skywarn

We offer sets of online basic spotter courses and one advanced spotter course each spring and fall, usually February into March and again in October, leading into our regional climatological increases in severe weather. These online courses are FREE and allow individuals to complete the course(s) in the comfort of their home or office using GoToWebinar. By attending any course, which runs about 2 hours, an individual or group of individuals will become a SKYWARN storm spotter.

Unless you'd like to or are in need of a refresher, which we recommend, you do not have to attend more than one basic course as the material covered is the same; however, we require you to attend at least one basic course before taking the advanced course. These courses are two-way, meaning you will be able to interact with the NWS meteorologist leading the training. You will be muted while training is in progress, but you may use the built-in feature to ask questions.

Note: A spotter class may be cancelled or rescheduled if affected by active weather.

How to Attend an Online Storm Spotter Class

1. Via the schedule below, register by clicking the link corresponding to the class you'd like to attend.

is expected to be posted by early February.

SKYWARN is the National Weather Service (NWS) program of trained volunteer weather spotters. Storm spotters come from many walks of life, including fire fighters, law enforcement, amateur radio operators, and the public. SKYWARN storm spotters provide important ground truth information to NWS warning forecasters who make critical warning decisions during severe weather, and help the NWS perform its primary mission to save lives and property.

Note: This is not storm chaser training. A storm spotter is a volunteer service that is conducted primarily from fixed locations such as from home, work, or around your community. The National Weather Service does not endorse or encourage the use of storm spotter training for storm chasing.
