A snow squall is a sudden heavy snowfall that consists of strong and gusty surface winds, it’s similar to a blizzard but is more localized.

“Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common,” reads the alert. “Visibility may be suddenly reduced at times in heavy snow.”
