What to do
Take steps now to protect flood-prone property, as the National Weather Service advises. Move valuables and important items to higher levels if you can do so safely.
Avoid travel if you can. 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 of moving water can sweep a vehicle away.
Move to higher ground if water approaches your location. Expect low-lying homes, businesses and some critical infrastructure to be inundated, and expect some shoreline erosion.
