What to know about Wireless Emergency Alerts

We send Wireless Emergency Alerts (WEAs) on behalf of federal, state, or local emergency management agencies. These are free notifications that have a special tone and vibration.

Each WEA broadcasts at a set volume that can’t be changed. These alerts don’t interrupt phone calls, sending emails, or other online transactions. But they may override any blocks you have on your phone, like do not disturb.

If you get a WEA, take any recommended action and check your local media or the National Weather Service for more details.

Alert Types

There are 4 types of Wireless Emergency Alerts:

  • Imminent threat alerts warn of severe weather or other disasters that pose a threat to life or property.
  • Public Safety messages are related to imminent threats and prescribe one or more actions likely to save lives or safeguard property
  • AMBER alerts notify communities about missing children.
  • Presidential alerts are issued by the U.S. president. You can't opt-out of this type of alert.

In addition, the following alert types may be received as an Imminent threat or AMBER alert type, depending on the sending agency policy:

  • Silver alerts for missing older adults with dementia or Alzheimer’s
  • Blue alerts to help capture violent criminals who kill or seriously wound federal, state, or local law enforcement officers
  • Endangered Missing Persons alert for someone missing with an intellectual disability

  • You aren't in an area targeted to get an emergency alert.
  • Your phone was turned off or was in use when the alert was sent.
  • Your phone isn’t running the latest software. Learn how to update it.
