DISCUSSION AND OUTLOOK
———————-
At 500 PM AST (2100 UTC), the center of Hurricane Teddy was located
near latitude 23.1 North, longitude 57.0 West. Teddy is moving
toward the northwest near 14 mph (22 km/h) and this general motion
is expected to continue for the next couple of days, followed by a
turn toward the north by early next week. On the forecast track,
Teddy will be approaching Bermuda late Sunday or Monday.
NOAA and U.S. Air Force Reserve Hurricane Hunter aircraft reported
that the maximum sustained winds have decreased to near 125 mph (205
km/h) with higher gusts. Teddy is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some fluctuations in strength
are expected through Saturday, and a weakening trend is forecast to
begin late this weekend.
Hurricane-force winds extend outward up to 60 miles (95 km) from the
center and tropical-storm-force winds extend outward up to 230 miles
(370 km).
The minimum central pressure measured by the aircraft is 951 mb
(28.08 inches).

WIND: Tropical storm conditions could begin to affect Bermuda and
the nearby waters by Sunday afternoon. These conditions may linger
throughout most of the day Monday.
SURF: Large swells generated by Teddy are affecting the Lesser
Antilles, the northeastern coast of South America, the Greater
Antilles, and the Bahamas, and will spread to Bermuda and the east
coast of the United States by Saturday. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
