What to do
Do not drive into flooded roads. The National Weather Service says to turn around, don't drown, because most flood deaths occur in vehicles.
Move to higher ground if you are in a low-lying area or near a creek or stream. Never drive around barricades.
Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away. Stay away from underpasses and streets with water on them.
Keep checking National Weather Service updates until the warning ends at 9:30 AM CST.
Context
FEMA flood-insurance records show 1,484 claims in Acadia Parish between 1978 and 2026, and 313 claims in Jefferson Davis Parish between 1979 and 2022. These counts cover only insured properties, so they do not show all flood damage.
Both parishes were included in five recent FEMA disaster declarations, from Hurricane Laura in August 2020 to Hurricane Ida in August 2021. They also include Hurricane Delta, Hurricane Zeta and severe winter storms.
