Public advised to stay out of these Los Angeles County beaches

Officials are warning the public to avoid several Los Angeles County beaches due to high levels of bacteria on Wednesday.

The ocean water warnings will remain in effect beginning Oct. 30 until further notice.

Excessive bacteria and debris can seep from nearby city streets and mountain areas to contaminate ocean waters, especially around discharging storm drains, creeks and rivers, said the L.A. County Department of Public Health.

The warning also includes any runoff that may flow onto or pond on the beach sand.

People who enter the ocean during this time could become ill, especially children, the elderly or those who are immunocompromised, officials said.

The public is asked to stay out of these L.A. County beaches:

• Mothers Beach in Marina Del Rey - The entire swim area
• Santa Monica Pier in Santa Monica - 100 yards up and down the coast from the pier
• Outer Cabrillo Beach in San Pedro - 100 yards from the lifeguard station

The health department tests ocean water bacteria levels regularly and advisories will be lifted once the levels meet standards set by the state of California.
