The next weather system with some potential development lies in the far Eastern Atlantic where it seems the action wants to be so far this hurricane season. Conditions in the Tropical Atlantic are forecast to become more conducive for development. At the moment there are issues across the Atlantic that pose questions. First off as the water vapor imagery indicates there is a large area of dry air from about 40 degrees west to the the Eastern Caribbean. This was part of a large area of Saharan dust that moved off the African coast last week and wound up bringing about the demise of Tropical Depression 4. That area of dry air seems to be shrinking a bit but it is still rather large and this could impede development.
We also have a strong upper low sitting to the northeast of the Leeward Islands which is producing strong winds shear conditions. This is still impacting the old tropical depression 4 which is basically an open wave northeast of Puerto Rico and showing little movement. Wind shear conditions are forecast to relax across the Atlantic over the next several days.
