The Atlantic Basin -- remains void of any tropical activity -- full of dry air & high shear.  Weak low pressure does seem to have evolved at about 30 degrees N (Jax's latitude), 60 degrees W. but is not tropical at this point & is part of a decaying frontal boundary.  This area will need to be monitored for persistence.

A huge area of dry mid & upper level air continues from the Caribbean east for hundreds of miles across the Atlantic. Overall conditions remain unsuitable for significant tropical development as shear generally remains high too.  An upper level low is spinning -- & very noticeable on the image below -- near the Bahamas.  This system will move west the next few days but no surface development is expected.

Shear is still strong over much of the Atlantic Basin exceeding 40 knots(!) over parts of the Caribbean...exceeding 25 knots over the SW Atlantic (but diminishing overall)....& 20+ knots over the Gulf of Mexico....

Tropical waves are struggling as they move west off the coast of Africa.  Little development expected at this time with the few waves that are westbound.  Dry air is very evident on the IR satellite below - note the patchy light gray colored clouds which are stratocumulus clouds - indicative of a stable air mass.

The Pacific, on the other hand, is a far busier basin (& could be a hint of an uptick in Atlantic activity later this month).  Hurricane "Henriette" will be to the south & east of Hawaii by the weekend though far weaker....a couple of other disturbances in the E. Pacific have the potential for slow development.
