Latest On Possible Tropical Development off Southeast Coast

Talked yesterday about two disturbed areas in the Caribbean with one being near Puerto Rico and another in the Bahamas. This afternoon the focus is mainly in the Bahamas northward to the Southeast Coastal region. Reviewing satellite data, the disturbance that was near Puerto Rico yesterday has been sheared apart by northward moving winds on the west side of a "Bermuda High".

This has allowed additional moisture to stream northward and feed into the Bahamian disturbance. However, the overall disturbance remains unorganized and is just a broad area of showers and t-storms from the northern Bahamas northward across the Gulf Stream off the Southeast Coast. At the same time an approaching upper level disturbance across the Southeastern U.S. will likely merge with the energy streaming northward through the Bahamas. It is possible that a surface low could develop off the Carolina coast tonight and develop into a Tropical Depression but I am not convinced. Overall, things will stay quiet relative to actual tropical cyclone development in the Atlantic Basin through the end of the week.
