LOS ANGELES (CNS) — Los Angeles County health officials Wednesday issued their standard warning for people to avoid swimming in the ocean due to the possibility of contaminated stormwater runoff carried to the coast following Tuesday's rain storm.

The Department of Public Health issued a beach water use advisory that will be in effect until noon Saturday, urging people to avoid swimming, surfing or playing in ocean water, particularly near discharging storm drains, creeks and rivers.

Health officials stressed that stormwater runoff can be contaminated with bacteria, chemicals, debris, trash and other health hazards.
