DISCUSSION AND OUTLOOK
———————-
At 500 AM AST (0900 UTC), the center of Hurricane Teddy was located
near latitude 30.3 North, longitude 63.2 West. Teddy is moving
toward the north 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).
The estimated minimum central pressure is 963 mb (28.44 inches).
