  areas from Northern New York in January 1998. It
  caused massive damage to trees and electrical
  infrastructure all over the area, leading to
  widespread long term power outages. Millions were
  left in the dark for periods varying from days to
  weeks, leading to more than 30 fatalities, a shut

  effort of the power grid.
