Southern California under Tsunami Advisory

National Weather Service LogoSAN PEDRO, Calif. — The National Weather Service has issued a Tsunami Advisory for the west coast of the United States with specific applicablity to the Southern California coastline.

The Tsunami Advisory, issued this morning, is a result of an 8.9 magnitude earthquake that hit Japan early this morning. Tsunami Advisories are issued to inform the public that a tsunami capable of producing strong currents or waves dangerous to persons in or very near the water is imminent or expected.

The Coast Guard urges boaters to not get underway and check with their local harbor masters to ensure a marina evacuation has not been ordered.  Vessel owners are also urged to double-up all mooring lines.

Significant widespread innundation is not expected for areas under advisory. Currents may be hazardous to swimmers, boats, and coastal structures and may continue for several hours after the arrival of the initial wave.

Individuals located in Tsunami Advisory areas should move out of the water, off the beach, and out of harbors and marinas.

The Coast Guard strongly encourages waterfront users to take extra precautions in preparation for the possiblity of a surge.
