Yesterday, Los Angeles and surrounding areas in southern California (SoCal) experienced flooding, mudslides, and debris flows following heavy and intense rainfall from a stronger-than-predicted AR Storm. Today, flood waters are receding as the storm moves out of the area. Currently, streamflows in SoCal are elevated, and one flood forecast point remains above flood monitor stage. Yesterday, 5 sites in SoCal experienced highest ever streamflow for that day of year, and today, 13 sites remain above the 90th of flow for the date.

Today, the California Water Science Center has 11 crews from Redlands, CA (5) and Poway, CA (6) service areas deployed for flood response, streamflow verification, water-quality sampling, and new station rating development. No crews are expected to deploy tomorrow . Currently, all streamgages are transmitting data. No gage damage or safety issues have been reported.
