What is SKYWARN?

SKYWARN is part of the National Weather Service’s warning program designed to establish a network of volunteers trained in the detection and reporting of life-threatening storms. Although advances in computers and communication networks have made great strides over the past several years, only one instrument can detect tornadoes with complete certainty - the human eye. We rely heavily on the reports that we receive from our 1300 pairs of our spotters eyes!

What will I learn at a Skywarn class?
By taking the SKYWARN spotter course you will learn about the meteorological dynamics involved in thunderstorm development, and ingredients necessary to make a thunderstorm severe or tornadic. You will also learn what features to look for when viewing thunder - storms. The reports that we receive from our spotters may help us to save the lives of your neighbors, family members, and even complete strangers in the next town.

What if I have already been to a Skywarn class?
Due to the fast pace of technology and the new understanding of thunderstorms, we ask that you try to attend a SKYWARN class annually. This year’s presentation will again feature an UPDATED multimedia presentation. You will see awesome photography and exciting video. The class usually lasts about an hour and a half. The ID number you will be given will only be valid for four years. The classes are FREE and open to everyone interested.
