Instructions

Avoid driving through flooded roadways. If you are forced to
drive through salt water, be sure to rinse your vehicle with
fresh water. Move electronics, vehicles or other valuables to
higher ground. Monitor vessels to ensure mooring lines don't get
too tight and watch out for overwash around boat ramps. Secure
canoes or other watercraft stowed on beaches.

Stay away from the shoreline along the affected coasts. Be
prepared for road closures. Postpone entering or leaving channels
affected by the high surf until the surf subsides.
