Grand Rapids, Michigan – Damaging winds are the main concern across much of Michigan Saturday afternoon into Sunday morning as strong thunderstorms sweep from the lakeshore toward I‑75. Power outages, downed limbs, and brief flooding are possible, especially where storms train over the same areas during the evening commute and overnight.
According to the National Weather Service in Grand Rapids, a “marginal risk” for severe weather covers Western and Central Michigan Saturday, with the highest threat window from mid‑afternoon through late evening. The primary hazard is damaging straight‑line winds; large hail and a brief tornado can’t be ruled out. Locally heavy rainfall may lead to ponding on roads.
Statewide impacts include gusty storms along US‑31 and I‑96 from Muskegon and Holland east toward Grand Rapids and Lansing, spreading south on US‑131 toward Kalamazoo and north toward Big Rapids and Cadillac. In the city of Grand Rapids, outdoor events late day face lightning delays. Secure tents and patio furniture, charge phones, and avoid parking under trees. Drivers should slow down in downpours and never cross flooded lanes.
