Frequently Asked Questions (FAQ)

How will I be notified if a forecasted rain event could potentially flood my area?

Alert and warning is performed by law enforcement. The Sheriff's Department has tools to provide advance notification to residents and businesses. Whenever possible, one or more of these tools may be used during any disaster. The tools include media press releases/press conferences, Emergency Alert System (formerly known as the Emergency Broadcast System) broadcasts, door-to-door notifications, and Alert LA.

Alert LA is a mass notification system that uses phone calls, emails and text messaging to alert impacted residents and businesses. To learn more about Alert LA or register mobile devices, email addresses, and alternative telephone numbers, visit alertLA
