Special Features

Gulf of America Gale Warning: A cold front has exited the basin this afternoon. It its wake, strong high pressure building southward into the region is prompting gales of up to 45 off offshore Veracruz, Mexico, with seas of up to 19 ft. Gale force winds and very rough seas will persist over the western Bay of Campeche through this evening. Winds will subside overnight into Wed, but rough seas will continue into Wed evening.

Central Atlantic Significant Swell: A cold front extending from a storm-force low north of the area, enters the discussion waters near 31N29W and extends to 20N55W, where it becomes a stationary front that extends west to N of Puerto Rico. Large N swell generated from this system is producing very rough seas greater than 12 ft over the forecast waters north of 22N between 31W and 53W. These very rough seas will shift eastward while gradually subsiding from south to north through late week. Rough seas greater than 8 ft cover the waters N of 15N between 26W and 63W.

Monsoon Trough Itcz

The monsoon trough reaches the Atlantic near 09N13W and continues to 06N16W. The ITCZ extends from 06N16W to 03N30W to 01N50W. Scattered moderate convection is within 100 nm of the ITCZ/monsoon trough from 03N to 07N between 13W and 38W.

Gulf Of America

Please read the Special Features section above regarding a gale warning in the SW Gulf of America.

A strong cold front has exited the basin this afternoon, leaving fresh to strong winds in its wake basin-wide. Rough seas dominate waters S of 28N, with moderate seas to the north.

For the forecast, winds will diminish from north to south through Wed morning. High pressure is expected to build over the basin on Wed, supporting moderate or weaker winds and slight seas region-wide through Thu. Looking ahead, fresh W to SW winds may develop over the northern Gulf by late week, ahead of a low pressure system moving across the southern United States.

Caribbean Sea

A strong cold front has entered the Yucatan Channel this afternoon. Behind the front, strong N winds and rough seas are developing. Fresh to strong winds and seas of 6-8 ft prevail over the south central Caribbean. Moderate to fresh winds, and seas of 4-7 ft are in the north central and eastern Caribbean. Elsewhere winds are moderate or weaker with moderate seas.

For the forecast, fresh to locally strong E winds will pulse in the south-central Caribbean into early Thu as low pressure prevails over northern Colombia. Locally rough seas will be possible offshore of northern Colombia into early Wed. Elsewhere, a cold front moving into the northwestern Caribbean will support fresh to locally strong N winds and rough seas in the wake of the front, from the Yucatan Channel through the northwestern basin through Wed. Following the front, high pressure will build over the Gulf of America, leading to moderate to fresh N to NE winds over the central and western Caribbean through late week. Over the Atlantic waters, rough seas in N swell will prevail through late Thu, with seas subsiding by Fri.

Atlantic Ocean

See the Special Features section above for information on significant swell causing very rough seas in the central Atlantic.

A cold front extends from 31N29W to 20N55W. E of the front to 25W, and N of 28W, scattered moderate convection and fresh to locally strong SW winds are ongoing. Behind the front to 45W, and N of 29N, fresh W to NW winds are ongoing. Another cold front extends from Bermuda through the central Bahamas and into Western Cuba. N of 25W, along and within 200 nm ahead of the front, fresh to locally strong SW winds and rough seas prevail. Behind the front, fresh NE winds and seas of 6 to 8 ft dominate. In the deep tropics, S of 15N, moderate to fresh trades and seas of 6 to 8 ft are present. Elsewhere, winds and seas are moderate or less.

For the forecast west of 55W, rough seas in N to NW swell associated with a cold front in the central tropical Atlantic, east of 64W, will slowly subside from west to east by early Wed. A cold front extending from 31N66W southwestward through the central Bahamas and northwestern Cuba will progress eastward through midweek, supporting fresh to locally strong SW winds and rough seas ahead of the front, generally north of 26N, through Thu. Moderate to fresh NW winds and rough seas in NW swell are expected in the wake of the front into Wed. Looking ahead, fresh to locally strong W winds and rough seas may develop off the coast of northern Florida on Thu as a cold front passes north of the waters. Otherwise, weak high pressure building over the western tropical Atlantic will support moderate or weaker winds and moderate seas over the rest of the waters for late week.
