Mount Washington is the highest peak in the Northeastern United States at 6,288 ft (1,917 m). It is famous for its dangerously erratic weather, and long held the record for the highest wind gust directly measured at the Earth's surface.
The weather of Mount Washington is notoriously erratic. This is partly due to the convergence of several storm tracks, mainly from the South Atlantic, Gulf region and Pacific Northwest. The vertical rise of the Presidential Range, combined with its north-south orientation, makes it a significant barrier to westerly winds. Low-pressure systems are more favorable to develop along the coastline in the winter months due to the relative temperature differences between the Northeast and the Atlantic Ocean. With these factors combined, winds exceeding hurricane force occur an average of 110 days per year. From November to April, these strong winds are likely to occur during two-thirds of the days.
