Red Flag Warning Issued as Thumb Fire Expands in St. Louis County, MN
A dangerous wildfire situation continues across St. Louis County, Minnesota, as the Thumb Fire has grown to approximately 12,327 acres amid ongoing extreme fire weather conditions. A Red Flag Warning remains in effect as dry fuels, gusty winds, and low humidity create conditions where fires can spread quickly and become difficult to control.
Fire officials are urging residents and visitors across northern Minnesota to use extreme caution as any spark could ignite rapidly moving flames. Red Flag Warning conditions mean wildfires have the potential to grow quickly due to the combination of dry vegetation, strong winds, and low relative humidity.
Thumb Fire Conditions and Growth
