DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Post-Tropical Cyclone Fiona was located near latitude 45.1 North, longitude 61.1 West. The post-tropical cyclone is moving toward the north near 40 mph (64 km/h). A slower north-northeast or northward motion is expected through Sunday. On the forecast track, the center of Fiona will make landfall in eastern Nova Scotia in the next hour or two, then move across eastern Nova Scotia overnight and into the Gulf of St. Lawrence this morning, and then move across Labrador and over the Labrador Sea on Sunday. Maximum sustained winds are near 100 mph (160 km/h) with higher gusts. Although gradual weakening is forecast during the next couple of days, Fiona is expected to maintain hurricane-force winds through this morning. Hurricane-force winds extend outward up to 185 miles (295 km) from the center and tropical-storm-force winds extend outward up to 345 miles (555 km). Beaver Island, Nova Scotia, recently reported sustained winds of 78 mph (126 km/h) and a wind gust of 93 mph (150 km/h). The estimated minimum central pressure is 933 mb (27.55 inches).

HAZARDS AFFECTING LAND ---------------------- Key messages for Fiona can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC and on the web at hurricanes.gov/text/MIATCDAT2.shtml. WIND: Hurricane conditions are now 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. Tropical storm conditions are possible in the watch area in Labrador on Sunday. RAINFALL: Fiona is forecast to produce the following rainfall: Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6 inches (75 to 150 mm), with local maxima of up to 10 inches (250 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 to 3 inches (25 to 75 mm). 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 eastern United States coast, Bermuda, and the northwestern Bahamas. The swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
