Marine Conditions:

The Caribbean Sea

The pressure gradient between the Bermuda-Azores High located well northeast of the area and the Colombian Low supports fresh to strong northeast to east trade winds across much of the central Caribbean. A 1017 mb high is along the western tip of Cuba.

Seas are in the 8-9 ft range with these winds based on overnight altimeter data passes. Mainly moderate trade winds along with seas of 5-7 ft are in the eastern Caribbean, while gentle northeast to east winds are over the northwestern Caribbean along with seas of 3-5 ft.

An elongated upper-level low is identified on water vapor imagery to be over the northwestern Caribbean near 21N86W. It continues to support the development of showers and thunderstorms across parts of Cuba and the NW Bahamas and convection associated to the tropical wave along 82W as described above. This feature will also continue to aid in the development of showers and thunderstorms over South Florida today. The upper-level low will move into the far south-central Gulf of Mexico by early this evening.

For the forecast, strong high pressure centered over the north- central Atlantic extending a ridge to the northern Caribbean will maintain moderate to fresh trade winds across the E basin, and fresh to strong winds in the central and portions of the SW basin through Fri night. These winds will be modulated by a pair of tropical waves moving across the area. Gentle to moderate winds in the northwestern Caribbean will increase to moderate to fresh on Tue, and reach strong speeds in the Gulf of Honduras on Tue night, continuing through Fri night.

A large dust cloud from the Sahara is heading towards the Caribbean region where it would be occurring over the next few days.

The National Hurricane Center is painting the northern Gulf as an area to watch for quick tropical development toward the end of the week. The odds of something organizing look low right now, but ingredients are forecast to come together that sometimes result in a tropical system spinning up.

We are in a rather strange, and complex weather situation, we have mid-high level air and cloud coming down fast from the north, from the US and at the same time, ITCS activity over Honduras and other causes, is sending high level cloud up fast over Cuba, so we have a high speed, large gyro over the Caribbean and turning tightly over southern Belize. To make it more difficult,NOAA are having problems with their satellite images, so the best I have been able to capture is 06:50 this morning. But it is all causing a fair amount of rain across parts of Belize this morning. And yet the ESE Caribbean winds over Belize are normal.

Looks as if today is going to be very variable, sunshine, cloud, heavy cloud and rain, more so in central and south.
