At 800 PM AST (0000 UTC), the center of Post-Tropical Cyclone Lee
was located near latitude 44.7 North, longitude 66.3 West. The

or so, taking the system across the Canadian Maritimes.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Steady weakening is forecast during the next couple of days.

Tropical-storm-force winds extend outward up to 320 miles (520 km)
from the center. An observing site on Beaver Island, Canada,
reported a sustained wind of 48 mph (78 km/h) and a gust to 63 mph
(102 km/h).

The estimated minimum central pressure is 979 mb (28.91 inches).

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 are occurring along the coasts of
Maine and Nova Scotia and will spread northward within the Tropical
Storm Warning areas through tonight. The strong winds are leading
to downed trees and power outages.

SURF: Swells generated by Lee are affecting 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 may produce an additional 1 to 2 inches of rain, or
25 to 50 millimeters, over portions of eastern Maine and New
Brunswick. This may produce localized urban and small stream
flooding.

STORM SURGE: A dangerous storm surge will produce coastal flooding
within the wind warning areas in Atlantic Canada in areas of
onshore winds. Near the coast, the surge will be accompanied by
large and destructive waves.
