Although the rain has stopped, officials say the ground is still slippery on Thursday morning.
One driver lost control on the transition road from the northbound 110 Freeway to the eastbound 91 Freeway at about 11:15 p.m., rolling the vehicle. No other vehicles were involved in the accident, and no one was injured.
In West Whittier, a truck flipped over on the East Washington Boulevard onramp to the 605 Freeway just after midnight. No one was injured in the crash, but again, slick roads may be to blame.
From Long Beach to downtown Los Angeles, steady rainfall fell overnight. In the San Gabriel Valley, rain brought puddles to parking lots and shopping centers.
