was located near latitude 48.0 North, longitude 62.0 West. The
post-tropical cyclone is moving toward the northeast near 22 mph (35

expected over the next couple of days, taking Lee over Newfoundland
later today and over the Atlantic waters by early Monday.
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Continued gradual weakening is forecast during the next couple of
days, and Lee could dissipate on Tuesday.
Tropical-storm-force winds extend outward up to 290 miles (465 km)
from the center.
The estimated minimum central pressure is 989 mb (29.21 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: Wind gusts to near gale force are still possible over
portions of Atlantic Canada today.
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.
