PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Coastal Flood Warning means that moderate or major tidal

Follow the recommendations of local emergency management
officials.
Do not drive your vehicle through flood waters. The water may be
deeper than you think it is. You will be putting yourself in
danger and your vehicle may be damaged, leading to costly
repairs.
Visit the Advanced Hydrologic Prediction Service at
water.weather.gov/ahps for additional water level and flood
impact information for your local tide gauge.
Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.
Always obey posted Beach Flags. If you enter the surf zone,
always have a floatation device with you and swim near a
lifeguard if possible. If caught in a rip current, relax and
float and do not swim against the current. If able, swim parallel
to the shoreline. If unable to escape, face the shore and call or
wave for help.
