The Canadian Hurricane Centre has discontinued the Tropical Storm Watch from Fort Lawrence to Digby Nova Scotia, and from west of Brule to Tidnish. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * South coast of Nova Scotia from Ecum Secum to Meat Cove * Port aux Basques to Francois Newfoundland A Tropical Storm Watch is in effect for... * Meat Cove to Brule Nova Scotia * Magdalen Islands Quebec * Prince Edward Island A Tropical Storm Warning means that tropical storm conditions are expected within the warning area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area. Interests elsewhere in Atlantic Canada should monitor the progress of Teddy. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- Teddy made landfall near Ecum Secum, Nova Scotia, near 800 AM AST (1200 UTC), with maximum sustained winds near 65 mph (100 km/h), and a minimum central pressure of 964 mb (28.47 inches). At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone Teddy was located near latitude 46.0 North, longitude 61.3 West. The post-tropical cyclone is moving toward the north-northeast near 26 mph (43 km/h), and this motion with an increase in forward speed is expected for the next day or so. On the forecast track, the center will move over the Gulf of St. Lawrence this afternoon, be near Newfoundland early tonight, and be east of Labrador on Thursday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Teddy should slowly weaken today before dissipating on Thursday. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. A sustained wind of 52 mph (83 km/h) and a gust to 67 mph (107 km/h) were recently reported at Hart Island along the eastern coast of Nova Scotia. The estimated minimum central pressure is 967 mb (28.56 inches).

STORM SURGE: Coastal flooding is still possible over portions of eastern Nova Scotia east of Ecum Secum. Near the coast, large and destructive waves are likely. SURF: Large swells generated by Teddy are affecting Bermuda, the Lesser Antilles, the Greater Antilles, the Bahamas, the east coast of the United States, and Atlantic Canada. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. WIND: Tropical storm conditions are occurring in the Nova Scotia warning area and are expected to begin in the Newfoundland warning area this afternoon. Tropical storm conditions are possible in the watch areas today. RAINFALL: Through Thursday, Teddy is expected to produce rainfall accumulations of 2 to 4 inches (50 to 100 mm) with isolated totals of 6 inches (150 mm) across sections of Atlantic Canada.
