Skywarn™ Meeting Schedule

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.

ESpotter and the automated phone system enable Severe Weather Reporting for Skywarn™ Spotters, and the general public. Your severe weather reports reach forecasters in real time and, after quality control, may be included in a Local Storm Report(LSR) product. Information included in Local Storm Reports is also plotted on a map.

Use these maps to see the latest storm reports.
