- Snow Squall Warning
A warning issued by Environment Canada’s Meteorological Service (MSC) for localized, limited duration, intense snowfall that reduces visibility significantly and may be accompanied by strong, gusty winds and (in some cases) lightning. These weather conditions are produced by the passage of cold air over an open body of water (open water squall) or the passage of a cold front (frontal snow squall). Local snow accumulations may be significant during this type of event.
