York, Pa. – Heavy snow is spreading across the Pennsylvania–Maryland border region tonight as the same powerful coastal storm intensifies to the east, bringing widespread winter storm warnings and hazardous travel conditions inland. While the strongest blizzard conditions remain closer to the coast, steady snowfall will impact communities from York and Hanover to Hagerstown and Cumberland through Monday.
According to NOAA and the National Weather Service, winter storm warnings cover much of south-central Pennsylvania and western Maryland, including York, Franklin and Washington counties. Snow will continue overnight and into Monday, reducing visibility and creating snow-covered roads across Chambersburg, Gettysburg and surrounding areas. The storm is part of a larger system producing extreme impacts along the Eastern Seaboard, but inland communities will still face significant disruptions.
Even without coastal wind intensity, the snow will be dense and at times moisture-laden, increasing its weight. That can make clearing driveways and sidewalks physically demanding. Health officials urge residents to take frequent breaks, avoid lifting heavy shovelfuls and push snow whenever possible. Overexertion during snow removal can trigger serious medical emergencies, particularly among older adults and those with heart or respiratory conditions. The weight of the snow may also stress tree limbs and power lines, leading to scattered outages across both states.
Travel is strongly discouraged except for emergencies. PennDOT and the Maryland Department of Transportation warn that Interstate 83, Interstate 81 and rural roadways may become slick and snow-packed during peak snowfall Monday. If stranded, drivers should remain inside their vehicle with a winter emergency kit rather than attempting to walk in hazardous conditions.
Snow will taper late Monday into Tuesday, though icy patches may linger. Additional advisories could follow as the storm pulls farther northeast.
