A significant winter storm will affect Philadelphia and the surrounding areas Monday morning, and a state of emergency is currently in effect across South Jersey.

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, Baltimore and Philadelphia, are now experiencing significant impacts from heavy snow and ice.

Philadelphia's highly-anticipated first measurable snowfall this winter is inching closer and closer, with the first flakes expected overnight.
