I wasn't going to say anything but....every NOGAPS image that Ivan posts, it's never there! IMAGE

If the Nogaps image does not show up, your browser is blocking it.

If you are using IE, you should have a bar on top that you need to click in order to view.

The blob presently SW of the Cape Verde Islands looks mighty interesting to me. Judging by the title, I don't think this thread is about that but it's just too big and swirly looking to ignore IMHO:

That blob below 10 degrees is just being sustained and is part of the ITCZ, any rotation earlier was above 10N and has since dissipated. The real wave to watch is still emerging off Africa.

Would it be possible for it to break away from the ITCZ with such intense convection?

But if that blob below 10 degree's continues to fire convection an MLC could work its way to the surface, needs to be watched IMO.

Yes, if it forms a surface low/LLC.

I personally don't think so, being as the convection is sustained by the ITCZ itself. The wave emerging off Africa is actually a wave with a low pressure center and has the inner dynamics working for it. That one also is the one with model support.

It looks like it is having a fun time down there. Shear is very low(Below 10 kts) and it is probably feeding from some very warm Sea Surface Temperatures closer to the equator.

i guess its one of those eyes are deceiving me things, im sure if it was worth watching the nhc would have surely coded it by now.

This is the wave with some model support. The one about to come off the coast.

:uarrow: Yep,that is the one. The ITCZ perturbation may need a separated thread. :)

Methinks Hurricane Flora (one of the most infamous hurricanes in the history of the Atlantic) developed out of a similar ITCZ blob - albeit in September.

It's not impossible but it would be rare. I will say though looking at ASCAT, something may be going on.

The wave is also entering the CATL view and has extremely heavy convection with it..

Thunderstorm Trigger
One trigger for convergence is the meeting of the Northern and Southern Hemisphere easterly trade winds near the equator. The meeting of these wind belts triggers numerous, daily thunderstorms in a region called the Intertropical Convergence Zone (ITCZ). Occasionally, a cluster of thunderstorms will break away from the ITCZ and organize into a more unified storm system. From NASA


I think this is a area to watch.

Here is the latest on the wave emerging from West Africa. Image updates every 15 minutes.

It may or not be a product of the ITCZ but the convection has lasted a long time already

Some strong convection , something to watch anyway.
