A beach advisory has been issued for all Los Angeles County beaches, including Manhattan Beach, meaning that beach users should avoid contact with ocean water until given the all clear.

The beach advisory was released due to significant rainfall that may cause bacteria levels in ocean waters to increase.

The current advisory is expected to last at least through 10:00 a.m. on Thursday, March 31, unless significant additional rainfall occurs, in which case the advisory may be extended.

Bacteria levels can increase significantly during and after rainstorms, as contaminants within the runoff enters the ocean, according to the Los Angeles County Department of Public Health. Bacteria levels may remain elevated up to 3 days depending upon the intensity of the rain and the volume of runoff. Elevated bacteria levels in ocean water may cause illness, especially in children and the elderly.

Recorded information on beach conditions is available 24 hours a day on the county's beach closure hotline: 1-800-525-5662. Information is also available online at PublicHealth.LACounty.gov/Beach/
