The Manhattan Beach Pier was temporarily closed on Saturday morning due to high surf and hazardous wave conditions and will be closed until further notice. 

The area has been pounded with unusually high waves, with ocean water in some cases reaching past the lifeguard stands. The city of Hermosa Beach also closed its pier on on Saturday afternoon. 

Up and down the coast of Southern California, cities are bracing for similarly high surf. The National Weather Service has issued a Coastal Flood Advisory for Los Angeles County beaches until at least 4:00 p.m. on Saturday. The NWS warns of dangerous swimming and jetty conditions; shallow flooding of seawater over low-lying beach walkways, parking lots, and roads; and potentially significant beach erosion. 

It adds a warning to "watch the big waves from a safer distance than you think." 

Due to the rains, the Los Angeles County Department of Public Health has also issued an Ocean Water Quality Rain Advisory, which urges beach users to avoid all water contact, especially near discharging storm drains, creeks, and rivers due to potentially higher bacteria levels in these areas. This includes any runoff that may flow onto or pond on the beach sand. The advisory is currently in effect until Monday morning.
