A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. Interests elsewhere in the northeastern United States and Atlantic Canada should monitor the progress of Lee. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 PM AST (1800 UTC), the center of Hurricane Lee was located near latitude 31.0 North, longitude 68.4 West. Lee is moving toward the north near 14 mph (22 km/h) and this general motion with an increase in forward speed is expected through Saturday. A turn toward the north-northeast and then northeast is forecast Saturday night and Sunday. On the forecast track, the center of Lee will pass west of Bermuda through this evening, approach the coast of New England and Atlantic Canada Friday and Saturday, and move across Atlantic Canada Saturday night and Sunday. Data from Air Force Reserve and NOAA reconnaissance aircraft indicate that the maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Gradual weakening is forecast, but Lee is expected to remain a large and dangerous hurricane for the next couple of days. Lee is a large hurricane. Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm-force winds extend outward up to 310 miles (500 km). A sustained wind of 39 mph (63 km/h) with a gust to 51 mph (81 km/h) has recently been reported at the L.F. Wade International Airport on Bermuda. NOAA buoy 41048 located about 90 miles (145 km) northwest of the center of Lee has recently reported a peak one-minute sustained wind of 54 mph (86 km/h) and a gust to 67 mph (107 km/h). The latest minimum central pressure estimated from reconnaissance aircraft data is 957 mb (28.26 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 will continue on Bermuda through Friday. Hurricane conditions are possible in the Hurricane Watch areas in Down East Maine and in Atlantic Canada on Saturday. Tropical storm conditions are expected to begin in Cape Cod, Martha`s Vineyard, and Nantucket on Friday afternoon. Tropical storm conditions are possible in the Tropical Storm Watch area elsewhere in coastal New England and Atlantic Canada late Friday into Saturday. STORM SURGE: The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Chatham, MA to Sagamore Beach, MA...2-4 ft Cape Cod Bay...2-4 ft Nantucket...2-4 ft Sagamore Beach, MA to Border of US/Canada...1-3 ft Boston Harbor...1-3 ft Flushing, NY to Chatham, MA...1-3 ft Montauk Point, NY to Flushing, NY...1-3 ft Long Island Sound...1-3 ft Martha`s Vineyard...1-3 ft Rockaway Inlet, NY to Montauk Point, NY...1-2 ft The deepest water will occur along the immediate coast where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. A dangerous storm surge could produce coastal flooding within the wind watch areas in Atlantic Canada in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Lee are affecting portions of the Lesser Antilles, the British and U.S. Virgin Islands, 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: Outer rain bands from Lee may produce rainfall amounts of 1 to 2 inches, or 25 to 50 millimeters, across Bermuda today into early Friday. Friday night through Saturday night, Lee is expected to produce rainfall amounts of 1 to 4 inches, or 25 to 100 millimeters, across portions of eastern New England into portions of New Brunswick and Nova Scotia. This may produce localized urban and small stream flooding. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Brown |
