Emergency Alert System (EAS)

Emergency Alert System (EAS)

NOAA Weather Radio All Hazards (NWR) is a major part of the Emergency Alert System (EAS) that disseminates critical warning information rapidly through commercial broadcast outlets. In an emergency, each NWR station will transmit a warning alarm tone signal followed by increasing volume or producing a visual and/or audible alarm. Though not all weather band receivers have the capability, all weather radios can receive the emergency broadcasts.
