The Norman Weather Forecast Office maintains twelve NOAA Weather Radio transmitters across Oklahoma and one in western north Texas to transmit routine extended and specialized short-term forecasts, current weather observations, hazardous weather outlooks and historical weather information.
Each of the transmitters, through the Emergency Alert System, also disseminate watches, warnings and advisories issued by the NWS office, severe thunderstorm and tornado watches issued by the Storm Prediction Center and other emergency information to the public.

The office schedules a required weekly test of the Specific Area Message Encoding system for public alert dissemination on all thirteen NOAA Weather Radio transmitters in the region each Wednesday at 12:00 and 7:00 p.m. Central Time; exceptions exist if there is a threat of severe weather that day within the listening area of any or all of the stations, in which case the test will be postponed until the following Wednesday, barring that severe weather is not forecast to occur then.
