Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Hurricane Lee is near 31.7N 68.3W at 5 PM EDT, and 
is moving north at 13 kt. Maximum sustained winds are 75 kt with 
gusts to 90 kt, and the minimum central pressure is 957 mb. Lee 
will maintain intensity as it lifts north of the area, passing to
the west of Bermuda this evening and reaching near 33.8N 67.9W 
late tonight. Lee will continue to move farther away from the 
area through Fri and weaken as an extratropical cyclone well 
north of the area over the NW Atlantic by Sat evening. 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.
