Special Weather Statement issued May 9 at 6:25AM CDT by NWS Twin Cities/Chanhassen MN

Effective: Sat May 9, 2026, 6:25 AM
Expires: Sat May 9, 2026, 7:00 PM

Another elevated fire weather day is expected across the area that has yet to fully begin their growing season from western to central Minnesota. Winds are expected to increase during the daylight hours, with sustained winds increasing to 15-20mph with gusts as high as 30mph out of the northwest. As winds increase, temperatures will warm into the low 60s, allowing relative humidity to fall into the low to mid 20 percent range this afternoon. The combination of the relative humidity and winds will lead to the elevated conditions, however peak wind gust strength should stay below Red Flag criteria. Check burning restrictions and fire danger levels and consult with fire officials before burning. For more information on burning restrictions for Minnesota, see www.dnr.state.mn.us/forestry/fire/firerating_restrictions.html.

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.
