Greasy Snow Triggers Hazardous Travel Alert
21 Mar
Summary
- Heavy, wet snow rates of up to 2 inches per hour created hazardous travel.
- Dense, moisture-laden flakes caused sharply reduced visibility and slick roads.
- Up to 4 inches of additional wet snow could fall, worsening travel conditions.
Northern New York and Vermont were struck by a significant snowfall on Friday afternoon, leading to hazardous travel conditions and multiple accidents. The National Weather Service issued a Winter Weather Advisory as snowfall rates climbed to an intense 1 to 2 inches per hour.
This "greasy" snow, characterized by its dense, moisture-laden flakes, quickly accumulated on roadways, causing sharply reduced visibility across the Champlain Valley. Drivers encountered slick, snow-covered roads, prompting meteorologists to advise delaying travel if possible. The wet snow's heavy nature also presents a physical challenge for shoveling, with potential health risks associated with overexertion.
Meteorologists noted that snowfall rates of this intensity can challenge snowplow operations, as roads can become re-covered rapidly. This rapid accumulation reduces traction and complicates the effectiveness of salt and sand treatments. The Winter Weather Advisory was set to remain active until 11 p.m. local time, with the potential for up to 4 additional inches of snow. Conditions were expected to improve after the heaviest bands moved out of the area, but hazardous travel was anticipated through the evening commute.
