(Bloomberg) --

A cold air front crossing Lakes Erie and Ontario could drop 12 to 18 inches (30.5 to 45.7 cm) of snow across western New York, including towns south of Buffalo this week.

The area likely affected includes a large stretch of Interstate 90 — a vital east-west highway across the US — that could get as much as a foot in areas where it skirts Lake Ontario.

New York Governor Kathy Hochul urged travelers to take precautions and said she would be monitoring the situation, in a post on X, formerly known as Twitter.

Meanwhile on the eastern shore of Lake Ontario, Pulaski, New York could get up to 24 inches (61 cm). Interstate 81, a north-south artery into Canada runs through this region.
