LOS ANGELES, Calif. - Rain is expected off and on throughout the weekend, according to forecasters.

Los Angeles County health officials are urging swimmers and surfers to steer clear of water near storm drains for a few days. The beach water use advisory was in effect until at least 10 a.m. Tuesday.
"Avoid swimming, surfing and playing in ocean waters around discharging storm drains, creeks and rivers," Dr. Muntu Davis said.
"Bacteria, chemicals, debris, trash and other public health hazards from city streets and mountain areas are likely to contaminate ocean waters in and around these outlets after a rainfall."
For updated beach conditions, call the county's 24-hour hotline at (800) 525-5662 or visit publichealth.lacounty.gov/beach/.
