Special Weather Statement issued June 4 at 10:48AM CDT by NWS Duluth MN
Effective: Wed June 4, 2025, 10:48 AM
Expires: Wed June 4, 2025, 6:00 PM
Dry conditions and breezy west winds will lead to near-critical fire weather conditions for the Minnesota Arrowhead region today. West winds of 5 to 10 mph with gusts of 15 to 20 mph are forecast. Minimum relative humidity values of 20 to 30 percent are also expected, with some locations that have not experienced recent rainfall possibly seeing relative humidity values less than 20 percent. Together, these conditions could lead to the rapid spread of fires. Check burning restrictions and fire danger before burning.
