Skywarn
Please see the Nation Weather Service site for details:
The National Weather Service of the U.S. Commerce Department's National Oceanic and Atmospheric Administration, and cooperating organizations have established Skywarn Spotter Networks in order to secure critical information on severe local storms. Skywarn is an effort to save lives during severe weather emergencies by expanding networks of spotters and by encouraging the widest possible participation in tornado warning programs. There is no way to stop tornadoes, and not all tornados show up on radar, but they can be seen. Lives can be saved. Only one instrument can detect a tornado or funnel with complete certainty the human eye. More concern, more spotters, more eyes are needed. lend us yours - learn Skywarn.
