A significant winter storm has blanketed parts of New York and Pennsylvania with up to three feet of snow, prompting emergency declarations in both states. Travel conditions are treacherous, with authorities reporting nearly 200 incidents involving stranded motorists. With additional snowfall expected, officials urge people to avoid travel unless necessary. Emergency services and the National Guard are deployed to assist, particularly in affected areas near Lakes Erie and Ontario. Residents are advised to shelter in place as conditions are likely to worsen, especially during this busy holiday travel period.
