12Z and 18Z GFS have started to suggest that the African wave train should start rolling by the start of July, with a couple of possible invests come that time.

I saw this yesterday on the visible sat loop and thought it looked interesting, apparently the NHC thought so too! Today it has a 10% chance of development (not an invest yet).

QUOTE(Doorman @ Jul 24 2012, 09:09 PM) slow season straw grasping? you betcha!!!! dm Who was straw grasping here? Quite obvious the Atlantic is having a very hard time getting its act together, taking us until at least August 3-10 at the earliest IMO for the first Cape Verde activity since June, if not later than that. There could still be something small that pops up before that, such as maybe that tropical disturbance in the open ocean which I'm not too sure about.
