DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Post-Tropical Cyclone Teddy was located near latitude 44.5 North, longitude 62.7 West. The post-tropical cyclone is moving toward the north-northeast near 23 mph (37 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 eastern Nova Scotia later today, and then near or over Newfoundland by tonight, and be east of Labrador on Thursday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Some weakening is forecast during the next day or so, but Teddy should remain a strong post-tropical cyclone while passing over Nova Scotia and near Newfoundland. Tropical-storm-force winds extend outward up to 520 miles (835 km) from the center. A sustained wind of 45 mph (72 km/h) and a gust to 57 mph (94 km/h) were reported at Brier Island along the western coast of Nova Scotia within the past few hours. The estimated minimum central pressure is 957 mb (28.26 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Teddy can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC and on the web at https://www.hurricanes.gov/text/MIATCDAT5.shtml. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near and to the east of where the center makes landfall in Nova Scotia. Near the coast, the surge will be accompanied by very large and destructive waves. 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. Tropical storm conditions could begin in the watch areas later this morning. Tropical storm conditions are expected to begin in the Newfoundland warning area this afternoon. 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.
