Sierra Madre Returns to Green Flag Alert

City of Sierra Madre returns to Green Flag Alert

The City of Sierra Madre has returned to a Green Flag Alert. The County of Los Angeles Public Works has rescinded the Phase 1 mudflow forecast. The National Weather Service is forecasting between 60 and 100% precipitation for the rest of today.

Parking restrictions have been lifted for all parts of the City.

City of Sierra Madre’s three-color Flag Alert System:

GREEN FLAG - Activated under a prediction of 80% - 100% chance of precipitation. Affected residents should get “READY” for potential evacuation. This includes keeping a close watch on weather forecasts.

YELLOW FLAG - Activated with an LA County Phase 1 mudflow forecast, or deemed consistent with the County’s forecast thresholds. This is described as small, isolated debris and mudflows possible at specific locations. Affected residents should get “SET” to leave their homes and may choose to voluntarily evacuate. Please note that all vehicles must be off the streets in potential mudflow areas during Yellow Flag alerts.

RED FLAG - 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 “GO”, meaning they should immediately evacuate, and vehicles should not be parked on the streets.
