A tsunami advisory has been issued from Ragged Point in northern San Luis Obispo County to San Onofre State Beach in north San Diego County after a powerful magnitude 8.3 earthquake hit off the coast of Chile Wednesday night.
The Pacific Tsunami Warning Center issued the advisory for a 300-mile stretch of California Coast at 7:38 p.m. A tsunami is expected to arrive in the Port San Luis area at about 5:10 a.m. Thursday, according to the advisory.
Strong currents or waves dangerous to people in or very near the water are expected and could remain a hazard for many hours after the tsunami arrival, according to the advisory. Currents may be hazardous to swimmers, boaters and coastal structures. The first wave of the tsunami may not be the largest, the advisory notes.
The Pacific Tsunami Warning Center recommends staying off the beach and out of harbors and marinas, although widespread inundation on the land is not expected. The public should be alert to instructions from local emergency officials, the advisory said.
