The Caribbean Sea

Fresh to strong NE to E tradewinds prevail across the south- central and SW Caribbean Sea due to surface ridging across the Atlantic subtropical waters. Earlier ASCAT scatterometer data showed moderate to locally fresh trade winds in the E basin and gentle to moderate winds in the NW Caribbean. Seas are in the 5 to 7 ft range in the eastern half of the basin, 7 to 10 ft in the south-central and SW Caribbean, and 2 to ft in the north- central and NW Caribbean. Scattered thunderstorms are near and in the Yucatan Channel. Scattered showers are elsewhere in the NW Caribbean west of 85W.

For the forecast, surface ridging north of the region will maintain fresh to strong NE to E tradewinds across the central and SW Caribbean Sea through at least Thu night. Moderate to locally fresh winds will prevail in the E Caribbean with gentle to moderate winds in the W Caribbean. Large, long-period N to NE swell will continue to move into the tropical Atlantic and through the Anegada Passage into the northeast Caribbean for the next several days. A cold front will dissipate as it toward the Yucatan Channel tonight into Mon.

There is significant high level clouds from the SW this morning, but the easterly Caribbean winds with cloud are a bit mixed up, presumably due to mid-level cloud out over the sea and on land this morning, causing significant rain in many places.

Looks as if today will be mainly cloudy, some sunshine, but a high chance of rain, a few heavy patches.

There are a few rain areas around, some heavy rain. There is something coming down from the north, probably some mid-level cloud, aggravating the other cloud areas, high level from the SW on top of the easterly Caribbean winds.
