The National Weather Service in Los Angeles/Oxnard has replaced a High Surf Advisory with a Beach Hazards Statement for elevated surf and strong rip currents, which is in effect through Sunday afternoon. The High Surf Advisory has been cancelled. * SURF...Surf of 3 to 6 feet with local sets to 7 feet will affect exposed south facing beaches through Sunday afternoon. Strong and dangerous rip currents will be likely with this event. There is the potential for an extended period of elevated to high surf conditions and strong rip currents beginning Tuesday and continuing into Thursday as computer models show that Hurricane Sergio may return into our surf window. * TIDE...Minor coastal flooding and beach erosion is possible near times of high tide. Los Angeles Harbor experienced it's peak high tide of 6.5 around 8 to 8:30 pm this evening. The tide will be lowering through the rest of this evening and overnight hours. * Impacts...There is an increased risk for ocean drowning. Rip currents can pull swimmers and surfers out to sea. Sneaker waves can suddenly wash people off of beaches and rock jetties. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Beach Hazards Statement is issued when threats such as rip currents...longshore currents...sneaker waves and other hazards create life-threatening conditions in the surf zone. Swim near a lifeguard. 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. && $$ Kaplan/Hall
