Fire Weather Planning Forecast for Wrn Colorado and Ern Utah
National Weather Service Grand Junction CO
112 AM MDT Sun May 17 2026

.DISCUSSION...Critical fire weather conditions will be replaced
by a wetter regime over the next few days as a stronger system
works through the Rockies. One concern will continue to be 
strong outflow winds from virga/showers and the threat of these
winds occurring with the threat of lightning and new fire starts.
Otherwise areas outside of the 4 Corners region have a high 
probability of wetting precipitation over the next few days.
Unfortunately in the 4 Corners region little precipitation is 
expected with this storm. 

...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
