DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Hurricane Teddy was located near latitude 39.3 North, longitude 63.5 West. Teddy is moving toward the north-northwest near 28 mph (44 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.
Maximum sustained winds are near 105 mph (165 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 a large hurricane. Hurricane-force winds extend outward up to 105 miles (165 km) from the center and tropical-storm-force winds extend outward up to 400 miles (645 km).
The estimated minimum central pressure is 950 mb (28.05 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected to begin in the warning area by this afternoon. Tropical storm conditions could begin in the watch areas late today or early Wednesday.
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: 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.
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.
