Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Low pressure near 31N77W 1011 mb will continue to track northeastward to north of the area near 33N73W 1009 mb by early Mon. A trough will trail from the low to near West Palm Beach. Unsettled weather in the form of scattered to numerous showers and thunderstorms, some with strong gusty winds and rough seas, are expected over the waters between 72W and 80W the next couple of days. Environmental conditions appear conducive for gradual development of the low pressure system, and a tropical or subtropical depression is likely to form within the next few days as the low tracks to the NE north of the area. Otherwise, gentle to moderate southeasterly winds will continue across the area. Tropical Storm Dorian, currently in the tropical Atlantic, is forecast to move across the eastern Caribbean Sea as a hurricane by the middle of the week and near the far southeast waters as a tropical storm by late in the week. Expect increasing winds and building over those waters with the approach of Dorian. ATLC waters from 27N to 31N W of 77W .THIS AFTERNOON...NW winds 10 to 15 kt.
