St. Lawrence County, NY – Drivers across parts of northern New York should prepare for hazardous winter travel starting Monday afternoon, as lake-effect snow moves into the region and continues into Tuesday.

According to the National Weather Service in Burlington, Vermont, a Winter Weather Advisory is in effect for southern St. Lawrence County, where a persistent band of lake-effect snow is expected to produce 3 to 6 inches of accumulation. Snowfall rates could become heavy at times, significantly reducing visibility and making road conditions dangerous.

Forecasters say the snow is expected to develop late Monday afternoon and continue through Tuesday, with the most intense snowfall likely in localized bands. Visibility could drop to one-half mile or less during heavier bursts, increasing the risk of accidents, especially on untreated roads.

Elsewhere across northern New York, snowfall totals are expected to remain lighter, generally 2 inches or less, though brief slick conditions are still possible during the evening and overnight hours.

The advisory highlights southern St. Lawrence County as having the highest potential for moderate to heavy snow, particularly in areas more exposed to lake-effect bands. Motorists are urged to allow extra travel time, slow down, and be prepared for rapidly changing conditions.

Residents are encouraged to monitor updated forecasts and check county-specific snowfall graphics through the National Weather Service as conditions evolve. Additional advisories or extensions are possible if lake-effect bands persist longer than expected.
