Winter weather advisory

Winter weather advisory,
A Winter Weather Advisory is issued by the National Weather Service of the United States when a low pressure system produces a combination of winter weather (snow, freezing rain, or sleet) that presents a hazard, but does not meet warning criteria. A Winter Weather Advisory is similar to significant weather alert, though a winter weather advisory is an official product. A "Winter Weather Advisory" means that a period of winter weather will make traveling difficult.
A similar warning is issued by Environment Canada's Meteorological Service of Canada offices.
