Violent storms passed through portions of St. Lawrence County last night, causing power outages and downed tree limbs. As of about 10 a.m. this morning, National Grid still reported 911 power outages primarily in Canton, Russell, Gouverneur and Piercefield. Chris Chapin of Potsdam caught this massive display of lightning from the safety of his window, overlooking his backyard. View another photo of severe tree damage in Canton.
