DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Dorian was located near latitude 51.0 North, longitude 57.5 West. The post-tropical cyclone is moving toward the northeast near 23 mph (37 km/h) and this motion is forecast to continue tonight. A motion toward the east-northeast is expected Monday through Tuesday. On the forecast track, the center of the post-tropical cyclone should move near or over northern Newfoundland or eastern Labrador during the next few hours, then move away from Atlantic Canada later tonight. Maximum sustained winds have decreased to near 65 mph (100 km/h) with higher gusts. The post-tropical cyclone should continue to weaken, and it is forecast to be absorbed by another low pressure system on Tuesday. Tropical-storm-force winds extend outward up to 355 miles (575 km) from the center. Daniel's Harbor, Newfoundland, recently reported sustained winds of 39 mph (63 km/h) and a gust of 63 mph (101 km/h). The estimated minimum central pressure is 968 mb (28.59 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected in the Tropical Storm Warning area tonight. STORM SURGE: A dangerous storm surge is likely in the northeastern Gulf of St. Lawrence and the West Coast of Newfoundland. RAINFALL: Dorian is expected to produce rainfall accumulations of 1 to 2 inches across far eastern Quebec into Newfoundland and Labrador. SURF: Large swells are affecting the coast of Atlantic Canada, and they will continue to affect that area during the next couple of days. Swells along the mid-Atlantic and New England coasts of the U.S. will continue for another day or so. These swells are likely to cause life-threatening surf and rip current conditions.
