It's a dream come true for surfers, with large waves and high surf expected to pound much of the Southern California coastline Thursday and into the weekend; but forecasters warn the conditions could be dangerous and raise the risk of flooding.
"This tremendous wave energy entering the coastal waters will generate extremely dangerous conditions at the beaches (Thursday) morning through this weekend," according to the National Weather Service. "... Swell heights and periods will drop off briefly (Thursday night) into Friday, before the next strong wave front arrives for this weekend.''
Forecasters said the conditions will have "coastal flooding impacts" through Saturday.

A high surf advisory and coastal flood advisory will be in effect until 10 p.m. Saturday for all Los Angeles County beaches, including Catalina Island. According to the NWS, waves of 7 to 12 feet are anticipated, accompanied by dangerous rip currents. Hermosa Beach, Manhattan Beach and Palos Verdes Beach could see localized sets of 15 to 20 feet.
"Flooding of sea water is likely, around the time of high tide, over vulnerable low-lying coastal areas such as parking lots, beaches, and walkways," according to the NWS. "Significant damage to roads or structures is NOT expected. There is an increased risk for ocean drowning. Rip currents can pull swimmers and surfers out to sea. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore."
