Low Level Circulation??

Its a blob to watch. Whereas we have had nothing to watch in the atlantic for a week and 1/2 now.

There is always the chance for a LLC to develop.

Yes Ticka, watching blobs are how tropical weather fanatics stay sane during the slow times 8-)

wxman57 great graphic you made there!

Thanks for sharing it and thanks for the explanation

Tick, Im with ya on that one... every tropics nut needs his fixin of blob watching :o ...

Not surprising since it's located in a region of strong shear driven by both the upper low and the mid latitude trough to the north. Although the ULL will crap out within the next day or so, the shear pattern probably won't become any better. Might I add the disturbance in the EPAC and the trough will serve as moisture robbers. In other words...this is a no show.

just one question why always and EPAC system would serve as moisture robber?? why not the other way?? just want to know !

thanks in advance!

Great graphic, wxman57... helps a lot.

I could never make something like that... :lol:

Yes, great graphic, wxman57.

I was looking at satellite loops last night of the western Caribbean and I saw south to north moving clouds to the east of north to south moving clouds to the southwest of Florida, northwest of Cuba.

The upper low is still generating way too much upper level shear. The only window of oppurunity will come once the wave makes it into the Gulf before the trough moves in.

I noticed that the upper level wind shear has been on the decrease over the eastern Gulf of Mexico, once again... prior to the to the trough moving in.

<i>There was clearly a LLC over NE Honduras yesterday which has drifted NW overnight. Visible satellite imagery picks these up better than a quicscat run. quickscat doesn't have enough definition to pick up small low level cloudcirculations over land. I trust my eyes mote than quikscat. That being said, until we get a good look at visible loops today, we won't be able to determine whether it is still there, although a slight turning in the convection to the east suggests it may be. Let's see what today brings.</i>

Not the most scientific approach, but that's OK. QS does have its problems with small LLC's near land; however, if there is not even a significant wind shift, there is nothing. No obs showed a west wind; thus, what you probably saw was an MLC and not a LLC. There is still yet to be a LLC, but there is low level divergence as indicated by the outflow boundaries, not good for development and none is expected anytime soon as a result

So there is low level and upper level divergence in the northwestern Caribbean?

I haven't seen negative upper level divergence values in the last 24 hours.

Low Level Circulation??
