Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Showers and thunderstorms have increased since last 
evening near a large non-tropical area of 980 mb low pressure 
located over the central subtropical Atlantic about 850 miles 
east- southeast of Bermuda, near 29N51W. However, the system 
remains embedded within a frontal zone, which is expected to 
become more pronounced later today as the low begins to move 
east- northeastward at 20 to 25 mph toward colder waters and 
interact with a mid-latitude trough. Therefore, while the system
could show some subtropical characteristics today, its chances
to fully transition to a subtropical or tropical cyclone appear 
to be decreasing. Nevertheless, significant non-tropical 
development of this low is expected during the next couple of 
days. Storm conditions will move E of the area today, but gales 
will prevail into tonight in the far NE waters. Overall, there is
a low chance of subtropical or tropical development within the 
next 48 hours. Large long-period north to northeast swell will 
impact the Atlantic waters and Caribbean Passages between the 
southeastern Bahamas and the E Caribbean producing high seas into
the start of next week, with large E swell reaching the Florida 
offshore waters N of 26N early Fri through Sat.
