Near-critical fire weather today across St. Louis County, low humidity fuels risk
Low humidity dropped to 15% to 25% across the Iron Range and Arrowhead, with fires able to spread quickly this afternoon and evening. Debris burning should wait.
Residents across the Iron Range and Arrowhead should put off debris burning and any other open-burn plans today, as National Weather Service Duluth said relative humidity was dropping to around 15% to 25% and fires could spread easily this afternoon and evening. Warm, largely dry weather was in store, with only limited chances for rain or thunderstorms over the next few days.
The near-critical fire weather setup stretched across the Iron Range, the Arrowhead and areas north toward the Canadian border, with the Weather Service also flagging northeast Minnesota and northern Wisconsin. Forecasters tied the risk to dry fuels and said the office is updating its broader fire-weather outlook through its fire weather pages and dashboard. Better chances for showers and thunderstorms were not expected until Wednesday or Thursday.
For St. Louis County, the warning lands in a region that already lists wildfire as one of its top risks. County preparedness materials direct residents to Firewise guidance, emergency-management resources and a county evacuation map, underscoring how quickly a fire can force changes in travel, school, work and access to homes and cabins when the weather turns this dry.
The Minnesota Department of Natural Resources has said escaped debris fires are the number one cause of wildfires in Minnesota. The agency requires a burning permit for debris burning when conditions allow, and says an online permit costs $5 and is good for the calendar year. It also says residents should check burning restrictions and daily fire-danger ratings before lighting any fire, even for small amounts of dry leaves, brush, plant clippings or clean untreated wood.
The warning comes after a spring of tightening restrictions across Minnesota. The DNR issued a Red Flag Warning for 54 counties on May 15, expanded burning restrictions on April 20, and added more counties again in early May as warm, dry conditions spread. In St. Louis County and across the Arrowhead, the message today is simple: a routine burn can turn into a wildfire fast when humidity falls this low and the afternoon wind starts working on dry fuels.
