DISCUSSION AND OUTLOOK ---------------------- At 200 PM AST (1800 UTC), the center of Post-Tropical Cyclone Fiona was located near latitude 47.7 North, longitude 61.4 West. The post-tropical cyclone is moving toward the north near 25 mph (41 km/h), and a slower northward motion is expected during the next few days. On the forecast track, the center of Fiona will move across the Gulf of St. Lawrence through this evening, and then move across Labrador and over the Labrador Sea on Sunday. Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Gradual weakening is expected during the next couple of days. Hurricane-force winds extend outward up to 115 miles (185 km) from the center and tropical-storm-force winds extend outward up to 405 miles (650 km). The estimated minimum central pressure based on surface observations is 948 mb (28.00 inches). Several observing sites in Atlantic Canada are recording gale- and storm-force winds.

WIND: Hurricane conditions are occurring in portions of the hurricane warning area in Canada. Tropical storm conditions are occurring in portions of the tropical storm warning area in Canada. RAINFALL: Fiona is forecast to produce the following additional rainfall: Nova Scotia, Prince Edward Island, and western Newfoundland: 1 to 3 inches (25 to 75 mm), resulting in storm total rainfall maxima of up to 10 inches (200 mm). Flooding is expected, some of which could be significant. Labrador and eastern Quebec: 2 to 5 inches (50 to 125 mm). Eastern New Brunswick: 1 inch (25 mm) with locally higher amounts. STORM SURGE: A dangerous storm surge is expected to produce coastal flooding within the warning areas in Atlantic Canada in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Fiona are affecting Atlantic Canada, the northeastern United States coast, and Bermuda. The swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
