The October 2017 nor'easter was a major explosive cyclogenesis storm, also called a bomb cyclone, in the Northeastern United States and Atlantic Canada from October 29–31, 2017. Forming from an extratropical cyclone on October 29 the system moved rapidly up the East Coast of the United States, bombing out with a minimum pressure of 975 millibars (28.8 inHg) on October 30. It brought heavy rain and extremely strong winds, and power outages, over 1.3 million customers being without power in the Northeast. Hurricane-force wind gusts resulted in downed trees, power lines, and widespread damage to buildings. The number of power outages in the state of Maine surpassed the Ice Storm of 1998.
