A large well-defined tropical wave, currently passing through the northeast Caribbean Sea, has some potential for slow development over the next couple of days as the system moves to the west northwest. The system is in an area of light northeasterly shear which is forecast to weaken and move westward with the system. SST in the area is about 28C. I'd expect that the west northwest movement will eventually become more northwesterly on Monday. The wave is in an area that is usually favorable for development at this time of the season.
