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, in this case within the next 24 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, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Lee was located near latitude 28.0 North, longitude 67.7 West. Lee is moving toward the north near 9 mph (15 km/h). A generally northward motion and an increase in forward speed are expected through Friday. On the forecast track, the center of Lee will pass west of Bermuda Thursday and Thursday night and then approach the coast of New England and Atlantic Canada Friday and Saturday. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Some weakening is forecast during the next 48 hours, but Lee is expected to remain a large and dangerous hurricane for the next couple of days. Hurricane-force winds extend outward up to 115 miles (185 km) from the center and tropical-storm-force winds extend outward up to 265 miles (425 km). The minimum central pressure reported by a NOAA Hurricane Hunter aircraft is 953 mb (28.15 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 are expected in Bermuda starting early Thursday. Hurricane conditions are possible in portions of Down East Maine and in the Hurricane Watch area in Atlantic Canada on Saturday. Tropical storm conditions are possible in portions of coastal New England and Atlantic Canada in the Tropical Storm Watch area beginning Friday night. 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 are beginning to reach 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 could produce rainfall amounts of 1 to 2 inches, or 25 to 50 millimeters, across Bermuda Thursday into early Friday. From 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 could produce localized urban and small stream flooding. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM AST. Next complete advisory at 500 AM AST. $$ Forecaster Pasch |
