Beach-goers should steer clear of storm drains and water flow from creeks and rivers during this week's storms due to potential bacteria or chemicals from debris and trash, health officials warned.
A rain advisory for all Los Angeles County beaches will be in effect through at least Wednesday, according to the Los Angeles County Department of Public Health.
"We advise swimmers and surfers to stay away from the storm drains, creeks and rivers, as there is the possibility that bacteria or chemicals from debris and trash may contaminate the water near and around these areas, and some individuals may become ill," Public Health Director Jonathan Fielding said in a statement.
"Fortunately, discharging storm drains, creeks and rivers only comprise a small portion of the beach, and therefore a large portion of the beach remains accessible," he added.
The advisory could be extended, officials said, if there is more rain later in the week.
