Please remember in the early stages of Tropical Storm development what generally happens and is not at all unusual is the formation of a broad area of low pressure and very small areas of low pressure within it. As thunderstorms fire these baby lows shift around and generally will line up with the most intensive areas of convection. At this stage it is quite common to see this huge mass of convection and we have to remember that it is only now that the shear in the upper environment has weakened enough for development; for most of the week there has been a band of westerlies from the Yucatan across Cuba and into the Atlantic bending ever so slightly east-southeast making it impossible for anything to get ginned up. We also have to remember in the Eastern Pacific, there's Hurricane Darby and in the 2am PT discussion this morning how this wave in the Caribbean develops will have a direct impact on the future course of Darby. I would encourage all to read that discussion courtesy of the NHC.
