Scattered thunderstorms are expected across much of Michigan Monday evening and overnight. A couple of the thunderstorms could be relatively strong, with isolated large hail or damaging winds. There will also be an increasing flood threat as multiple chances for thunderstorms occur during the week.
Another round of potentially severe storms is expected late Tuesday as scattered thunderstorms move through the area. Damaging winds, large hail, and tornadoes will all be possible along with the continued flooding risk.
A flood watch has been issued for Mason, Lake, Osceola, Clare, Oceana, Newaygo, and Mecosta counties due to rainfall expected over the next several days. Go to weather.gov/grandrapids for more information.
