The National Weather Service has issued a Red Flag Warning for Tuesday, Sept. 19 that includes Coal Creek Canyon. A Red Flag warning means weather conditions (typically a combination of winds, heat, and low humidity) are set for potential extreme fire behavior; i.e. significant combustion and rapid spread.
A red flag warning allows NO open air burning. The forecast is for increased fire danger through Thursday, so fire restrictions are likely to extend through most of this week.
