Online spotter training available: The Cooperative Operational Meteorology Education and Training (COMET) offers an online Skywarn® Spotter Training course in two sections: "Role of the Skywarn® Spotter" and "Skywarn® Spotter Convective Basics". The course is designed for people interested in becoming storm spotters.  While previously-trained Skywarn® spotters are not required to take it, it does provides additional background material not covered in the local classes. The course is free and each section takes one to two hours to complete. People interested in becoming spotters for the National Weather Service can notify our office after completing the training.

In-person classes will not be held this year due to COVID-19 travel restrictions and social distancing guidelines. Instead, we will offer several virtual classes via webinar.
