A tornado tore through Ann Arbor in the pre-dawn hours of April 15, its violent winds collapsing the wall of a local ice rink and snapping mature oak trees in Veterans Memorial park. The facility served 60,000 people annually through hockey leagues and recreational programs. It will not reopen this winter, if at all.
The April tornado was one of two devastating outbreaks that hit Michigan this year. In March, storms swept through nine counties and killed four people, including a 12-year-old child. That March event marked the earliest EF-3 tornado recorded in Michigan's documented history.
Michigan recorded 33 tornadoes last year, more than double its historical average of 15 annually. This year has already seen 15. The tornadoes followed severe flooding that threatened dams and levees across the state, forcing evacuations in northern communities like Cheboygan and triggering Federal Emergency Management Agency deployments across 30 counties.
The state's recent weather disasters carry particular weight because Michigan has long been viewed as relatively insulated from climate catastrophe. Florida, California, and the mountain west dominate discussions about climate vulnerability. Yet the Great Lakes region, sometimes called "climate proof," is now experiencing extreme events that rival any other part of the country.
The economic toll is mounting. Spring flooding threatens the outdoor recreation season, a vital driver for thousands of small businesses across 22 counties facing extensive cleanup. Campgrounds, trails, and equestrian facilities all scramble to repair damage before tourists arrive.
The state's recent trauma echoes an older one still raw. Six years ago, the Edenville and Sanford dams failed after 8 inches of rainfall, collapsing 100 miles northeast of Grand Rapids. The catastrophe forced 10,000 people to evacuate, damaged or destroyed 2,500 homes and businesses, and cost an estimated $175 million. Rebuilding those dams plus three others that failed will cost nearly $400 million.
Lynn Coleman, who runs Wixom Waters campground near the Edenville site, documented the lake draining in just over an hour and a half. The collapse devastated his water-based business, which has lost an average of $35,000 annually. Now he faces $30,000 yearly in lake assessment fees for the next four decades.
Residents pursued a lawsuit against Michigan, claiming the state failed to act on safety warnings about the dam despite allowing its operator, Boyce Hydro Power, to raise water levels. That lawsuit was dismissed last month.
Scientists point to a specific mechanism driving Michigan's volatile spring weather. The state often sits at the boundary where the jet stream transitions between warm, moist southern air and cold, dry Canadian air. This spring that boundary has been unusually active. Lisa DeChano-Cook, a professor at Western Michigan University's school of environment, geography and sustainability, explains the danger: "When you have warm, moist air that clashes with dry air, you get a very sharp boundary in temperatures that will cause severe weather."
The Great Lakes water temperatures also play a role. A strong contrast between cold lake water and warm, moisture-laden air from the Gulf can intensify precipitation and trigger more extreme outcomes, researchers say. Last year, a freezing rain storm destroyed millions of acres of trees in northern Michigan's lower peninsula, knocking out power for weeks and costing hundreds of millions of dollars in repairs and recovery.
Not all residents are convinced climate change bears sole responsibility. Coleman, drawing on decades of living near severe weather, said he has witnessed dangerous storms throughout his life and hesitates to assign blame without scientific expertise. Yet the data suggests a troubling shift. The National Centers for Environmental Information, a government agency, found that billion-dollar disaster events in the US adjusted for inflation jumped from 33 in the 1980s to 198 in the decade through 2024.
DeChano-Cook notes that warmer Arctic temperatures weaken the polar jet stream, causing it to bend more dramatically north and south. For the Great Lakes region and southern Canada, this waviness increasingly translates into extreme weather across larger areas.
Back in Ann Arbor, the city faces a summer dilemma. With a public pool next to the damaged ice rink, authorities delayed construction work to open the pool before the season. Losing one of just two city ice rinks cuts recreational capacity in half. Scott Spooner, an Ann Arbor parks manager, put the impact plainly: "There's a revenue hit and a social hit."
Author James Rodriguez: "Michigan's weather is no longer playing by the old rules, and the state appears unprepared for what comes next."
