Not Unstoppable: Sandy Tapering off in Appalachia It felt like Superstorm Sandy would never go away. But its days are numbered. The storm is winding down days after it swamped the East Coast, buried states in snow and killed dozens of people. The National Weather Service said Wednesday that the last effects of the remnant low that was Sandy are being felt in the Appalachian mountains. The storm brought up to 3 feet of snow to parts of West Virginia and Maryland and put thousands in the dark. The Weather Service says several more inches are possible before the storm dies out for good later this week.
