Classes are free and open to the public, but some may require advanced registration. You do not need to be a resident of the county in which a talk is being held in order to attend. Each class lasts about 1.5 to 2 hours and is led by a National Weather Service meteorologist who will discuss techniques and safety for severe weather spotting. Once you attend a class, you are an officially trained spotter and can report severe weather to your NWS office. Click here for a link to all classes offered for Spotter Training.
