What do these weather alerts mean

A winter storm warning is issued when a storm is expected to produce heavy snow or heavy ice accumulations. The exact criteria vary by region of New Jersey and eastern Pennsylvania.

During a 12-hour storm, like this one, storm warnings are triggered when the snow forecast begins at 5 inches across southern Jersey, along the eastern Jersey coast and across the Philadelphia metro area. In the northern half of the Garden State, a snow forecast of 6 inches or more will trigger a winter storm warning.

A winter weather advisory is issued when a storm is expected to produce a combination of winter conditions – such as snow, sleet, freezing rain, or mixed precipitation – that present a hazard but do not meet the warning criteria. The National Weather Service typically issues an advisory if 2 inches or more of snow is forecast in southern Jersey and 3 inches of snow in northern Jersey.
