Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A large non-tropical area of 994 mb low pressure located over the central subtropical Atlantic about 800 miles northeast of the northern Leeward Islands, near 28N53W continues to produce a large area of disorganized showers and thunderstorms. Storm force NE winds have developed N of the center. Environmental conditions appear marginally conducive for development and a subtropical or tropical storm could form within the next day or two. By Thursday night or early Friday, the low will move northeastward over cooler waters and interact with a mid-latitude trough, limiting the chance for additional subtropical or tropical development of the system. Regardless of development, winds on the northern and western portions of this low will be storm force through tonight. Gales will then continue in NE waters through Thu. Overall, there is a medium 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 weekend, with large E swell reaching the Florida offshore waters N of 26N early Fri through Sat.
