What to do

Protect flood-prone property now. Move valuables and vehicles away from the shoreline and tidal waterways if you can do so safely.

Avoid travel in low-lying areas near the water. If you must go out, do not drive around barricades or through water of unknown depth. Just 6 inches of moving water can knock you down, and 1 foot can sweep a vehicle away.

If water is rising near your home or business, move to higher ground. Check NWS updates until the warning ends or is changed.

Context

All three counties were included in FEMA disaster declarations for Hurricane Sandy in 2012 and Hurricane Irene in 2011. Dorchester County also had a declaration for Tropical Storm Isaias in 2021.
