Skywarn™ Spotters and General Public

Skywarn™ Spotters are an important asset to the NWS. We ask our Spotters to provide us reports of

many different kinds of severe weather.

If you are a Skywarn™ Spotter the best way to contact us is by using the "800" number provided on your Skywarn™ card.

Skywarn™ Spotters and the public can also provide us reports in other ways.
