TD14-E may be on the horizon too...will Lorenzo play a role in all this by feeding moisture or shear?

No TD14-E yet (that would be confusing to have declared TD14's in both the Atlantic and EPAC at the same time)

I'm pretty sure this is at least a TD now. A huge burst of deep convection growing larger each hour. What's the reason for no upgrade?
