    water.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Conditions favorable for coastal flooding are expected to
    develop. Coastal residents should be alert for later statements
    or warnings and take necessary actions to protect flood-prone

    Rip currents are powerful channels of water flowing quickly away

    sandbar and in the vicinity of structures such as jetties and
    piers. Heed the advice of lifeguards, beach patrol flags and
    signs.

    Entering the surf is strongly discouraged. If caught in a rip
    current, relax and float. Don't 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.
