DISCUSSION AND OUTLOOK ---------------------- At 200 PM AST (1800 UTC), the center of Hurricane Teddy was located near latitude 40.3 North, longitude 64.1 West. Teddy is moving toward the north-northwest near 16 mph (26 km/h), and a turn toward the north-northeast is expected by early Wednesday. On the forecast track, the center will move over eastern Nova Scotia on Wednesday, and then near or over Newfoundland by Wednesday night, and be east of Labrador on Thursday. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Although some weakening is likely later today and Wednesday, Teddy should be a strong post-tropical cyclone when it moves near and over Nova Scotia. Teddy is an extremely large hurricane. Satellite-derived winds and a recent NOAA Hurricane Hunter mission indicate that hurricane-force winds extend outward up to 150 miles (240 km) from the center and tropical-storm-force winds extend outward up to 550 miles (890 km). Buoy 44150, located about 150 n mi north of the center, recently reported a significant wave height of 36 ft (11 m). The estimated minimum central pressure is 956 mb (28.23 inches) based on NOAA Hurricane Hunter aircraft data. 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 expected to begin in the warning area soon. Tropical storm conditions could begin in the watch areas late today or early Wednesday. 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.
