What to do
Take the necessary actions to protect flood-prone property. 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 of moving water can sweep a vehicle away.
If you are near the coast, swim near a lifeguard. The National Weather Service also has a High Rip Current Risk in effect through Sunday evening.
If caught in a rip current, relax and float. Do not swim against the current. If able, swim along the shoreline. If you cannot escape, face the shore and call or wave for help.
