Fire Weather Watch
2025-12-20T00:00:00-07:00

...CRITICAL FIRE WEATHER CONDITIONS THURSDAY AND FRIDAY... Strong northwest winds will spread across the northeast plains after sunrise today, with gusts 45 to 65 mph creating critical fire weather conditions despite somewhat marginal humidity values near 20%. Early Friday, westerly downslope winds will bring strong gusts to the Front Range mountains and foothills, with potential for these to spread into wind-favored portions of the adjacent lower elevations. Peak gusts of 70-90 mph are increasing in likelihood for the windiest locations (considerably lower for areas along and east of I-25). With a warmer and drier air mass in place, humidity values in the teens look to extend into much of the foothills, and certainly across the lower elevations. Such conditions may be a longer duration than usual, with potential for low humidity to extend into the evening hours prior to the arrival of a front. The National Weather Service in Denver has issued a Fire Weather Watch for wind and low relative humidity, which is in effect from Friday morning through Friday evening. * AFFECTED AREA...Fire Weather Zones 215, 216, 241, 243, 245, 246 and 247. * TIMING...From Friday morning through late Friday evening. * WINDS...West 25 to 35 mph with gusts up to 80 mph in and near the foothills. West 15 to 25 mph with gusts up to 45 mph for areas roughly along and east of I-25. * RELATIVE HUMIDITY...As low as 10 to 15%. * IMPACTS...Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.
