DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Dorian was located near latitude 43.9 North, longitude 63.9 West. The post-tropical cyclone is moving toward the northeast near 30 mph (48 km/h), and this general motion is expected to continue for the next 24 hours. After that, a turn toward the east-northeast is expected. On the forecast track, the center of Dorian should cross the coast of Nova Scotia near Halifax during the next few hours, then move across eastern Nova Scotia into the Gulf of St. Lawrence near Prince Edward Island tonight. The center should then pass near or over northern Newfoundland and eastern Labrador late tonight or Sunday morning. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. The post-tropical cyclone is expected to weaken during the next couple of days, and it is forecast to drop below hurricane strength by Sunday morning. Hurricane-force winds extend outward up to 115 miles (185 km) to the south of the center and tropical-storm-force winds extend outward up to 310 miles (500 km). Osbourne Head, Nova Scotia, recently reported sustained winds of 68 mph (109 km/h) and a wind gust of 88 mph (142 km/h). The estimated minimum central pressure is 953 mb (28.15 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are spreading across much of Nova Scotia, and hurricane conditions are expected to spread over portions of Nova Scotia during the next few hours.

Tropical storm conditions are expected in the Tropical Storm Warning area tonight and Sunday. Tropical storm conditions are expected in the Tropical Storm Warning area in Maine during the next few hours. STORM SURGE: A dangerous storm surge is likely in the Gulf of St. Lawrence, the Southwest Coast of Newfoundland, and Eastern Nova Scotia. RAINFALL: Dorian is expected to produce the following rainfall totals through Saturday Night: Far eastern Maine...1 to 3 inches. Nova Scotia...3 to 5 inches, isolated 7 inches. New Brunswick and Prince Edward Island...2 to 4 inches Newfoundland and far eastern Quebec...1 to 2 inches These rainfall amounts could result in flash flooding. SURF: Large swells are increasing along the coast in Atlantic Canada, and they will continue to affect that area during the next few days. Swells along the mid-Atlantic and New England coasts of the U.S. will continue for a couple of more days. These swells are likely to cause life-threatening surf and rip current conditions.
