Tsunami Advisory Issued North of San Diego County

A tsunami advisory was issued at 6:43 p.m. PDT for Orange County coastal areas north, following an 8.3 magnitude earthquake off the coast of Chile today. The National Tsunami Warning Center has determined San Diego coastal areas do not need to take action at this time. The advisory is in effect for San Onofre State Beach north to Ragged Point, which is 50 miles north of San Luis Obispo, waves are expected to be under 1 foot in height and will reach shore around 4:30 a.m. Thursday. A tsunami advisory means that a tsunami capable of producing strong currents or waves dangerous to people in or very near the water is expected. Currents may be hazardous to swimmers, boats and coastal structures and may continue for many hours after the tsunami arrival.  The first wave may not be the largest. If you are in the advisory area, move off the beach and out of harbors and marinas. Inundation of land is not expected. Do not return to the coast until emergency officials say it is safe to do so.
