In January of 2019, a record-breaking winter storm tore through the Midwest inflicting major damages and taking twenty-one lives. The U.S. Postal Service suspended service in parts of several states.

Depending on which way it’s tilted changes where the cold air is going to go. Discussing the measures taken during and after the winter storm to prepare and assist the community in insuring the safest outcome, Paul Gross, meteorologist at WDIV in Detroit, Michigan, states, “I always give the public very specific communication regarding timing and impacts of the approaching weather… during the storm, I step up my social media reporting, frequently tweeting radar images, temperatures, etc. After a winter storm, I communicate ‘what to do’ information, such as if somebody sees a downed power line, if their gutters are overflowing with ice and icicles, etc.” Scientist are not sure why the vortex is moving south toward the U.S. however, they have discovered that it is going to become common.
