A rather large upper level low is over S. Fl., the Fl. Straits & Bahamas.  This upper level feature will move slowly west/northwest but with no surface development expected.

Lots of convection across S. Fl. in association with the upper low as can be seen below (radar imagery courtesy S. Fl. Water Management District):

A weak tropical wave is approaching the Lesser Antilles/Eastern Caribbean.  This wave came off the coast of Africa late last week & has been slowly moving west.  Convection has increased some but models are not enthusiastic regarding development.  The water vapor image below gives us a hint as to why: a good deal of dry air is over the Central & SW Atlantic along with pockets of significant shear.  If the wave becomes something to reckon with, it would be in the long term over the Western Caribbean or Gulf.  

Meanwhile....tropical waves moving off of Africa are weak & showing no signs strengthening.
