At 400 PM EDT...National Weather Service radar and surface
observations showed a strong cyclone impacting the Northeast this
afternoon with periods of rain and blustery winds. The storm's
baromtetric pressure was noted at 979 mb, or 28.91 inches of
mercury, and located south of Mount Washington, New Hampshire.
Last night and earlier this morning, the storm's impressively low
barometric pressure broke numerous October low pressure records
across New England. The tight pressure gradient led to intense
wind gusts region wide which resulted in downed trees and numerous
power outages across the Northeast.
