Roughly 500,000 people in New York and Ohio are bracing for dangerous travel conditions as multiple lake-effect snow warnings remain in effect Tuesday, with some areas expected to receive up to 10 inches of snow, accompanied by strong winds and low visibility from blowing snow.

Why it matters

Lake effect snow is a common occurrence across the Great Lakes region, arriving when cold air, typically from Canada, moves across the warm waters of the lakes, causing the air to rise and form clouds that can unleash several inches of snow per hour. This can create fast-changing visibility and road conditions, posing a serious threat to motorists.

The details

The new batch of winter weather-related warnings comes only a day after winter weather advisories, severe thunderstorm warnings, and tornado warnings swept across the East Coast. Forecasters say narrow but intense snow bands will set up across several counties downwind of Lake Ontario and Lake Erie, producing snowfall rates that can shift from near-zero to blinding within minutes. Gusty winds of up to 45 mph in some regions will also produce blowing and drifting snow, heightening travel risks.

  • The lake-effect snow warnings remain in effect through Tuesday night or early Wednesday, depending on location.
  • The heaviest snowfall is forecast across the central portions of Oneida County in New York on Tuesday evening and Wednesday morning.
  • In Ohio, the lake effect snow warning remains in effect until 5 p.m. Tuesday for Geauga County.
