Sierra Madre issues Red Flag for mud flow and urban flooding

The rain moved into the area hard and heavy about an hour ago here in the Foothill Cities.  I”m about 2 miles east of Sierra Madre and we have had about 1″ of rain since it started raining around 4AM.  Sierra Madre has issued Red Flag alerts with voluntary evacuation.  All the info needed on the evacuations can be found on the Sierra Madre city web.  

The exact verbage on the warning from their web:

The City’s state of emergency level is now at the Stage 3 – RED FLAG. This was activated with an LA County Phase 2 or 3 forecast. Phase 2 includes moderate debris and mudflows at more widespread locations. Phase 3—the potential exists for significant debris and mudflows to be widespread. Affected residents should get SET to leave their homes and may choose to voluntarily evacuate. Vehicles should not be parked on the streets.
