Detroit, Michigan – Drivers across Michigan could face slick highways and reduced visibility by Wednesday morning as repeated rounds of rain begin impacting travel during peak commute hours statewide.
According to the National Weather Service Climate Prediction Center, Michigan is in a high-confidence zone for above-average precipitation from Wednesday through Saturday, with totals expected to run 30 to 60 percent higher than normal. Warmer air will also surge into the region, with a 70 to 80 percent probability of above-normal temperatures across the Midwest and Great Lakes.
Detroit, Lansing, and Grand Rapids are expected to see multiple waves of rainfall, increasing the risk of standing water on major corridors including I-94, I-75, and I-96. In western Michigan, including Grand Rapids and Muskegon, periods of heavier rain could reduce visibility below one mile at times. Mid-Michigan cities like Flint and Saginaw, along with Ann Arbor in the southeast, may see water collect quickly in low-lying and poor drainage areas.
Drivers should slow down on wet roads, avoid water-covered highways, and allow extra time for commutes. Residents are encouraged to clear storm drains and check sump pumps ahead of the heaviest rainfall.
This wet and warm pattern is expected to continue through Saturday night, with additional advisories likely as rainfall totals and timing become more defined.
