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.
