Two right lanes on the southbound 5 Freeway at Empire Avenue in Burbank were expected to remain closed until at least 7 a.m., also due to flooding in lanes.

The slippery roads made for dangerous driving all over Southern California. Late Sunday night, an LAPD motorcycle officer was taken to a hospital with a non-life threatening injury after colliding with a car in Mid-City. In Sylmar, a driver escaped unscathed after losing control of his car and plunging off the 5 Freeway, tumbling five times before landing on the street below, while in North Hollywood, a car overturned along the southbound 170 Freeway at Sherman Way just after midnight. No one appeared to have been hurt in either crash.
