DISCUSSION AND OUTLOOK
———————-
At 1100 AM AST (1500 UTC), the center of Hurricane Teddy was located
by a NOAA Hurricane Hunter aircraft near latitude 39.6 North,
longitude 63.7 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 east of Labrador on Thursday.
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 an extremely large hurricane. Hurricane-force winds extend
outward up to 140 miles (220 km) from the center and
tropical-storm-force winds extend outward up to 415 miles (665 km).
The estimated minimum central pressure is 950 mb (28.06 inches)
based on NOAA Hurricane Hunter aircraft data.

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 by this afternoon. 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.
