Is the blob of energy that is firing up at 35W/10N with convection something we need to start paying attention to? Just noticed that the convection is really starting to take shape and it appears this system may have possibilities. Just an observation that I noticed but I could be way off.

Chris, you are not way off at all. This is the time of year where every blob is a suspect. The area in question is part of a tropical wave. The blow-up of convection could lead to a LOW developing. The latest plot from TAFB for tomorrow shows a low pressure center forming along that wave. If the convection continues to increase the NHC will tag it as a Invest. Here's the map for tomorrow from TAFB/NHC.

What's the critiera for a blob to be declared an invest? The area Chris reffered to has a nice concentrated area of convection, a little spin and no wind shear. Maybe I just answered my own question!

Yep, you answered most of it yourself, plus the NHC likes to see persistence of about 12 hours, the presence of an actual LOW, and detachment from the ITCZ.

Regarding the ITCZ... Chris system is at 10 degree north latitude. At what latitude is a system considered detached from the ITCZ? And doesn't depend on the time of year? Being August, is 10 degree north enough to be considered free of of the ITCZ?
