The Tropical Weather Discussion for the Caribbean Sea from the National Hurricane Center is below.

Caribbean Sea
The Caribbean remains quiet with plenty of dry/stable air. The mid-upper level pattern producing this stable environment consists of an upper ridge centered in the western Caribbean near 17N83W and slight ridging east of the area in the tropical Atlantic.
A weakness is above the central Caribbean induced by a weakening trough to the north/northeast. The only area of significant weather is in the extreme southwest Caribbean where scattered moderate convection is south of 11N between 76W-82W.
Overall, little change is expected as dry air remains established across the area. Trade winds are moderate and will likely remain that way. The areasof the Caribbean mentioned are the only ones of note. The majority of the Caribbean is dry.
