An intense band of lake-effect snow is producing snowfall of two to three inches per hour in southern Erie, Cattaraugus, Chautuauqa, Livingston and Wyoming counties, the National Weather Service reported Monday evening.
A lake-effect snow warning remains in effect until 6 p.m. Wednesday for southern Erie County and the Southern Tier.
The National Weather Service predicted heavy lake-effect snow, with total snow accumulation of 2 to 3 feet in areas of the most persistent lake snows. Winds gusting as high as 35 mph could cause areas of blowing and drifting snow and near whiteout conditions.
The snow band was expected to continue to hit hard through midnight the southern portions of Erie and Wyoming counties, as well as the western Southern Tier north of Interstate 86.
Updated 24-hour snowfall reports from spotters as of 8:25 p.m. Monday showed East Aurora had 9.6 inches of new snow, Silver Creek had 6.2, and Warsaw, in Wyoming County, had 12 inches.
Earlier, at 5:09 p.m., weather spotters recorded these totals: Chaffee, a hamlet in southeastern Erie County, with 14 inches; Chautauqua and Mayville, in Chautaqua County, with 11 inches.
Interstate 86 was closed from the Pennsylvania state line to Bemus Point in both directions because of bad weather conditions and car crashes, as snow-covered roads continue to create perilous conditions for drivers throughout the region. Authorities closed the highway, also known as the Southern Tier Expressway, at about 1:20 p.m. Monday, according to a Chautauqua County Sheriff's Office dispatcher.
A winter weather advisory remains in effect until 8 p.m. Monday for Niagara, Orleans, northern Erie (Buffalo and areas north) and Genesee counties with gusty winds causing areas of blowing and drifting snow. The Genesee County Sheriff's Office canceled a traveler's advisory at 10 a.m. Monday but warned roadways remain snow-covered.
The weather forecast for Buffalo on Tuesday is mostly sunny, with a high near 14, wind chill values as low as -5, with a west wind 15 to 20 mph. By Tuesday night, the forecast calls for a slight chance of snow showers before 8 p.m., with a low around 6 degrees. The chance of precipitation is 20%.
