    Chesapeake Bay Climate Impacts Summary and Outlook: Winter 2018-2019

    From December 2018 through February 2019, extreme weather events caused disruptions, delays, and damages within the Chesapeake Bay Watershed. A December snowstorm dropped up to 15.2 inches of snow on western and central Virginia, while a January storm caused more than 250 flight cancellations at Washington D.C.'s three main airports. In late January, a polar vortex resulted in cold, windy weather across the Mid-Atlantic region.
