00:00A large and an intense storm that not only produces damage, but can shut down travel

00:06and alter daily life along the eastern seaboard. We're talking about the nor'easter. It gets its

00:14name from the northeasterly wind it produces. It can occur from September through April,

00:21but late January through March is nor'easter season, and there's a reason for that.

00:26These storms feed on temperature differences, right? You get arctic air coming across the

00:33Midwest and the Northeast. Meanwhile, you have the warm Gulf Stream off the eastern seaboard. That

00:38creates a large temperature differences where storms can generate more energy, and then when

00:44you bring the jet stream southward, it forms the storm, and if the jet stream is configured correctly,

00:50that storm comes up the eastern seaboard. Of course, nor'easters are known for the strong

00:56winds and the heavy snow, but they also produce heavy amounts of rain, and they can produce

01:03coastal damage not only from wind, but strong waves that get pushed toward the shore. They

01:11also can produce severe weather along the Gulf Coast and Florida, so they have lots of impacts.

01:18The most historic nor'easter that I've seen in my 35-year career at AccuWeather was the blizzard
