A red flag warning is in effect for nearly all of Minnesota on Tuesday, according to the National Weather Service (NWS). The agency said that a combination of strong winds, low humidity and warm temperatures will contribute to "extreme fire behavior.

A serious situation is unfolding in northern Minnesota, where multiple wildfires have sprung up during tinderbox-dry conditions, and an increasing number of residents are now subject to evacuation orders as the blaze consumes properties. Authorities in St. Louis County are responding to:

The smoke from the wildfires entered northwestern Minnesota early Friday morning and will continue to push south throughout the day, behind a cold front. It'll make its way to the Brainerd area by 1 p.m. and to the metro by 7 p.m., the agency says. By 1 a.m. Saturday, it will have moved south through Rochester, slowly dissipating along the way.
