What to do
Stay alert for rising water if you live near the coast in the warned area. Take action now to protect life and property. Move to higher ground if water approaches.
If you must travel, do not drive around barricades or through water of unknown depth. The National Weather Service says just 6 inches of moving water can knock you down, and 1 foot can sweep a vehicle away.
Stay out of the ocean while high surf and rip currents are in effect. Follow lifeguards, beach patrol flags and signs, especially near jetties and piers.
If caught in a rip current, relax and float. Do not swim against it. If you can, swim along the shoreline. If you cannot escape, face the shore and call or wave for help.
Context
Flood-insurance claims count only insured homes and businesses, so they understate total flood damage. FEMA records show 3,352 claims in Indian River County, 3,990 in St. Lucie County and 2,633 in Martin County since 1978.
FEMA has also issued major disaster declarations covering these counties for hurricanes, most recently Hurricane Milton in October 2024, Hurricane Nicole in December 2022 and Hurricane Ian in September 2022.
