Severe Storm Spotter Training gives an individual the basic tools you need to be a severe weather spotter. Starting with a blue sky, individuals are taught the basics of thunderstorm development, storm structure, what features to look for and where to find them. What and how to report information and basic severe weather safety are also covered. The class is a multi-media presentation using still pictures and video. The class typically takes from 2 to 2 1/2 hours. You will only need one class by the National Weather Service, to become a volunteer storm spotter.
