Since it's already been said about pressures falling in the caribbean it appears that a high is trying to build overhead the NW Caribbean as indicated by the cloud field taking on a more circular appearance. Secondly, the area E of the Bahamas seems to be organising and deep convection is on the increase. Given the proximity of the areas to each other I do not believe that both could develop. If the Bahamas gets going first it will increase shear over the NW Caribbean and inhibit any chance of development there unless it heads off to the NE very quickly. The next 12 to 18 hrs will be interesting to watch especially as surface pressures in the NW Caribbean are relatively low ( 1010.5 here and 1009 to our South at the buoy ). What is any Mets or borad readers take on this scenario?
