Some NOAA Weather Radio (NWR) stations broadcast tsunami warnings and alerts. The maps below show the tsunami alerting areas and nearby stations that provide these warnings and alerts for the corresponding regions.

Tsunami alerts broadcast over NWR include Tsunami Watches, Advisories, and Warnings. The National Weather Service (NWS) has created maps of NWR coverage overlaid with existing tsunami alerting areas, which correspond to NWS public weather forecast zones. Tsunami alerting areas are displayed in pink, while NWR broadcast areas are shown in green.
