Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A stationary front extends from near Bermuda southwestward to near Cape Canaveral, Florida. Fresh to locally strong NE to E winds are north of the front along with seas of 8 to 9 ft. Widely scattered showers and thunderstorms are north of 25N and west of 60W. The front will linger through tonight, then lift back north as a warm front Thu and Thu night. The front may drop south to around 31N again this weekend with the potential for higher winds and seas near and north of it. Elsewhere over the remainder Southwest North Atlantic waters, winds should remain gentle to moderate with slight to moderate seas. Looking ahead, a small but well-defined area of low pressure located several hundred miles to the east of the Leeward Islands is encountering dry air near the system, limiting additional development before environmental conditions become even less conducive by this weekend as it moves slowly west-northwestward. This system has a LOW chance of tropical formation in the next 48 hours. ATLC waters from 27N to 31N W of 77W .THIS AFTERNOON...E winds 10 to 20 kt. Seas 5 to 7 ft. .TONIGHT...E winds 10 to 20 kt.
