Description: 
...PROLONGED CRITICAL FIRE WEATHER CONDITIONS EXPECTED FOR THE HIGH COUNTRY... A warm and dry airmass will coincide with considerably stronger west and southwest winds this weekend, potentially continuing into early next week. Sustained winds are expected to exceed 20 to 30 mph across much of the high country beginning Saturday, with gusts of 40 to 50 mph, strongest for exposed areas and higher elevations. These conditions will drive very high fire danger across the warned area, that may extend through the evening hours of Saturday driven by the enhanced winds. Any new starts or established fires will likely spread rapidly under these conditions. The National Weather Service in Denver has issued a Fire Weather Watch for wind and low relative humidity, which is in effect from Sunday morning through Sunday evening. * AFFECTED AREA...Fire Weather Zones 211, 212, 213, 214 and 218. * TIMING...For the Red Flag Warning, from 11 AM Saturday to midnight MDT Saturday night. For the Fire Weather Watch, from Sunday morning through Sunday evening. * WINDS...Southwest 20 to 30 mph with gusts 40 to 50 mph. * RELATIVE HUMIDITY...11 to 15 percent. * IMPACTS...Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.
