Alerts And Warnings


Receiving timely information about weather conditions or other emergency events can make all the difference in knowing when to take action to be safe. Local police and fire departments, emergency managers, the National Weather Service (NWS), the Federal Emergency Management Agency (FEMA), the Federal Communications Commission (FCC), the National Oceanic and Atmospheric Administration (NOAA), and private industry are working together to make sure you can receive alerts and warnings quickly through several different technologies no matter where you are–at home, at school, at work, or in the community.

For those with access and functional needs, many messages are TTY/TDD compatible and many devices have accessible accommodations. Review this page to make sure you will receive critical information as soon as possible so you can take action to be safe. Be sure to share this information with your family, friends, and colleagues. And remember to keep extra batteries for your mobile phone or radio in a safe place or consider purchasing other back-up power supplies such as a car, solar-powered, or hand crank charger


Organized by FEMA, the Integrated Public Alert and Warning System (IPAWS) is the Nation’s alert and warning infrastructure. It provides an effective way to alert and warn the public about emergencies using the Emergency Alert System (EAS), Wireless Emergency Alerts (WEA), NOAA Weather Radio All Hazards, and other public alerting systems from a single interface. IPAWS is used to send notifications for three alert categories— Presidential, AMBER, and Imminent Threat.

Using IPAWS, officials can send messages simultaneously through multiple pathways, including:

    • EAS: used by alerting authorities to send detailed warnings to broadcast, cable, satellite, and wireline communication pathways;
    • WEA: Free, 90-character emergency text messages sent by local alerting authorities to equipped mobile devices within range of cell towers broadcasting in the affected area. You do not have to sign up for WEA alerts. To find out if your mobile device is capable of receiving WEA alerts, contact your cellular service provider or visit; and
    • IPAWS compliant digital road signs, sirens, and other systems.

Note: For more information on IPAWS, EAS, and WEA, visit


The NOAA Weather Radio All Hazards, or NWR, is a nationwide network of radio stations broadcasting forecasts, warnings, and emergency information 24 hours a day. It is a comprehensive weather and emergency information service available to the public. All-hazards messages include weather events, technological incidents like chemical spills, AMBER alerts, and national emergencies. NWR also broadcasts EAS notices.

A special weather radio receiver is required to receive NWR broadcasts. You can buy these receivers at many retail outlets such as electronics stores, department stores, big box stores, or online. Be sure to look for the Public Alert or NWR logo to ensure the radio meets technical requirements. Models identified as SAME, or Specific Area Message Encoding, receivers allow users to select alerts for specific geographic areas. For information on NOAA Weather Radio All Hazards, visit
