The first of two storms moved into the Southland Saturday morning and rain was forecast throughout the day for Los Angeles County.
A fairly unstable front was forecast to bring showers and some thunderstorms to Los Angeles County throughout the morning, diminishing by the afternoon, according to the National Weather Service.
Rainfall rates will be under a half-inch per hour, except under thunderstorms, where they could reach one inch per hour, the NWS said.
Most areas will see about an half-inch of additional rainfall, except for the San Gabriel Mountains, where double that amount could fall, the weather service said.
Rainfall totals were reported at just over 1/4-inch in Santa Monica, Bel Air and Getty Center. Just over a tenth-of-an-inch fell in downtown Los Angeles and at Los Angeles International Airport. Parts of the San Fernando Valley, including Pacoima Dam, Northridge, Van Nuys and Woodland Hills received between 1/4-inch and nearly four-tenths of an inch of rain as of 3 a.m., the NWS said.
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 7 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/.
Showers will continue overnight into Sunday, but the rainfall amounts will be much less and will be spotty, the NWS said. Most areas will see less than quarter-inch of rain on Sunday.
Snow will not be an issue with this system Saturday morning, with snow levels being around 7,000 feet and only an inch or two of snow is forecast above that elevation.
A wind advisory is anticipated for the mountains and interior valleys.
A second storm is forecast to bring rain to Southern California beginning Tuesday.
