A cold front, supported by an energetic upper level system, moved across the Mississippi and Ohio River valleys to the eastern seaboard by midday Sunday (10/29) and initially developed an area of low pressure. Meanwhile, energy and deep tropical moisture, associated with the remnants of Tropical Storm Philippe (well offshore of the southeast United States) interacted with the developing east coast storm to create a rapidly intensifying storm Sunday night off the mid-Atlantic coast that traveled into the Champlain Valley by Monday morning (10/30).
Sustained winds of 25 to 35 mph with frequent wind gusts of 50 to 70 mph occurred during the early morning hours of October 30th across portions of Vermont due to fully mature mountain waves. A peak wind gust of 115 mph was observed at the summit of Mount Mansfield.
Numerous downed branches, trees and some snapped and uprooted trees causing widespread power outages, especially in VT where 30% of the power grid or >100,000 customers were without power. Trees fell on residences and vehicles as well. The hardest hit communities were along the western slopes of the Green Mountains.
