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).


HAZARDS AFFECTING LAND
----------------------
Key messages for Lee can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC and on the
web at hurricanes.gov/text/MIATCDAT3.shtml

WIND: Tropical storm conditions continue in portions of the
warning areas today. The strong winds could lead to some downed
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.

STORM SURGE: Areas of coastal flooding should gradually subside
today.
