DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the center of Hurricane Teddy was located near latitude 30.5 North, longitude 63.0 West. Teddy is moving toward the north-northeast near 9 mph (15 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 100 mph (155 km/h) with higher gusts. Little change in strength is expected during the next day or so. Gradual weakening is forecast to begin mid-week, but 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. Teddy is a large hurricane. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). An Air Force Reserve Hurricane Hunter aircraft recently reported a minimum central pressure of 960 mb (28.35 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.
