At 800 PM AST (0000 UTC), the center of Hurricane Teddy was located
near latitude 29.3 North, longitude 63.4 West. Teddy is moving
toward the north near 9 mph (15 km/h) and this general motion is

island Monday morning. Teddy is forecast to be approaching Nova
Scotia late Tuesday or Wednesday.

gusts. Little change in strength is forecast, and the system is
expected to remain a large and powerful hurricane through Tuesday,
then become a strong post-tropical cyclone on Wednesday.
Teddy is a large hurricane. Hurricane-force winds extend outward
up to 80 miles (130 km) from the center and tropical-storm-force
