A National Oceanic and Atmospheric Administration (NOAA) Weather Radio is a dedicated radio that receives real-time weather information direct from the National Weather Service. Routine weather messages are typically repeated every 4 to 6 minutes and are updated every 1 to 3 hours. During severe weather, more frequent updates and live broadcasts are used to notify listeners of potential hail, flooding, tornadoes, blizzard conditions, and other weather warnings. Newer radios can be set to play county-specific alerts. NOAA Weather Radio broadcasts can usually be heard as far as 40 miles from a transmitter, although a good quality antenna may be needed for reliable reception in some urban areas.
NOAA - Weather Radios can be purchased at many electronic stores.
