With extreme fire risk conditions across much of Minnesota today (Thursday, May 6), the National Weather Service has issued a Red Flag Warning across several counties. A Red Flag Warning means the area is experiencing critical weather conditions that are ideal for wildfire, including strong winds and low humidity. Do not burn while the Red Flag Warning remains in effect and check any burning done recently to ensure the fire is out. Any spark could become a wildfire under Red Flag conditions. The Red Flag Warning expires at 8 p.m.
