The University of Michigan in Flint has announced it will close this evening and all day tomorrow. From their press release:
The University of Michigan-Flint campus will close today, Tuesday, February 1, 2011 at 4:00 PM in preparation for an approaching massive winter storm, and will remain closed for clean-up on Wednesday, February 2, 2011. All late afternoon and evening classes, activities, and events are canceled after 4pm today and through tomorrow. Critical personnel will report to work at their regularly scheduled shift time.
More than likely, there will be many more closings announced. WDIV's website has a pretty good roundup of announced closings. They say six closings have been announced so far.
