  • When an emergency is in the forecast...

    ...alerts need to go out to the public as quickly and as efficiently as possible. The better people are informed about a hazard threat or emergency, the more lives can be saved and resources preserved. And the more targeted the alerts are, the more people in harms way are confident the message is intended precisely for them. CAP is designed to precisely identify the alerting area and to communicate quickly and easily through any communications media, using a format that is universally readable.
