Latest News About National Weather Service Radio Frequency

Here’s the latest I can share based on up-to-date public information.

• NOAA Weather Radio (NWR) uses seven VHF frequencies for national broadcasts: 162.400, 162.425, 162.450, 162.475, 162.500, 162.525, and 162.550 MHz. These are the standard frequencies you’ll find for NWR transmitters nationwide.
• NWR is a nationwide network of over 1,000 transmitters that provide continuous weather information, watches, warnings, and forecasts for the U.S. and territories.
• In 2025, NOAA and partner broadcasters conducted rolling updates and maintenance across many stations, which could cause temporary outages or periods of offline status while updates are completed. If you’re relying on NWR during severe weather, it’s wise to have a backup alerting method during maintenance windows.
• For a quick reference, many local NWR brochures list the seven frequencies above and note that you’ll need a dedicated NWR weather radio or scanner to receive alerts. This is standard nationwide guidance.

Illustrative example: If you want to program a weather radio for a typical U.S. location, set it to the seven NWR channels (162.400, 162.425, 162.450, 162.475, 162.500, 162.525, 162.550 MHz). It will broadcast alerts from NOAA’s National Weather Service for your county or nearby areas.
