Fire officials warn Northland residents to avoid wildfire sparks this weekend

Dry grass, open burning and a stray spark can turn dangerous fast in the Northland, and fire officials are warning residents to treat Memorial Day weekend as a high-risk stretch rather than a routine holiday. The Minnesota Department of Natural Resources says spring burning restrictions remain in place for most Minnesota counties, including St. Louis County, and only certain permits are allowed as dry conditions persist.

The risk is not theoretical. The DNR says grasses and leaves can dry in as little as one hour after precipitation ends, while small branches and twigs can be ready to burn in about 10 hours. Campfires should stay smaller than 3 feet by 3 feet, and the agency says fires must be fully extinguished with its drown-stir-repeat method. The DNR also says escaped debris fires are the No. 1 cause of wildfires in Minnesota, a warning that lands at a time when more people are burning outdoors, using equipment in yards, and traveling through dry roadside grass.

St. Louis County is already under expanded spring burning restrictions after the DNR added the county on April 20. In the April 19 order, the agency said it would not issue permits for open burning of brush or yard waste in restricted counties until the restrictions are lifted. The state says its fire danger and burning-restrictions maps are updated daily and refresh automatically every five minutes, with ratings that range from low to extreme.

The concern is sharpened by what happened just north of the county. The Stewart Trail wildfire in Lake County burned about 356 acres and destroyed 34 structures, including eight primary buildings and 26 outbuildings, before crews reported it 100% contained and lifted evacuation zones on May 20. During that response, Gov. Tim Walz declared a peacetime emergency and activated the Minnesota National Guard, underscoring how quickly a local fire can demand state-level resources.

St. Louis County’s own wildfire planning shows why officials are pressing the issue now. The county’s Community Wildfire Protection Plan identifies wildland-urban interface areas where trees, brush and other vegetation threaten homes and structures. County firewise materials also say permits help emergency managers provide a rapid and efficient response if a fire becomes uncontained. With more than 90% of Minnesota wildfires caused by people, the biggest threat this weekend is not lightning or some distant disaster. It is a careless burn pile, a chain dragging behind a trailer, a mower blade hitting dry grass, or an ash disposal mistake that sends crews racing to another fire.
