The National Weather Service in Flagstaff has issued a Red Flag Warning for western Yavapai and Coconino Counties until 6-pm tonight. This is due to strong winds and low relative humidity. This includes Prescott, Prescott Valley, Seligman and portions of the Coconino, Kaibab and Prescott National Forests. Officials say southwest wind gusts up to 35-mph are in the forecast. Any fires that develop will spread rapidly.
