Weather Radars

As part of the modernization of the National Weather Service (NWS), the NWS has been replacing its aging network radars, the Weather Surveillance Radar 1957 (WSR-57) and WSR-74, with the Weather Surveillance Radar 1988 Doppler or WSR-88D. This is also known as the NEXt generation RADar or NEXRAD. Unlike its predecessors, the WSR-88D is equipped with computers to generate images and analysis that were not available with the older radar systems. The WSR-88D has a number of advantages over the old system. It is more powerful than older radars, has better resolution, and improved clutter suppression, and it performs volume scanning of the atmosphere to paint a 3 dimensional picture of storms. Some of the computer generated images include, storm tracking information, Doppler velocity images, and rainfall accumulation estimates, to name a few. Additional information can be found at the bottom of this page. Note: Picture to the left shows the KBMX radar tower and dome.

There are currently four WSR-88D radars operating in Alabama which are used in detecting and tracking dangerous storms, as they move across Alabama and West Central Georgia. These include:
