The California Highway Patrol logged 115 crashes between 4 a.m. and 9 a.m., compared with 55 during the same time period a week ago, when it did not rain, said officer Ed Jacobs.
In Pasadena, a big rig jackknifed while making the transition from the westbound 134 Freeway to the 210 Freeway. The driver wasn't hurt, but the semi busted through the guardrail and blocked the onramp for several hours.
"It looked like he may have lost some traction," said CHP Sgt. Marcy Rangel. "It's still under investigation of course, but when he was on the transition road the trailer of the truck started to fishtail or started to lose traction somehow."
The rain also made some back roads in the Angeles National Forest too muddy to navigate, stopping an SUV in its tracks. Firefighters, with the help of a search helicopter, were able to locate SUV and rescued the four passengers. One person was treated for minor injuries.
The winds also caused problems for residents. As of 11 a.m., about 1,400 LADWP customers were without power due to downed trees.
The rain was expected to start clearing up Thursday afternoon with temperatures in the mid-60s in the Los Angeles-Metro area, Orange County, Inland Empire, Valleys and High Desert. The local mountains will see highs in the upper 40s.
