The Caribbean Sea

An upper level trough passes through 22N61W in the Atlantic Ocean, to 14N66W in the Caribbean Sea. A surface trough is along 64W from 10N at the coast of Venezuela to 20N. Precipitation: Isolated moderate within 360 nm to the east of the surface trough, and within 600 nm to the west of the surface trough, in the trade wind flow. Comparatively drier air in subsidence covers the Caribbean Sea on the western side of the trough, and elsewhere from 11N northward from 87W eastward.

Broad surface low pressure covers the SW corner of the Caribbean Sea. The monsoon trough passes through Costa Rica and Panama, into northern Colombia along 75W from 08N to 09N. Satellite data and the GFS forecast for 250 mb show upper level anticyclonic wind flow in the SW corner of the Caribbean Sea. The GFS model forecasts for 500 mb and for 700 mb show NE wind flow in the same area. Precipitation: rainshowers are possible from 12N southward from 78W westward.

The wind speeds and the sea heights will diminish across the region, gradually, as high pressure in the Atlantic Ocean shifts eastward. The trade winds in the central and eastern Caribbean Sea will increase early next week. Fresh trade winds and moderate NE swell are expected in the Tropical N Atlantic Ocean during the weekend.

On Ambergris Caye this morning the breeze is from the East at 5 mph and the sea around our barrier reef is calm. We have clouds and scattered sprinkles of rain.

The Caribbean easterly winds are being slowed down against the Yucatan. It looks as if the westerly high level winds are helping cold air to move down from the north, holding back the Caribbean wind, there is even indications of this happening in north Guatamala, close to Belize. Further south, the Caribbean cloud is bunching up just off the coast with some clashing with high level winds, so I suspect a fair few rain showers just off the coast, more so off southern Belize. There is cloud covering the mountains and a fair bit of central Belize and other activity, looking like the cold north air is pushing in. There is a fairly strong "Tiger" surface wind from the SW this morning.

Looks like much of northern Belize is having sunshine but clouds will develop this morning, central is mainly cloudy, but a few patches of sunshine, southern Belize has a fair bit of sunshine, but clouds moving in from the sea. Some rain expected, particularly the south coastal areas.

There is cold air pushing down into Belize right now, the easterly Caribbean air is riding up over it. The cold air mass is slow, hence the blunt arrows. Yet, despite the direction of the two winds, the surface wind is coming in off the mountains from the SW, not shown on this map. I can't see what rain, but looks like down south and off shore rain showers.
