Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Hurricane Lee is near 32.9N 67.6W at 11 PM EDT, and 
is moving north at 12 kt. Maximum sustained winds are 75 kt with
gusts to 90 kt, and the minimum central pressure is 957 mb. Lee 
will move to 35.0N 67.3W Fri morning, 38.4N 66.6W Fri evening, 
41.6N 66.6W Sat morning, move inland and weaken to a tropical 
storm near 44.3N 66.0W Sat evening, become extratropical and
move to 47.0N 63.6W Sun morning, and 49.6N 59.1W Sun evening. 
Lee will change little in intensity as it moves near 54.5N 42.5W 
late Mon. Long-period swell generated by Lee is expected to 
impact all waters north through east of the Bahamas through the 
weekend. High pressure will build across the area late Fri 
through Sun. Low pressure across the eastern Atlantic, AL97, is 
expected to approach the northeast part of the area Mon, possibly
as a tropical cyclone, and track northwestward over that same 
area through Tue night leading to a significant increase in winds
and seas.
