Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Hurricane Lee is N of the area near 34.4N 67.5W at
5 AM EDT, and is moving north at 14 kt. Maximum sustained winds 
are 75 kt with gusts to 90 kt, and the minimum central pressure 
is 957 mb. Lee will move to 36.8N 67.0W this afternoon, 40.3N 
66.7W Sat morning, weaken as an extratropical cyclone near 43.4N
66.4W Sat afternoon, inland to 46.3N 64.8W Sun morning, 49.3N 
61.1W Sun afternoon, and 52.2N 55.0W Mon morning. Lee will 
dissipate early Tue. Long-period swell generated by Lee is 
expected to impact the waters north and east of the Bahamas 
through Sun morning. High pressure will build briefly across the
area Sun into Mon. Low pressure across the central Atlantic, 
AL97, is expected to approach the ENE part of the area Mon, 
possibly as a tropical cyclone, and track northwestward over
that same area through Wed leading to a significant increase in 
winds and seas.
