What to do
Take steps now to protect flood-prone property. The National Weather Service says low-lying homes, businesses and some critical infrastructure will be inundated, and numerous roads may be closed.
If you must travel, 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.
Inexperienced swimmers should stay out of the water. If you swim, stay near a lifeguard.
If caught in a rip current, relax and float. Do not swim against it. If able, swim along the shoreline. If you cannot escape, face the shore and call or wave for help.
