A deadly winter storm is pummeling Washington, DC, and the mid-Atlantic Monday after causing hundreds of crashes and flight cancellations and knocking out power to hundreds of thousands in the central United States over the weekend.

A major winter storm caused dangerous travel conditions and delays across the central and eastern U.S., including Washington D.C., as snow piled up.

The first major winter storm of the year that stretched across the U.S. is continuing its deadly journey eastward, where cities in the mid-Atlantic, like Washington and Baltimore, experience significant impacts from heavy snow and ice.
