DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Hurricane Teddy was located near latitude 29.7 North, longitude 63.5 West. Teddy is moving toward the north near 6 mph (9 km/h). Although some fluctuations in heading are likely, the hurricane is expected to move generally northward through Tuesday evening, followed by a turn toward the northeast on Wednesday. The center of Teddy will pass east of Bermuda today and then approach Nova Scotia late Tuesday or early Wednesday. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Some slight strengthening is possible Monday night while Teddy begins to interact with an approaching frontal system. Although gradual weakening is forecast to begin mid-week, the cyclone is expected to remain a large and powerful hurricane Tuesday, then become a strong post-tropical cyclone when it nears Nova Scotia by Wednesday morning. Hurricane-force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). NOAA buoy 41049, located about 150 miles (240 km) south-southeast of the center of Teddy recently reported sustained winds of 49 mph (79 km/h) and a gust to 60 mph (97 km/h). The estimated minimum central pressure is 963 mb (28.44 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. WIND: Tropical storm conditions are expected to affect Bermuda into Monday night. Tropical storm conditions could begin over Nova Scotia on Tuesday afternoon. 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. RAINFALL: From Tuesday 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.
