Circulation

[TS Zack]

In the disturbed area in the NW Caribbean their looks to be somewhat of a circulation around 81W 19N. Anybody else see this. Mainly on the Visible Loop.

It does look like one

go there

you can kinda see some spinning towards the end.

You might have to type in the link to see it since its not working when u click on it.

Looks like some high cirrus outflow rotating the other direction as if a high pressure dome is building over it as well?

[TropicalWXJustin]

There are currently what appears to be two circulations. One in the big blob and a little vortex in the line of convection to the south of the blob. The main blob circulation is probaly a MLC and this thing needs to be watched closely. High Pressure is buliding over it with the upper low ehanceing convection. Overall the enivroment is favorable for development we just have to hope that that upper low doesn't get to close to disrupt it.

It appears to me more of a mid level circulation.

Looking at the latest visible loops you can see that there is spinning going on down there. The question is will this thing hold together. If it can blow up more like it did last night, we might have something to look at for a brief period of time before it makes landfall in a few more days.

[TropicalWXJustin]

The latest TWO really doesn't give this a chance. I disagree with the hurricane center on this one. Conditions are favorable and its moving nowhere fast, needs to be watched closely.

I don't see anything but a mid level circ. nothing at the surface with the slight exception of a very very loose spin near the western tip of Cuba and the Yucatan pen.

Certainly nothing at the surface. We're looking at another convective hot spot on the southeast side of an upper-level low. The low was over the Bahamas, now it's moving SW to near western Cuba. Convection will follow it southwestward over the Yucatan tomorrow and Monday then possibly emerge into the Bay of Campeche on Tuesday. But there won't be much of an upper-low by Tuesday, so there may not be much convection either.

[Stormchaser16]

Its just hitting another hot spot like wxman has stated, this is unfavorable for development but favorable for convection. It may look nice, but like last time, I dont think theres much of a chance.

[rbaker]

yes, on the geostationary vis sat, there is a weak mlc on the southern end of convection, just about due west of cayman. However, convection is dying down, like it has before on the history of this system. It certainly isn't moving fast, pressures are running 1011-1013 mb in the region (anyone know where to get Roatan pressure?). ull going through the staits is filling in as it moves west, but certainly not the ull that was bugging this one over futher east a few days ago. Once the ull gets by and convection fires, we could once again have something on our hands.

A nice swirl around 83W 18N.. Clearly seen on visible loop. The Center!

[lilbump3000]

There is a swirl there, but we need some more thunderstorms to develop. The thunderstorms are leaving quickly.
