SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warning in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone Lee was located near latitude 48.0 North, longitude 62.0 West. The post-tropical cyclone is moving toward the northeast near 22 mph (35 km/h), and a faster northeastward to east-northeastward motion is 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.
