropical storm conditions are possible in the watch area in the Florida Keys and the southern Florida peninsula by Saturday or Saturday night. Tropical storm conditions are possible in the watch area along the Florida west coast Saturday night or 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:
- Aripeka to Card Sound Bridge, 1-3 feet
- Tampa Bay...1-3 feet
- Charlotte Harbor...1-3 feet
RAINFALL: Potential Tropical Cyclone Four is expected to produce rainfall totals of 4 to 8 inches, with maximum rainfall totals up to 12 inches, across portions of Florida and near the Southeast U.S. coast this weekend through Wednesday morning. This rainfall could result in areas of flash and urban flooding, with isolated river flooding possible.
What impact can Florida expectfrom Invest 97L
"Downpours and gusty thunderstorms will spread westward across Cuba and the western islands of the Bahamas on Friday before spreading over the Florida Keys and the southern part of the Florida Peninsula on Saturday.
"Along with the potential for urban flooding will be the risk of waterspouts and hazards for beach and boating interests, at the very least," AccuWeather said.
"As the system approaches and begins to strengthen, rip currents will increase in strength and number along the Florida coastline this weekend.
"Should the storm stay east of Florida, the rough surf conditions will spread northward along the Atlantic coast. If the center migrates farther to the northwest, then surf conditions will build along the Gulf Coast."
