DISCUSSION AND OUTLOOK
———————-
At 1100 PM AST (0300 UTC), the center of Hurricane Teddy was located
near latitude 35.6 North, longitude 61.5 West. Teddy is moving
toward the north near 25 mph (41 km/h), and this motion is expected
overnight followed by a turn toward the north-northwest on Tuesday.
Teddy should turn toward the north-northeast and move over eastern
Nova Scotia on Wednesday then over the Gulf of St. Lawrence late
Wednesday into Thursday.

Maximum sustained winds have increased to near 100 mph (155 km/h)
with higher gusts. Teddy could gain a little more strength
overnight but should weaken steadily by Wednesday and become a
strong post-tropical cyclone near Nova Scotia.

Hurricane-force winds extend outward up to 105 miles (165 km) from
the center and tropical-storm-force winds extend outward up to 275
miles (445 km).

An Air Force Reserve Hurricane Hunter aircraft recently reported
a minimum central pressure of 956 mb (28.23 inches).

and on the web at www.hurricanes.gov/text/MIATCDAT5.shtml.

WIND: Tropical storm conditions are expected to begin in
the warning area by Tuesday afternoon. Tropical storm conditions
could begin in the watch areas late Tuesday 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: 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.

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.
