Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in Atlantic Canada should monitor the progress of this system. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the eye of Hurricane Fiona was located near latitude 35.9 North, longitude 64.2 West. Fiona is moving toward the northeast near 35 mph (56 km/h). A slower north-northeast or north motion is expected later today through Sunday. On the forecast track, the center of Fiona will approach Nova Scotia later today, move across Nova Scotia and into the Gulf of St. Lawrence on Saturday, and then across Labrador and over the Labrador Sea on Sunday. Maximum sustained winds are near 130 mph (215 km/h) with higher gusts. Fiona is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Although gradual weakening is forecast, Fiona is expected to be a powerful hurricane-force cyclone when it moves across Atlantic Canada. Hurricane-force winds extend outward up to 115 miles (185 km) from the center and tropical-storm-force winds extend outward up to 345 miles (555 km). The minimum central pressure based on data from an Air Force Hurricane Hunter aircraft is 936 mb (27.64 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: Tropical storm conditions are expected on Bermuda during the next few hours. Hurricane conditions are expected in portions of the hurricane warning area in Canada late tonight or early Saturday. Tropical storm conditions are expected in portions of the tropical storm warning area in Canada later today. Tropical storm conditions are possible in the watch area in Labrador on Sunday. RAINFALL: Fiona is forecast to produce the following rainfall: Bermuda: Rainfall is diminishing. No additional significant rainfall expected. Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6 inches (75 to 150 mm), with local maximum up to 10 inches (250 mm). This rainfall could result in areas of flooding, some of which may be significant in nature. Newfoundland 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 could 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 the Turks and Caicos Islands, the Bahamas, the southeastern United States coast, and Bermuda. These swells will continue to spread northwestward across the western Atlantic toward the mid-Atlantic and northeast coasts of the United States and Atlantic Canada today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
