What is a Nor'easter?
|
|
| A "nor'easter" is an intense low pressure area that forms in the winter along the
east coast of the Unites States, producing strong northeasterly winds
and sometimes heavy snowfall
and rainfall. This is a favored region for winter storm formation, where the warm ocean water
and airmass along the coast meets cold air pouring down out of Canada. If an upper air disturbance
approaches the area from the west during these conditions, this especially intense form of a
extratropical cyclone can be expected to develop.
These storms often travel up along the coast, eventually affecting the entire eastern seaboard.
Persistent strong winds with these storms can cause beach erosion and damage to houses along the
coast from large waves and high water levels that result from the ocean water being piled up
against the coast by the wind. The nor'easter is usually followed by unusually cold weather
as the cold high pressure area that helped create the strong winds moves into the region.

| THE PERFECT STORM The movie "Perfect Storm" was based upon
the true story of a swordfishing boat, the Andrea Gail, that was caught in an intense nor'easter
in October 1991.
