I'd roughly agree with your position but I would put it a shade closer - the LLC is distinctly under the CDO. However, what's really impressing me is the rapid growth of the LLC, which now encompasses the entire E Caribbean. That suggests to me that it's moving more air than the decent but not fantastic central IR presention indicates.
I just don't see the LLC under the CDO. Looks like the LLC is 60-70 nm. WNW of the CDO ahead of the cirrus shield. All I've been doing is staring at that thing since 4:30 this morning. It's about impossible to see the LLC with IR imagery, though. I can't find it now, as all I can see are mid and high clouds. It does appear to be moving rather quickly, and on a track to the right of the NHC forecast. Not far from the GFDL forecast, actually.
I don't see the LLC itself: I see arcs of clouds revolving around a point toward the NW side - but under - the CDO (at least on IR2). The LLC disappeared under the CDO before the sun went down. The cloud arcs appear to the at the same level as the low-level cloud arcs that were obviously rotating around the LLC when you actually *could* see it on RBG. You can see arcs coming out of the SW side of the CDO - they certainly aren't associated with an exposed center. The center to me appears close to the 8PM forecast point on the 22:45 IR pic and that's certainly under the CDO.
