NOAA Weather Radio All Hazards



NOAA Weather Radio (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service Office. NWR broadcasts official weather service warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week.

NOAA Weather Radio includes signals which trigger alert features on specially equipped receivers when warnings are posted on dangerous storms. In some cases, the receiver is automatically turned on, in others the receiver sounds a loud tone to alert listeners to the special weather bulletin being aired.

Weather Information for DeSoto County is broadcast on 162.475 MHz from Memphis, TN and 162.400 MHz from Oxford, MS.

Newer modern NOAA radios include a feature called Specific Area Message Encoder (S.A.M.E.). This system uses digital technology to allow listeners to select the specific weather threat and specific area for which they want to be alerted. The six digit S.A.M.E. Code for DeSoto County is 028033.

Alert FM



Alert FM is an FM radio based system used for mass notification. Emergency information is delivered via the data sub-carrier of existing FM radio stations, SMS (text) and email. This personal alert and messaging system allows emergency management officials to create and send digital alerts and messages to recipients such as first responders, school officials, businesses, and citizens based on geographic or organizational groupings. Such alerts and messages might include NOAA weather warnings,evacuation instructions, homeland security notices, amber alerts, or school closings.

Alert FM receivers have been placed in DeSoto County schools, office buildings and other public access areas to provide emergency information.
