Wider weather episode

Low pressure developed off the Carolina coast during the late afternoon/evening hours of March 13th and reached offshore of southeastern Massachusetts by the morning of March 14th and then slowly meandered in the Gulf of Maine until the morning of March 15th before exiting away from New England.

Snow began across portions of northern New York just after midnight on March 14th with snowfall rates increasing to more than an inch (up to 2 inches) per hour during the morning and afternoon hours before gradually diminishing but still accumulating until the early morning hours of March 15th. Brisk north winds gusting 35-45 mph during the night of March 14th, especially in the Champlain valley accounted for some traveling and power issues.

Snowfall totals ranged from 6 to 12 inches in the Champlain Valley and along the International border with Canada to 10 to 18 inches for much of the rest of Vermont with the south and central mountain communities receiving greater than 2 feet.

The wet nature of the snowfall led to scattered to numerous power outages with more than 10,000 customers without power in Essex county. In addition, dozens of roads were closed due to vehicle accidents and downed trees and utility lines as well as many schools closed.
