PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing rip currents and localized beach
erosion.

A Coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in
sandbars and near structures such as groins, jetties, and piers.
Talk to lifeguards and beach officials to learn about any surf
hazards and heed their advice. Pay attention to flags and posted
signs and swim in life guarded areas.

Swim near a lifeguard. If caught in a rip current, relax and
float, and do not swim against the current.  If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.
