Fiona, now a post-tropical cyclone after a destructive run as a hurricane, has already washed away homes, toppled trees and left thousands without power along the Atlantic coast of Canada after the storm made landfall early Saturday. The Canadian Hurricane Centre called Fiona a "historic storm for eastern Canada" and a "potential landmark weather event" in a region where hurricanes are relatively rare. Many storms weaken when they reach colder waters. Fiona is forecast to maintain hurricane-force winds until Saturday afternoon, according to the U.S. National Hurricane Center. It is expected to gradually weaken in the next few days. Forecasters also warned Fiona could bring widespread power outages, and about 400,000 Nova Scotia Power customers were without power Saturday morning, the company reported. 📸: This September 24, 2022, image courtesy of Michael King, special adviser to Newfoundland and Labrador Premier Andrew Furey and his family, shows damage caused by post-tropical storm Fiona -- including a floating residential structure -- on the Burnt Islands, in the Newfoundland and Labrador Province of Canada.
