For the North Atlantic, Caribbean Sea and the Gulf of America:
Eastern Tropical Atlantic: Showers and thunderstorms associated with a tropical wave located southeast of the Cabo Verde Islands remain disorganized. Some slow development is possible during the next day or two while the system moves generally west-northwestward at about 10 mph. By this weekend, the system is forecast to move into a less conducive environment, and further development is not expected. * Formation chance through 48 hours, low, 10 percent. * Formation chance through 7 days, low, 10 percent.
Northeastern Gulf of America and Offshore of the Southeastern U.S.: An area of low pressure is forecast to form this weekend over the northeastern Gulf of America. Some gradual development of this system is possible while it moves slowly northeastward over the northeastern Gulf and near the coast of the southeastern United States early next week. * Formation chance through 48 hours, low, near 0 percent. * Formation chance through 7 days, low, 20 percent.

Special Feature
Caribbean Gale Warning: A tight pressure gradient between high pressure north of the basin and the Colombian low will support fresh to strong NE-E winds in the south-central Caribbean during the next several days. Winds will pulse to gale-force across the waters N of Colombia each night through Sat night. Rough to very rough seas will prevail with these winds.

Tropical Waves
An eastern Atlantic tropical wave is analyzed along 23W, south of 16N, moving westward at 5-10 kt. Scattered moderate convection is present from 11N to 13N and between 22W and 24W and remains disorganized. Some slow development is possible during the next couple of days while the system moves generally west-northwestward at about 10 mph. By this weekend, the system is forecast to move into a less conducive environment, and further development is not expected. The disturbance has a low chance of development over the next 7 days.
An eastern Atlantic tropical wave is along 37W, south of 18N, moving westward at 15-20 kt. No significant convection is noted with this wave at this time.
Monsoon Trough/ITCZ
The monsoon trough enters the Atlantic through the coast of Africa near 19N16W and continues southwestward to a 1012 mb low pres near 11N23W to 09N36W. The ITCZ extends from 10N40W to 09N60W. Scattered moderate convection is present from 08N to 13N and between 18W and 28W
Gulf Of America
A 1021 mb high pressure system positioned over southeast Louisiana. A surface trough is analyzed over the Yucatan Peninsula. The pattern is supporting moderate E to SE winds across the south- central Gulf and western Gulf, with 3-5 ft seas. Light to gentle breezes are noted over elsewhere with 1-3 ft seas. No significant convection is evident across the Gulf at this time.
For the forecast, fresh to strong winds will pulse offshore the Yucatan Peninsula each night. Gentle to moderate winds, and slight to moderate seas, will prevail elsewhere.
Looking ahead, an area of low pressure is forecast to form this weekend over the northeastern Gulf of America. Some gradual development of this system is possible while it moves slowly northeastward over the northeastern Gulf and near the coast of the southeastern United States early next week, although chances of development remain low through the next seven days.
Caribbean Sea
A Gale Warning is in effect for the south-central Caribbean offshore of Colombia. Please refer to the Special Features section for more details.
The Atlantic subtropical ridge centered north of the Caribbean forces strong to gale easterly trade winds across the central Caribbean, with the strongest winds occurring off Colombia and in the Gulf of Venezuela. Rough to very rough seas are found in these waters. Fresh NE winds and moderate seas are noted in the Windward Passage and Gulf of Honduras. Meanwhile, moderate to fresh easterly winds and moderate seas are present in the eastern Caribbean. Elsewhere, moderate or weaker winds and slight to moderate seas are prevalent. No significant convection is evident across the Gulf at this time.
For the forecast, the pressure gradient between high pressure north of the basin and the Colombian low will support pulsing NE winds to gale-force across the waters N of Colombia each night through Sat night. Otherwise, strong to near-gale trade winds and rough seas will prevail across the central Caribbean into the middle of next week. East winds will pulse fresh to strong each evening in the Gulf of Honduras and Windward Passage.
Atlantic Ocean
A broad ridge extends across the Atlantic basin north of 15N, anchored by 1025 mb centered near 29N44W. Gentle to moderate NE to E winds and 3-5 ft seas is noted along the ridge axis north of 15N and west of 35W, and moderate to fresh NE to E winds and 4-6 ft are noted elsewhere.
For the forecast west of 55W, the ridge will remain dominant through the forecast period. The weather pattern will support moderate to fresh trades south of 25N, with gentle winds to the north. Pulsing strong winds are expected each night offshore Hispaniola and in the Windward Passage.
