A weak frontal boundary extends from north central Florida, to the NW corner of the Gulf of Mexico, to the coast of Mexico near 21N98W. The eastern part of the front will move through the southeast Gulf of Mexico tonight. The rest of the front will stall and dissipate in the western Gulf of Mexico. The winds and seas will diminish in the Gulf on Friday and Saturday, as weak ridging builds in the north part of the Gulf. A new cold front will move across the N and central Gulf of Mexico on Sunday and Monday, with enhanced NW to N winds building in behind the front. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A moderate pressure gradient south of the Bermuda High will be forcing strong to gale force winds across the S central Caribbean Sea, and to near the coast of Colombia for the rest of the morning hours. A large extratropical cyclone east of the mid-Atlantic states will reduce the gradient through Monday, weakening the NE tradewinds to fresh breezes or less across the Caribbean Sea. Large N swell on Saturday will begin impacting the offshore Atlantic waters east of the Lesser Antilles and continue through at least Monday night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Weakening high pressure across the area will shift eastward through today, in response to an approaching cold front. This cold front will move quickly across the area through Friday. Enhanced NW to N wind will be building in behind the front. Associated large NW to N swell will spread across the area on Saturday, and it will diminish by early Monday. The winds will become quiescent from Saturday to early Sunday. A second cold front will reach the far NW waters on Sunday night. The second cold front will move across the area through Monday. Strong to possibly gale force winds are expected on either side of the front, to the northeast of the Bahamas, early next week. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
