PALM BAY, Fla., Oct. 25, 2026 —
Coastal flood warnings stretch along almost all of Florida's Atlantic coast tonight, from the Georgia line to the Florida Keys. The National Weather Service says seasonal king tides combined with persistent gusty northeast winds are pushing saltwater into streets, yards and low-lying neighborhoods, and the worst of it is expected Monday and Tuesday.
Where the warnings are
- Northeast Florida beaches (coastal Nassau, Duval, Flagler and St. Johns): significant coastal flooding around high tide until 5 a.m. Wednesday, with 8- to 10-foot breaking waves, NWS Jacksonville says.
- St. Johns River basin (inland Flagler, eastern Clay, eastern Putnam, south-central Duval, western St. Johns): moderate flooding around high tide until 5 a.m. Wednesday.
- Space Coast and Treasure Coast (coastal Volusia, Brevard, Indian River, St. Lucie and Martin): significant coastal flooding and 7- to 12-foot breaking waves until 2 a.m. Wednesday, NWS Melbourne says. A wind advisory runs until 8 a.m. Monday for northeast winds of 15 to 25 mph, gusting to 35 to 40 mph.
- Palm Beach, Broward and Miami-Dade coasts: a coastal flood warning from 2 a.m. Monday to 8 p.m. Tuesday, with flooding expected to reach major flood stage Monday and Tuesday, NWS Miami says. Palm Beach County also faces 8- to 10-foot breakers.
- Upper Florida Keys: major saltwater flooding until 5 a.m. Tuesday, NWS Key West says. The Middle and Lower Keys are under a coastal flood advisory.
River flooding near Astor
Inland, the same northeast winds are backing up the St. Johns River. NWS Melbourne says the river near Astor, on the Lake-Volusia county line, was at 3.6 feet at 8:30 p.m. Sunday, in moderate flood stage, and is forecast to keep rising slowly early this week. The agency says canals have overflowed into yards there, docks at Astor are submerged, and some homes along the river and canals have several inches of water inside.
What forecasters expect
Every warning lists the same kinds of impacts: numerous roads may be closed, and low-lying homes, businesses and some critical infrastructure will be inundated. NWS Miami adds that coastal flood advisories will likely be needed through much of next week, after the peak of the king tides.
This is not a tropical storm. The National Hurricane Center's Sunday evening outlook says tropical cyclone formation is not expected in the Atlantic, Caribbean or Gulf during the next 7 days.
Staying safe
The Weather Service's advice in all of the warnings:
- Don't drive around barricades or through water of unknown depth. Saltwater can also damage cars.
- Move or protect anything in flood-prone spots, especially around high tide.
- Stay out of the ocean if you're not an experienced swimmer. If a rip current pulls you, relax and float, don't swim against it, and swim parallel to the shore, or face the shore and wave for help.
- Secure patio furniture and trash cans; the wind advisory warns tree limbs could come down and a few power outages may result.
