Fiona's center will then approach Nova Scotia on Friday, move across Nova Scotia and into the Gulf of St. Lawrence on Saturday, and then across Labrador over the Labrador Sea on Sunday. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that Maximum sustained winds remain near 130 mph (215 km/h) with higher gusts. Fiona is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some slight weakening is forecast to begin tonight or on Friday, however Fiona is forecast to be a large and powerful post-tropical cyclone with hurricane-force winds when it approaches and moves over Nova Scotia Friday night and Saturday. Hurricane-force winds extend outward up to 115 miles (185 km) from the center and tropical-storm-force winds extend outward up to 275 miles (445 km).
