According to the National Weather Service, the subtropical moisture will hang around Southern California through Friday night, bringing periods of rain. Most areas should expect up to 1 inch of additional rain overnight.
NWS also says spurts of rain are expected through Saturday morning, with the majority of rainfall in Los Angeles and Ventura counties. Snow levels will remain at the higher elevations, and a new, colder weather system will bring another chance of showers by Sunday.
But the weekend storm isn't putting a damper on locals. For people in Long Beach, shoppers still braved the weather in Belmont Shore on Friday. Other people looking to be outdoors instead took a trip to the Aquarium of the Pacific.
"It's a little less crowded on rainy days," said Margie Drilling of Fountain Valley. "I thought we were going to go for a hike, but then I thought we'd come down to Long Beach instead because of the rain."
However, it hasn't been all fun and games. The morning commute was an absolute mess with hundreds of accidents tying up roads across the region.
The biggest incident happened around 12:20 a.m. Friday on the 101 Freeway at Highland Avenue in Hollywood. Officials said six separate accidents involving a total of 16 vehicles occurred in the same area.
There was a solo-vehicle accident and then five subsequent crashes. At least six people were transported to the hospital. One person sustained critical injuries.
The six accidents shut down all southbound lanes for a couple of hours. Authorities said alcohol was not a factor in any of the crashes.
On the eastbound 91 Freeway at Harbor Boulevard, two people were injured in a three-vehicle crash just after 1 a.m. Officials said rain may have been a factor.
A big rig jackknifed on the 105 Freeway in Lynwood late Thursday night, but no injuries were reported in that crash.
These incidents were just a few of the hundreds of accidents in the Los Angeles area on Friday. This has some residents griping about L.A. drivers.
"A lot of Californians have a tough time navigating the rain, so a lot of people are slowing down at the wrong times - not as early as they should or way earlier than they need to," said Silver Lake resident Clay Westervely.
There was more trouble earlier on the 101 Freeway in Boyle Heights at Mission. A white pick-up truck overturned possibly because of the wet roads. Two lanes were blocked and traffic was backed up for hours.
Then on the 10 East at Santa Fe in Los Angeles, traffic was tangled up by another possible rain related accident. A small car crashed under a big rig trapping the driver of the car. That person was transported to a local hospital.
And with rain still falling across most of SoCal, many drivers say they are preparing themselves for a tough Friday evening commute and plan to be extra cautious on the roads.
"Just keep in mind the speed limit, basically just watch where you're going, keep your distance between cars," said South Pasadena resident Bill Lavoie.
