Quote: Could someone look at the Carib sat and tell me if that is a low pressure rolling up the NE coast of South America towards the Caribbean, and explain the significance?
Hi Margie... It is indeed a closed-circulation...of what?? It's got all the halmarks of an upper level cold core low, in that these granular showery patterns are loosely strewn about it's axis, and, as I've been watching them occasionally today, they seemed to increase with diurnal heating. The other thing, the visible imagery shows almost a flat non-eventful trade wind in the llv's, also as is usually the look when we have a lower latitude cool core features.
The only trouble is, what was the origin?? I'm perplexed with that, because I watched this feature come from the deeper tropics - no if-and-or-buts about that and in fact, it was previously associated with a very deep convection in the cenral Atlantic near 10N Wow, ay? That I'm aware, NHC hasn't given any mention to it so we can assume they must know but don't see it as even interesting enough to mention? I think it is just fascinating anyway. The thing is, there is an interesting looking wave ENE of there...
