The Santa Monica Beach Pico-Kenter storm drain was moving rapidly beginning early Tuesday, carrying with it debris and bacterial contamination. The storm drain and other runoff into the ocean mean surfers and swimmers are cautioned to avoid entering the water for at least 72 hours after rain subsides.

The LA County Department of Public Health issued an Ocean Water Quality Rain Advisory for all Los Angeles County beaches, advising beachgoers to avoid the water through at least 7:30 a.m. on Friday, Dec. 17.

“Bacteria levels can increase significantly during and after rainstorms, as contaminants within the runoff enters the ocean. 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,” the advisory stated, adding that bacteria levels are especially high “near flowing storm drains, creeks and rivers.”
