Special Features

Gulf of America Gale Warning: A strong cold front will enter the NW Gulf waters early Mon. The front will move quickly southeastward, departing the basin Tue night. Fresh to near gale- force winds will follow the front, along with rough seas. Gale- force N winds and rough to very rough seas will develop off Tampico Mon. These winds and seas will reach the waters off Veracruz Mon night and persist until Tue night. Seas may peak around 20 ft off Veracruz Mon night into Tue. Conditions will improve from north to south by midweek.

Central Atlantic Gale and Significant Swell: A couple of cold fronts are moving through the north central waters. The first cold front extends from 31N47W to 27N76W. The second cold front enters the waters near 31N51W to 27N63W to 31N75W. A recent scatterometer satellite pass indicate that strong to locally gale-force cyclonic winds are occurring north of 25N and between 40W and 60W. Fresh to strong W to NW winds and very rough seas will continue over the central tropical Atlantic, north of 22N and east of 65W, through Mon morning. Near-gale to gale force winds will impact the waters north of 29N and east of 60W through late tonight. Large N swell from both fronts is leading to very rough seas greater over the forecast waters N of 23N between 37W and 68W. Widespread rough seas associated with this storm system will prevail east of 75W through tonight before briefly subsiding from west to east early this week.

Monsoon Trough Itcz

The monsoon trough reaches the Atlantic through the coast of Guinea near 10N14W and continues to 04N20W. The ITCZ continues from 04N20W to 02N33W and to 00N48W. A few showers are noted near the monsoon trough and ITCZ.

Gulf Of America

Please read the Special Features section above on an upcoming Gale Warning.

A weak pressure pattern dominates the Gulf waters ahead of an approaching cold front, currently over the southern United States. A recent scatterometer satellite pass captured moderate to locally fresh easterly winds and moderate seas south of 24N. Light to gentle winds and slight to moderate seas prevail elsewhere.

For the forecast, a cold front will move into the northern Gulf late tonight. The front will rapidly shift across the Gulf waters, moving SE of the area Tue. Gale force winds and rough seas are expected in the wake of the front off the coast of Texas and Louisiana by early Mon morning, and offshore of Tampico and Veracruz by Mon afternoon and night. Prolonged gale force winds and significant very rough seas will persist over the western Bay of Campeche through late Tue night. Widespread strong to near-gale force winds and rough seas are expected elsewhere behind the front. Winds and seas will diminish from north to south through midweek. High pressure will build over the basin following the front with moderate or weaker winds and moderate seas through late this week.

Caribbean Sea

A strong pressure gradient persist across the central Caribbean Sea between the subtropical ridge centered north of the islands and lower pressures associated with the Colombian low. A recent scatterometer satellite pass captured strong to near gale-force easterly trade winds in the south-central Caribbean. Seas in these waters are 8-10 ft. Fresh to locally strong easterly breezes and moderate seas are noted in the north- central Caribbean. Elsewhere, moderate or weaker winds and moderate seas prevail. Low-level convergence is producing a few showers in the NW Caribbean and off NE Nicaragua. In the meantime, a surface trough near the Windward Islands is generating scattered showers in the SE Caribbean.

For the forecast, fresh to occasionally strong trade winds and rough seas are expected over the central Caribbean through the middle of the week as a moderate pressure gradient prevails between the Colombian low and high pressure to the north. Winds may reach near-gale force offshore of northern Colombia tonight and again Mon night. Moderate to occasionally fresh trade winds and moderate seas are expected over the rest of the basin through midweek. Elsewhere, a long period N to NW swell will bring rough seas over the Atlantic waters this week. A cold front will move into the northwestern basin late Tue into Wed, and weaken as it moves southeastward and dissipates on Thu.

Atlantic Ocean

See the Special Features section above for details on gale force winds and the ongoing significant swell in the central Atlantic.

In the north-central tropical Atlantic, the aforementioned cold fronts are producing scattered showers and isolated thunderstorms, especially east of the fronts to 40W and north of 25N. Rough seas are evident High pressure dominates the SW North Atlantic, supporting moderate or weaker winds and seas of 5-9 ft west of 65W. A surface trough is analyzed just east of the Lesser Antilles, producing a few showers and thunderstorms near and east of the archipelago. Elsewhere in the tropical Atlantic, a weak subtropical ridge maintains moderate or weaker winds and moderate to locally rough seas.

For the forecast west of 55W, fresh to strong W to NW winds and very rough seas will continue over the central tropical Atlantic, north of 22N and east of 65W, through Mon morning as a strong storm system and a series of cold fronts move over the region. Near- gale to gale force winds will impact the waters north of 29N and east of 60W through late tonight. Widespread rough seas associated with this storm system will prevail east of 75W through tonight before briefly subsiding from west to east early this week. Farther west, fresh to locally strong W to SW winds will develop offshore of Florida on Mon ahead of a cold front moving through the southern U. S. The front will move offshore by late Mon, supporting fresh to strong W to NW winds and rough seas in the wake of the front. These winds and seas will expand eastward toward the central Atlantic through midweek as the front moves eastward. Another cold front is expected to enter the northwest tropical Atlantic late this week, supporting increasing winds and building seas near and behind the front.
