DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the center of Hurricane Fiona was located near latitude 28.6 North, longitude 70.2 West. Fiona is moving toward the north-northeast near 15 mph (24 km/h). A north- northeastward or northeastward motion with an increase in forward speed is expected through Friday, followed by a somewhat slower northward motion beginning Friday night or Saturday. On the forecast track, the center of Fiona will pass just to the west of Bermuda tonight, approach Nova Scotia on Friday, and move across Nova Scotia and into the Gulf of St. Lawrence on Saturday. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that the 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. Little change in strength is expected today. Some weakening is expected to begin tonight or Friday, but Fiona is forecast be a large and powerful post-tropical cyclone with hurricane-force winds when it moves over Nova Scotia Friday night and Saturday. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). A NOAA Saildrone located about 50 miles east of the center has recently reported sustained winds of 77 mph (124 km/h). The latest minimum central pressure based on data from an Air Force Reserve reconnaissance 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: Hurricane conditions are expected on Bermuda beginning tonight and continuing through Friday morning. Hurricane conditions are possible in portions of the hurricane watch area in Canada by late Friday night. Tropical storm conditions are possible in portions of the tropical storm watch area in Canada by late Friday. RAINFALL: Fiona is forecast to produce the following rainfall: Bermuda: 2 to 4 inches. Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6 inches, with local maximum up to 10 inches. This rainfall could result in areas of flooding, some of which may be significant in nature. Eastern Newfoundland: 1 to 3 inches. Eastern Quebec: 2 to 5 inches. Eastern New Brunswick: 1 to 3 inches. STORM SURGE: A storm surge will cause elevated water levels along the coast of Bermuda in areas of onshore winds beginning tonight. 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 over the next day or so. The swells will also reach Atlantic Canada on Friday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
