Special Weather Statement issued February 25 at 4:43AM EST by NWS Gaylord MI

Effective: Wed February 25, 2026, 9:43 AM
Expires: Wed February 25, 2026, 3:00 PM

Commutes this morning will be impacted by lake effect snow showers across much of northern lower and eastern upper Michigan. Reduced visibility (at times below one mile) from falling and blowing snow is likely along with snow-covered roads... both from snow yesterday evening and snow actively falling. Be sure to give yourself some extra time for the morning commute, and increase your following distance between yourself and the vehicle in front of you. When encountering reduced visibility, be sure to utilize low-beam headlights in order to make yourself more visible to other motorists.

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.
