This Hazardous Weather Outlook is for northwest Colorado, southwest
Colorado, west central Colorado, east central Utah, northeast Utah
and southeast Utah.

.DAY ONE...Today and tonight.

Monsoonal moisture will remain over the area providing the means
necessary for thunderstorm development. Some of these storms this
afternoon will be capable of producing hail bigger than dimes and
wind gusts over 50 mph. The main threat however will be rainfall
rates over 1"/hr that could produce excess runoff and flooding. The
flooding threat will linger through overnight hours along with
thunderstorm development especially over southwest Colorado and
southeast Utah.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Thunderstorm development...with hail...gusty winds and heavy
rainfall...remains a threat into Monday before the monsoonal moisture
plume is pushed out of the area by drier air. Isolated afternoon
thunderstorm development will be possible over the southern mountains
through mid week. As the drier air becomes more entrenched late in
the week...elevated fire weather concerns will be possible.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed the next few afternoons due to the
threat of flooding and stronger thunderstorms.
