DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Post-Tropical Cyclone Lee
was located near latitude 47.3 North, longitude 63.0 West. The
post-tropical cyclone is moving toward the northeast near 22 mph (35
km/h), and a faster northeastward motion is expected over the next
couple of days, taking Lee over Newfoundland this afternoon and over
the Atlantic waters by early Monday.
 
Maximum sustained winds have decreased to near 45 mph (70 km/h) with 
higher gusts. Continued gradual weakening is forecast during the 
next couple of days, and Lee could dissipate on Tuesday. A number of 
tropical-storm-force wind gusts have been reported across Nova 
Scotia during the past few hours. Beaver Island Nova Scotia 
recently reported a sustained wind of 44 mph (70 km/h) with a gust 
to 54 mph (87 km/h).
 
Tropical-storm-force winds extend outward up to 290 miles (465 km)
from the center.
 
The estimated minimum central pressure based on surface observations 
in Canada is 989 mb (29.15 inches).

trees and power outages.
 
SURF: Swells generated by Lee continue to affect Puerto Rico, 
Hispaniola, the Turks and Caicos Islands, the Bahamas, Bermuda, 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: Lee is expected to produce an additional 1 inch (25 mm)
or less across eastern portions of New Brunswick.
