Instructions:

Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Inundation above ground level refers to the height above the Mean Higher High Water (MHHW) level. Beachgoers should never turn their back on the ocean and remain alert to surf conditions. Avoid walking on area beaches and jetties. Large Waves may cause serious injury or sweep people into dangerous seas. Those participating in razor clam digs this weekend should exercise caution.
