...THIS IS A PARTICULARLY DANGEROUS SITUATION FOR IN AND IMMEDIATELY ADJACENT TO THE FOOTHILLS, BETWEEN 5500 AND 9000 FEET, FOR BOULDER AND JEFFERSON COUNTIES ON FRIDAY... Strong west winds of 30-40 mph with gusts as high as 85 mph in the foothills of Boulder and northern Jefferson Counties will continue until early evening. Relative humidity values had dropped into the upper single digits and lower teens. Thus, the Particularly Dangerous Situation will remain in place til around 5-6 pm, with only a slow improvement thereafter as winds slowly weaken. Red Flag conditions, however, will persist through the rest of the evening as we remain in a near record warm, dry, and windy airmass along the Front Range through midnight. In fact, strong, gusty winds will persist through much of the night with only a slow improvement in humidity values. Thus, near critical Red Flag conditions will occur into early Saturday morning. While most of the Denver metro area has seen lighter winds prevail most of the day, a period of strong, gusty winds is expected to develop this evening and likely last past midnight, producing Red Flag conditions there. * AFFECTED AREA...Fire Weather Zones 238, 240, 241, 242 and 243. * TIMING...Until midnight MST tonight. * WINDS...West 15 to 25 mph with gusts up to 50 mph. * RELATIVE HUMIDITY...As low as 9 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.
