Marine Conditions:

The Caribbean Sea

There are three tropical waves moving across the basin.

Please refer to the section above for details on the tropical wave moving across the basin.

Over the southwest Caribbean, the monsoon trough extends along 10N between 76W-83W. Scattered moderate convection is noted along the trough mainly south of 10N. Scatterometer data depicts fresh to strong trades prevailing across the south central portion of the basin south of 18N between 70W-82W, while gentle to moderate trades prevail elsewhere.

The Bermuda High north of the area combined with low pressure N Colombia will continue to support fresh to strong NE to E winds over the central Caribbean through most of the week. Expect an increase in areal coverage of strong wind speeds through Wed night, reaching as far north as Hispaniola adjacent waters. Winds near the coast of NE Colombia and the Gulf of Venezuela will pulse to near-gale force at times, through Thu morning. Fresh to strong E winds will occur in the afternoons and early evenings in the Windward Passage through midweek. Fresh to strong winds are expected to pulse in the Gulf of Honduras Wed night and Thu night. No tropical cyclone activity is expected through the week.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Tropical development is not anticipated through at least the end of this week, mainly due to a broad area of Saharan dust over much of the Atlantic basin.

There are a few waves moving westward through the basin, but none of those waves show any signs of organizing.
