What happened
The episode as NWS LOX wrote it up.
A powerful Pacific storm brought snow and rain to Southern California. The storm produced 10 to 16 inches of snowfall in the mountains. In fact, snow levels dropped to near 2000 feet which resulted in the closure of many mountain highways, including Highways 14 and 33. Unstable air, associated with the storm, generated heavy showers. These heavy showers produced widespread street flooding across Los Angeles County.
