What to do

Do not drive through flooded roads. The National Weather Service says most flood deaths occur in vehicles. Never drive around barricades.

If water is rising where you are, move to higher ground. Stay away from small creeks and streams, underpasses and low-lying areas, which the warning lists as at risk.

Use extra caution after dark, when flood dangers are harder to see. The National Weather Service notes that just 6 inches of moving water can knock you down, and 1 foot can sweep a vehicle away.

Context

FEMA flood-insurance records show 2,633 claims in Martin County and 3,990 in St. Lucie County since 1978. These counts cover only insured properties, so they understate total flood losses.

Both counties have been included in FEMA disaster declarations for hurricanes, most recently Hurricane Milton in October 2024. Earlier declarations include Nicole, Ian, Dorian and Irma.
