The National Weather Service has issued a series of Winter Storm Warnings, with some areas expected to receive up to a foot of snow early this week.
What are snow flurries?
A blizzard is a long-lasting snowfall that results in significant snow accumulation. On the other hand, snow flurries are short-lived and occur when snow falls in strong wind conditions, creating thin layers of instant freezing.
Snow flurries come in two types: frontal effect and lake-effect. Frontal flurries occur along, in front of, or behind an Arctic front, producing narrow bands of intense snowfall for short periods of time. Lake-effect snow flurries, on the other hand, occur near large bodies of water and can last for hours.
Why are snow flurries so dangerous?
Unlike winter storms, snow flurries can quickly create a slippery layer of ice on roads due to strong wind conditions, threatening drivers. The National Snow and Ice Data Center defines a snow squall as “a brief but intense snowfall that greatly reduces visibility.”
Rather than the temperature, it is the danger these storms create for drivers that make them such a threat.
