Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...An elongated area of low pressure located N of area and more than 100 miles off the coast of South Carolina is producing disorganized showers and thunderstorms well to the east of its center of circulation. Strong upper-level winds should prevent any significant tropical or subtropical development during the next few days. By late this weekend, the low is expected to interact with a frontal boundary located to its north, which should end the opportunity for tropical or subtropical formation. The frontal boundary is forecast to move slowly across the NW Bahamas and south Florida during the upcoming weekend. ATLC waters from 27N to 31N W of 77W .TODAY...W winds less than 10 kt.
