DISCUSSION AND OUTLOOK
At 200 PM AST (1800 UTC), the center of Hurricane Teddy was located
from satellite imagery and Bermuda radar near latitude 32.2 North,
longitude 62.0 West. Teddy is moving toward the north-northeast
near 18 mph (30 km/h), and this motion with some increase in
forward speed is expected to continue today, followed by a turn
toward the north tonight and north-northwest on Tuesday. Teddy
should turn to the north-northeast and decelerate as it approaches
Nova Scotia on Wednesday.
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Teddy is expected to gain strength overnight, but weaken
steadily by Wednesday and become a strong post-tropical cyclone.
