Integrated Public Alert & Warning System (IPAWS)

Federal Emergency Management Agency (FEMA) built IPAWS to ensure that under all conditions the President of the United States can alert and warn the American people. Federal, state, local, tribal, and territorial authorities also have the opportunity to use IPAWS to send alerts and warnings within their jurisdictions. IPAWS improves alert and warning capabilities by allowing alerting authorities to deliver alerts simultaneously through multiple communications devices reaching as many people as possible to save lives and protect property. These communication pathways include:

The City of Aliso Viejo has the ability to send Wireless Emergency Alerts (WEA) to the public in addition to the Orange County Emergency Management Division, California Office of Emergency Services, and FEMA. All other local IPAWS alerts are disseminated by the Orange County Emergency Management Division, California Office of Emergency Services, and FEMA.
