BUFFALO, N.Y. (AP) – A dangerous lake-effect snowstorm paralyzed parts of western and northern New York, with more than a foot of snow already on the ground in places and a driving ban keeping people off the roads in the Buffalo area. The worst snowfall was expected in Buffalo, where the National Weather Service said up to 4 feet might fall in some spots through Sunday. Other areas could get a foot or less. New York Gov. Kathy Hochul declared a state of emergency Thursday for parts of western New York, including communities along the eastern ends of Lake Erie and Lake Ontario. Erie County Executive Mark Poloncarz issued a driving ban beginning Thursday night. Parts of Pennsylvania also were seeing accumulations of lake-effect snow.
