Colorado All-Season Spotter Team

Weather reports from spotters will help save lives and property during the years
to come. The volunteer spotter team is an essential part of the warning decision process
of the National Weather Service. Ground truth reports from spotters are used in
conjunction with Doppler radar, satellite, and other sources to determine the need
for weather warnings and advisories.
We are continuously recruiting spotters living in Northeast Colorado, and across
the Northern mountains, Front Range Foothills, and high mountain valleys.  If you
are a weather enthusiast and enjoy measuring rain and snowfall, or you find yourself
drooling at the bit for severe weather, this team is for YOU! Folks living in
mountain locations such as Jackson, Grand, Summit, Larimer, and Park counties are
especially needed! 

Typical reports you would provide include;  snowfall, snow depth, freezing rain,
dense fog,   high winds, and road conditions. Examples of summertime weather
reporting would include information on tornadoes, hail,  heavy rainfall and
A dedicated, toll free number is available to call the National Weather Service in     
Boulder, 24 hours a day, 7 days a week. Reporting can also be done on your
computer  via the Denver/Boulder Home page to submit weather reports.
