Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...Low pressure centered about 90 nm northeast of Cabo Gracias a Dios, Honduras is gradually becoming better organized. Environmental conditions appear conducive for some additional development over the next couple of days. A short-lived tropical depression or storm could form before the system moves inland over Belize and the Yucatan Peninsula of Mexico on Sat. Farther north, fresh to strong winds and rough seas follow a cold front moving slowly over the Yucatan Channel. This front will dissipate through late Fri ahead of the developing low to the south. Meanwhile, fresh to strong winds, rough seas and scattered thunderstorms accompany a trough moving westward to the north of the Leeward Islands into Fri morning. Looking ahead, winds and seas will diminish across the basin early next week. NW Caribbean W of 85W .OVERNIGHT...NE winds 15 to 25 kt. Seas 6 to 9 ft. .SAT...SE winds 20 to 30 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from just west of Bermuda to central Cuba will move slowly eastward overnight into Fri, stall late Fri, then dissipate through Sat night into Sun. Fresh to strong NE winds and rough seas will continue to affect the waters W of the front into early next week when conditions will start to improve. Farther south, Invest AL94 is weakening as it moves to the north of the Leeward Islands. Development, if any, of this disturbance should be slow to occur while it moves quickly westward to west-northwestward at around 15 to 20 kt, passing near the Virgin Islands and Puerto Rico on Fri, then near Hispaniola and the southeastern Bahamas on Sat. By late this weekend, further development is not expected due to strong upper-level winds. ATLC waters from 27N to 31N W of 77W .OVERNIGHT...NE winds 15 to 25 kt.
