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. Slow weakening is forecast during the next few days,
however, Lee is likely to remain a large and dangerous
hurricane into the weekend.
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 estimated minimum central pressure is 952 mb (28.12 inches).

WIND: Tropical storm conditions are expected in Bermuda
starting early Thursday. Hurricane conditions are possible in
portions of down-east Maine on Saturday. Tropical storm conditions
are possible in portions of coastal New England within 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
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.
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
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
