This Hazardous Weather Outlook is for the western two thirds of
Utah and southwest Wyoming.

.DAY ONE...Today and Tonight

An increasing southwest flow combined with low relative humidity
will produce critical fire weather conditions over west central
Utah this afternoon and evening.

With the first in a series of upper level disturbances crossing
the northern Great Basin, scattered showers and thunderstorms can
be expected this afternoon. Gusty winds will be possible with the
storms.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Moisture will increase across the region on Tuesday, and then remain
in place on Wednesday, supporting shower and thunderstorm
potential. The storms may produce heavy rain, and as such, there
will be a potential for flash flooding, especially across flood
prone areas such as slot canyons, dry washes, and burn scars.

.SPOTTER INFORMATION STATEMENT...

Weather spotters are encouraged to report significant weather
conditions according to standard operating procedures.
