Tornado warning issued for northwestern Menominee County as severe storms sweep Wisconsin

A tornado warning covered northwestern Menominee County and southeastern Langlade County on April 17, expiring at 6:15 p.m. CDT. Emergency alerts urged preparedness, and the notices did not mention sirens, school closures, road shutdowns or tribal facility actions in the warning zone.

The local warning landed during a fast-moving outbreak that the National Weather Service said began around 1 p.m., when thunderstorms developed along a cold front in southeast Minnesota and a warm front in western Wisconsin. Supercell storms then tracked east through the afternoon and exited central Wisconsin after 6:30 p.m., according to the National Weather Service La Crosse office.

That office said it issued 26 tornado warnings that day, the most in a single day since it was built in 1995. It called the system the largest April tornado outbreak on record for the office, with preliminary reports of more than 100 homes damaged across the Upper Midwest. In Wisconsin, where tornadoes are uncommon but not rare, the state averages about 23 tornadoes a year, and the Wisconsin Department of Health Services says the National Weather Service typically issues one to two tornado warnings per county per year in southern Wisconsin counties.

A separate National Weather Service Green Bay warning at 6:06 p.m. showed how quickly the threat was moving north. Radar showed a severe thunderstorm capable of producing a tornado near White Lake, moving northeast at 30 mph. The alert warned of flying debris, possible destruction of mobile homes, roof and window damage, and tree damage. It said White Lake and Gardner Dam Scout Camp could be impacted around 6:10 p.m., and also named Langlade, Hollister, Boot Lake Campground, Townsend and Lakewood.

The warnings came during Severe Weather Awareness Week, when Wisconsin Emergency Management and the National Weather Service were pushing tornado drills and preparedness messaging across Wisconsin and Minnesota. For Menominee County residents, the lesson is simple: a warning means immediate action, especially when radar shows rotation and nearby places such as White Lake or Gardner Dam Scout Camp are named in the path. The next alert may arrive with little time to spare, and those first minutes are the difference between shelter and exposure.
