Grand Rapids, Michigan – Drivers across western Michigan could encounter sudden downpours and hail-covered roads before sunrise Tuesday as a line of storms pushes in overnight, reducing visibility and slowing early commute traffic.
According to the National Weather Service in Grand Rapids, showers and thunderstorms will develop after 11 p.m. Monday and continue through 8 a.m. Tuesday, with the strongest cells capable of producing large hail and heavy rainfall. The primary threat centers on hail, with a 20% to 40% probability in parts of the region, while damaging wind risk remains lower but still possible in isolated storms
The highest impacts are expected from Muskegon through Grand Rapids and south toward Kalamazoo, where bursts of rain could briefly flood low-lying roads and create ponding on major routes like US-131 and I-196. Elevated storms may limit tornado risk, but officials warn that hail could damage vehicles and make untreated roads slick during peak travel hours.
Residents are urged to park vehicles in covered areas, charge devices overnight, and allow extra travel time Tuesday morning. If thunder is heard, moving indoors remains the safest option.
Storm activity should taper off by mid-morning Tuesday, but additional advisories could be issued if stronger cells develop overnight.
