FIRE WEATHER PLANNING FORECAST FOR WRN COLORADO AND ERN UTAH
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
137 PM MDT SUN SEP 27 2026
DISCUSSION
A FEW ISOLATED SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS
AFTERNOON, MOSTLY OVER THE HIGH TERRAIN. THIS EVENING SHOWERS ARE
EXPECTED OVER THE CENTRAL AND NORTHERN DIVIDE. A STRONG PUSH OF
MOISTURE WILL ALLOW FOR WIDESPREAD PRECIPITATION MONDAY AND
TUESDAY. PROLONGED RAINFALL IS POSSIBLE, WHICH INCREASES CONCERNS
OF FLOODING, PARTICULARLY IN SOUTHEAST UTAH AND SOUTHWEST
COLORADO. THE INCREASED MOISTURE AND PRECIPITATION KEEPS CRITICAL
FIRE WEATHER CONDITIONS OUT OF THE FORECAST.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
