A classic Nor'easter is set to cripple major cities in America's northeast with one to two feet of snow and gale force winds. This storm is expected to be the strongest of its kind in at least a decade. Blizzards are expected to lash the northeast of the United States of America with New York expecting a foot of snow in 24 hours. Boston will be hit even harder with two feet of snow expected. This is only a foot short of the record snow fall in Boston of 37 inches. A classic Nor'easter is named after the very strong northeasterly winds. It occurs when a low pressure system moves north up the east coast of the United Sates, drawing warm water from the Gulf Stream at the same time as pulling cold air south from Canada. The combination of very moist and cold air leads to the heavy snow amounts. Blinding snow will combine with the very strong winds to produce blizzard conditions. Many schools have already been closed and roads will become impassible until they are cleared over the coming days.
