A powerful storm system well north of Colorado will increase west winds across the northern half of Colorado throughout the afternoon and evening hours. Red flag conditions are expected Friday afternoon for strong winds and low relative humidity. The strongest winds and driest conditions are expected east of the Divide across Larimer County, though favorable conditions for rapid fire growth are possible across all of the warned area.
