The Caribbean Sea

There is one tropical wave in the Atlantic, and two in the Caribbean. Aside from the convection discussed in the Tropical Waves section, isolated showers and thunderstorms dot the waters north of 19N between the Windward Passage and Yucatan Channel. The rest of the basin enjoys tranquil weather conditions. A weak pressure gradient supports moderate or weaker easterly trade winds across the basin, except for locally fresh to strong trades off N Colombia and the Gulf of Venezuela, with fresh to local strong winds in the Gulf of Honduras. Seas are in the 3-5 ft range in the south- central Caribbean as well as in the Gulf of Honduras. Seas of 1-3 ft prevail elsewhere.

For the forecast, the two tropical waves in the western Caribbean are expected to continue generating strong thunderstorms across NE portions of Honduras and Nicaragua and across the Gulf of Honduras. This active weather is expected to shift gradually westward with the tropical waves through Wed night. Weak 1015 mb high pressure is centered near 25N70W and yielding generally moderate trade winds across much of the basin. This high will strengthen modestly behind the exiting tropical waves tonight through Fri night to gradually bring a return of fresh to strong trade winds across the south-central basin. A tropical wave accompanied by a very broad surface trough will move across the Tropical Atlantic waters Thu night, across the eastern Caribbean Fri, and the central Caribbean Fri night and Sat.

The tropical wave that is advancing over Nicaragua and Honduras has a 20% chance of cyclonic development for 5 days. This tropical wave is expected to continue moving over Central America, emerging in the Bay of Campeche where it is possible there is a gradual development of this system and a center of low pressure would be forming near the weekend as it moves northwest. At the moment it is not possible to determine a trajectory or impact of this system as nothing is formed yet.

That storm over eastern Honduras has moved up into the Caribbean and producing many small swellups, most out at sea, but some now over northern Belize and coastal central areas, so rain, some heavy.

Looks as if today will be rather cloudy for most and rain in the north and some central areas.
