What is a snow squall?

The NWS says “Snow squalls, often associated with strong cold fronts, are a key wintertime weather hazard. They move in and out quickly, and typically last less than an hour. The sudden white-out conditions combined with falling temperatures produces icy roads in just a few minutes. Squalls can occur where there is no large-scale winter storm in progress and might only produce minor accumulations. Snow squalls can cause localized extreme impacts to the traveling public and to commerce for brief periods of time. Unfortunately, there is a long history of deadly traffic accidents associated with snow squalls. Although snow accumulations are typically an inch or less, the added combination of gusty winds, falling temperatures and quick reductions in visibility can cause extremely dangerous conditions for motorists.”

What to do during a snow squall?

The NWS recommends delaying your travel if you are not on the roads yet. If you are on the roads, slow down, turn on your headlights, and hazard lights. Keep a lot of distance between you and the vehicle ahead of you. Try not to slam on your breaks because roads may be slick as well. The NWS also says, “There is no safe place on the highway when snow squalls are approaching.”
