MAIN Science Meteorology Blizzards

What sets a blizzard apart from your everday garden variety snowstorm?

One major factor is wind, in excess of 35 mph. Another is time — strong gusts and snow that last for at least 3 hours will usually turn a winter storm into a cold weather 'event' worthy of special attention.

Some of the most memorable blizzards in the U.S. have occured on the East Coast, known as Nor'easters. They form when warm moist air moves north along the coast to clash with cold blasts from Eastern Canada.

Like those in 1888, 1947, 1969, 1978 and 1996 the most infamous Nor'easters have stalled over the coast, lasting anywhere from 12 to 24 hours with snow amounts measured in feet rather than inches. The result? Even residents in big cities quickly learn of nature's dangers when snarled traffic effects the movement of emergency vehicles and food deliveries, and accompanying gusts take down electric and telephone lines.

Blizzard safety tips to follow before and after a blizzard include stocking up on extra food and supplies, and having a cell phone and emergency numbers readily available. During the storm, stay indoors and off the road whenever possible. It's also wise to keep a blizzard emergency kit stored in the trunk of your car in the event of getting stuck on a highway during a major blizzard.
