Warnings for Gale-Force winds, and rough to very rough seas, have been issued for parts of the Gulf of Mexico, the NW corner of the Caribbean Sea, and the Atlantic Ocean. These warnings are related to a low pressure center and a cold front that are moving through the Gulf of Mexico and into parts of the northern Caribbean Sea, and through Florida into the Atlantic Ocean. The first weather system, and a second and reinforcing system, will bring hazardous marine conditions to parts of the forecast area through at least Tuesday night. Mariners are urged to exercise caution during the next couple of days: in the Gulf of Mexico, in the Yucatan Peninsula, and in the NW Caribbean Sea, and in the western Atlantic Ocean, including areas that are away from the gale-force wind warning areas. This is due to the expansive area of strong to near-gale force winds that will be associated with the successive weather systems. The large wind fields will build rough to very rough seas.early next week. This bulletin is based on the forecasts that started at 05/0000 UTC, and continue for 48 hours into the future. ...GALE-FORCE WINDS ARE FORECAST FOR THE GULF OF MEXICO, AND FOR THE YUCATAN CHANNEL... A first cold front passes through Florida, to NW Cuba, into the NW Caribbean Sea, to the Isthmus of Tehuantepec of southern Mexico. A squall line has been to the east of the first cold front by 100 nm or so. A second cold front is moving through the central Gulf of Mexico, about 460 nm to the west of the first cold front. Expect gale-force NW winds, and rough to very rough seas, from 25N to 27N between 92W and 94W. Gale-force winds, and rough to very rough seas, will continue to move eastward in the Gulf of Mexico, with the second cold front, during the next 30 hours or so. Moderate to rough seas are in the NW corner of the Gulf of Mexico now. Moderate seas cover the rest of the northern two-thirds of the area, and everywhere from 90W eastward. Slight seas are in the SW corner of the Gulf. ...GALE-FORCE WINDS ARE FORECAST FOR THE CARIBBEAN SEA... Expect at 18 hours: gale-force W to NW winds, and rough to very rough seas, from 21N to 22N between 85W and 86.5W, including in the Yucatan Channel. The gale-force winds, and the rough to very rough seas, will last from 18 hours to 42 hours. ...GALE-FORCE WINDS ARE FORECAST FOR THE ATLANTIC OCEAN... Expect at 30 hours: a 998 mb low pressure center near 30N74W. Gale-force NW winds, and rough to very rough seas, will be from 28N northward between 79W and 82W. These conditions will be continuing up to the 48 hour point in the forecast period. Strong and faster SE winds now are from 28N northward from 75W westward. Fresh to strong SE winds are elsewhere from 23N to 28N between 70W and 77W.

GULF OF MEXICO... A GALE-FORCE WIND WARNING has been issued for the Gulf of Mexico. Please, read the SPECIAL FEATURES section for more details. A deep low pressure system moving across the northeastern and east-central Gulf will keep fresh to strong winds and rough seas through this evening. The attendant cold front will exit to the southeast of the Gulf tonight. Afterward, a second deepening low pressure from southern Texas is going to migrate across the central and eastern Gulf late tonight through Monday night. This next system will bring more gale winds and very rough seas for the central and southeastern Gulf. Mariners are urged to exercise caution across the entire Gulf of Mexico, including outside of the gale warning areas due to the expansive area of strong to near- gale force winds and rough seas associated with these successive weather systems. CARIBBEAN SEA... Please, read the SPECIAL FEATURES section, for information about the GALE-FORCE WIND WARNING for the Yucatan Channel, and for the northwestern part of the Caribbean Sea. Slight to moderate seas are in the NW corner of the area, and in the SE corner of the area. Slight seas are elsewhere in the area.

Precipitation: broken to overcast low level and middle level clouds, and isolated moderate, are spread throughout the area. Southerly wind are starting to increase from eastern Honduras to western Cuba ahead of a weak cold front in the southeastern Gulf of Mexico currently approaching the Yucatan Channel. This front will continue to move into the northwest Caribbean tonight, just ahead of a stronger, reinforcing front that moves through the Yucatan Channel Mon. The fronts will merge from central Cuba to northeast Nicaragua by late Mon, then reach from the Mona Passage to eastern Panama by late Tue. It should weaken as it moves through the eastern Caribbean through mid week. Gale-force winds and rough to very rough seas will follow the front over the northwest Caribbean Mon into Tue.
