A large but disorganized area of thunderstorms is near & east of Fl. This is primarily associated with a surface trough of low pressure.  The area will have to be monitored for persistence but at this point little or no development appears likely.

The satellite images below shows a very large area of stable air & cool temps. aloft covering much of the Central Atlantic east of the Caribbean with a remarkable lack of any showers or storms let alone tropical waves from the Caribbean far to the east across the Atlantic.  The second image below -- water vapor satellite -- shows this stable area very nicely (black & rust-colored area). Such an atmosphere is generally unfavorable for tropical development.

Dry air & shear are hammering away on most of the tropical waves moving west off of Africa.  There is, however, a stronger wave that's moved off the African coast.  Some long range forecast models try to develop this wave as it moves west across the Atlantic through the end of the month.  The wave would approximately be near the Caribbean or SW Atlantic in about a week's time or so.

Unusual for this time of active storms in the global tropics(!).
