In the loop it looks like the light of a thunderstorm was captured in the picture. Looks kind of cool.

I'm not sure to be honest. I should note despite what I feel about what the system looks like now I still wouldn't be at all surprised if it does develop into a cyclone of some sorts (be it TD or higher!) but I think the SHIPS are on the agressive side. IF we see better convection overnight then I will be far more interested.
Still its got a good circulation I'll admit that and the southern half of the system is starting to look better...I reckon we could have a TD tomorrow from this...

Big change has occurred throughout the day. As upper level shear decreases, an excellent environment of divergence is presented. Low level vorticity is also decent, and low level convergence is increasing. Overall, we may see a TD by tomorrow, though I don't expect significant intensification beyond a weak system.

It certainly is looking better and better, I think my post about an hour ago was probably a little harsh on the system presentation, the southern side is clearly sucking in moisture from the ITCZ and is probably strengthening right at this min. If it carries on like this it may be a matter of when and not if it gets upgraded.

Re: EPAC: Invest 90E - Near Central America
I would be surprised if 90E becomes a TD tomorrow. Conditions appear only marginal for a TC to form. Convection is limited to the south of the circulation center, there is some moderate shear to the north. In fact, it appears that an ULL is trying to close off over Guatamala this evening. If that is the case than forget it. I'd say there is only a 10% probility of development at this time......MGC
