Heavy snow was coating part Northern and Western New York early Tuesday as a lake-effect snowstorm continued to wallop the region, causing hazardous travel conditions, forecasters said.
The storm was holding steady, with snowfall rates over one inch per hour, which, combined with winds of about 35 miles per hour, could produce blowing and drifting snow, meteorologists said.
Travel across the region on Tuesday would be difficult, with poor visibility. Heavy snow was expected to cover roads, creating treacherous conditions for the morning and evening commutes. As of early Tuesday, more than 3 million people from the far eastern tip of Ohio through parts of northern and western New York were under a lake effect snow warning.
On Monday, the heaviest snow was falling just south of Buffalo, said Joe Wegman, a meteorologist with the Weather Prediction Center of the National Weather Service. The storm was expected to continue through early Wednesday morning. People in the region should avoid “all travel,” he said, to allow “the plows to get out and do their jobs.”
Videos posted to social media appeared to show extremely poor visibility and traffic at a standstill in the Buffalo region. The New York State Thruway Authority was reporting crashes, disabled vehicles and delays on the Interstate 90, which runs east to west across the state. The AAA said on X that service may be slowed because of the heavy snow and slick roads.
The worst conditions were expected on Tuesday with the heaviest snow falling through the afternoon.
“The greatest accumulations will remain south of Watertown and across the Tug Hill Plateau,” which is east of Lake Ontario, forecasters said. “Areas outside of the lake effect will largely see nothing more than a passing snow shower at times.”
The National Weather Service said a lake-effect snow warning would be in effect for Jefferson, Lewis and Oswego Counties until 7 a.m. Wednesday.
A warning was in effect for northern Oneida and Onondaga Counties, including Syracuse, through 7 a.m. Wednesday, with accumulations up to 14 inches.
Lake-effect snowstorms come when the Great Lakes are warm and have not yet frozen over for the season, and a strong wind blows across them. Narrow bands of snow can then quickly pile up, making travel especially treacherous, even in a region where residents are accustomed to severe winter weather.
On Monday morning, shoppers were flocking to the Lowville Farmers Co-Op in Lowville, N.Y., about an hour north of Rome, N.Y., in preparation for the storm, said the store’s comptroller, Jennifer Garcia.
She said residents pay closer attention when the forecast calls for lake-effect snow because it is hard to predict where it will be most intense.
She recalled that during one such event last year, workers coming from within a few miles of the store found themselves either smothered with snow or having none at all, depending entirely on which direction they were coming from.
“You just don’t know how those bands will set,” she said.
