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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
