Hopefully this African Wave will change my mind about this season being a dud.

That should take care of any surface features.

Oh, good news. Now we'll have to see whether the GFS still shows this on the 18Z run.

The system continues to look rather impressive on water vapor and visible imagery, and is showing signs of weak convective consolidation and organization slowly occurring due to favorable middle to upper-level divergence, weak diffluence, and weaker shear. Mid-level drier air has continued to gradually mix out as well, with low latitude and convergence continuing to slowly help in convective bursts and maintenance, as evidenced in the imagery shown. As a possible MLC may reform, the system may be a fair candidate for our next INVEST and may be declared a wave/possible weak low by tomorrow or in coming days.

In addition to the synoptics mentioned, weak anticyclonic flow and divergence established may also aid in gradual development.

It just looks like a blob wave to me. Should rather wait before anyone gets too excited about it.

True; however, compared to earlier waves, overall middle to upper-level flow is more favorable and may prove to be so over and ahead of the wave. Due to this, as well as the other favorable synoptics mentioned (including lower latitude and less mid-level drier air and SAL intrusion), slow development may be aided. Convection, consequently, has also continued to maintain itself after leaving the coastline now.

Big difference here is Tstorms are developing not diminishing..

difference now is that it is the end of August, so chances keep going up for development out there - it looks good to me and it is south enough to have the warmer SSTs to work with...

I'm liking this wave.

In addition, several waves in past years under similar synoptics this time of year that have spawned named systems were very similar to this system in terms of general convective maintenance and surrounding synoptics. I believe Frances (2004) is a somewhat good example, as well as several others. ITCZ proximity may help, too.

The 06 Z and 18 Z are not the best GFS models to look at since it contains limited data. I would stick with the 12 Z and 00 Z and look for trends.

Looking at the low latitude the area is now it sends me flashbacks about when Georges was developing that far south.And the rest is history.

Man Luis!!! You got me all excited LOL. I didn't notice the date and my eyes zoomed immediately to the "tropical depression has formed" lol... and then I felt the excitement quickly vanish when I saw the date... :lol:

ConvergenceZone,that is why I posted a sentence above the advisory to let know all it is about Georges. :)
