The next storm has formed across the central Atlantic Ocean, about 500 miles to the east of the Windward Islands. It is Tropical Depression Eleven and forecast to weaken before it reaches the Caribbean Sea.
The tropical depression is surrounded by dry air and the storm is forecast to encounter disruptive winds -known as wind shear- as it nears the Caribbean. Both factors are expected to weaken the storm as it approaches the islands.
Usually the forecast cone for a new storm goes out to five days, that *would* be Wednesday with this storm. However with Tropical Depression Eleven, the forecast cone only goes out two days to Sunday. That shows the storm is expected to weaken. The same weakening happened to Isaac a couple weeks ago as wind shear tore apart and weakened that particular storm. Still though, monitor the progress of this system because it will likely still bring heavy on-and-off showers to the Eastern Caribbean islands Sunday into Monday.
