A new polar vortex is bearing down on Michigan and the upper Midwest, forcing widespread school closures, forcing Wayne State University and Michigan State University to cancel classes and the Detroit Zoo to close. On today’s episode, we run down some of the knock-on effects of the dangerously cold weather, which is expected to produce subzero temperatures and dangerously cold wind chills. Jer speaks with Gary Brown, director of the Detroit Water and Sewerage Department, about the risks to the city’s aging infrastructure.
