DISCUSSION AND OUTLOOK
At 500 PM AST (2100 UTC), the center of Hurricane Teddy was located
near latitude 41.1 North, longitude 64.2 West. Teddy is moving
toward the north 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 90 mph (150 km/h) with higher
gusts. Although some weakening is likely tonight and Wednesday,
Teddy should be a strong post-tropical cyclone when it moves near
and over Nova Scotia.
Teddy is an extremely large hurricane. Hurricane-force winds extend
outward up to 125 miles (205 km) from the center and
tropical-storm-force winds extend outward up to 540 miles (870 km).
Buoy 44150, located about 90 n mi north of the center, recently
reported a significant wave height of 42 ft (13 m).
The estimated minimum central pressure is 958 mb (28.29 inches).

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 now. Tropical storm conditions could begin in the
watch areas tonight or early Wednesday. Tropical storm conditions
are expected to begin in the Newfoundland warning area on 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.
