Watertown, New York — Drivers across northern New York are facing hazardous travel conditions as persistent lake-effect snow continues to impact the Eastern Lake Ontario region, bringing heavy accumulations, blowing snow, and sharply reduced visibility through early Tuesday.
According to forecasters, a Winter Weather Advisory remains in effect for Oswego, Jefferson, and Lewis counties until 7 a.m. Tuesday. The most intense snowfall is expected across the Tug Hill Plateau, where an additional 5 to 10 inches of snow could accumulate before the advisory expires. In surrounding lower-elevation areas, including Watertown and Oswego, snowfall totals are expected to range between 2 and 4 inches.
Meteorologists say lake-effect snow bands will remain active through Monday, with periods of rapid intensity changes. Gusty winds between 35 and 40 mph are forecast to accompany the snow, leading to blowing and drifting snow that can significantly reduce visibility, especially in open and rural areas.
Travel conditions are expected to be particularly difficult along north–south roadways, including Routes 12 and 177, where shifting snow bands may quickly turn clear stretches of road into whiteout conditions. Officials warn that visibility may drop suddenly with little notice as snow bands move across the region.
Local highway departments have been treating and plowing roads, but the combination of persistent snowfall and strong winds may limit how quickly conditions improve. Drivers are urged to use caution, especially during the Monday evening and early Tuesday morning commute periods.
Emergency management officials recommend motorists slow down, increase following distance, and allow extra travel time. Drivers are also encouraged to carry winter emergency supplies, including blankets, food, water, a flashlight, and a fully charged phone, in case travel is delayed or vehicles become stuck.
The lake-effect snow is expected to gradually weaken late Monday night into early Tuesday as winds shift and colder air moves out of the region. However, slick and snow-covered roads may linger into Tuesday morning, particularly in areas that receive heavier snowfall.
Residents are advised to continue monitoring local forecasts and weather alerts, as snowfall amounts can vary significantly over short distances during lake-effect events.
