RISKS
A polar vortex is blasting the U.S. Midwest and Northeast this week, subjecting millions of Americans to dangerous subzero temperatures. The extreme cold is expected to smash dozens of records in the Midwest and Great Lakes region. Temperatures there will drop to 20-40 degrees below zero, with winds chills of 35-60 below. Heavy snow, including blizzard conditions in the Dakotas, will make traveling “dangerous to impossible” throughout the area, reports the National Weather Service. The snow will even reach as far south as Mississippi, Georgia and Alabama — just in time for Sunday’s Super Bowl in Atlanta. If you’re lucky enough to be able to stay put, you can watch this winter show from the comfort of your warm house or apartment. But the moment you venture outside, this kind of extreme weather can put your health at risk in a number of ways.
