Re: ATL: INVEST 99L - Discussion
Cayo Coco now reporting NNW winds, very interesting. Showing me that the circulation might be relocating to the NE of that Key closer to the deep convection. IMO.

Re: ATL: INVEST 99L - Discussion
I am not saying this is Tropical Storm Issac, but 99L is almost in the exact same position.
And really if 99L does decide to form, that track cannot be ruled out. GFS ensemble keeps flip-flopping, really all the models been back and forth and there are some ECMWF ensembles that have that path.

Re: ATL: INVEST 99L - Discussion
Circulation with 99L is beginning to turn a lot more atmosphere than any other time. Inflow from the west is very noticeable. Look south into the Central Caribbean as well and notice all the thunderstorms moving in from the southeast. Pretty interesting.

Re: ATL: INVEST 99L - Discussion
Still an active entity I would say to be watched in the Gulf. Especially if it turns north. May even have a S component right now.

It looks like it's going to move into Cuba which will disrupt any progress it's made.

Re: ATL: INVEST 99L - Discussion
I was just noticing the BAM Medium, Shallow and Deep all have a similar track.
So the HWRF is apparently creating the poleward motion from rapid intensification.
Often when the BAM models line up it idicates low shear.

The 1-min visible is fun to watch this morning. Seeing some more convection developing in the red circle. Lots of work to do though.

Re: ATL: INVEST 99L - Discussion

Shear has increased right near and over the area where 99L is located. Very small increase though.

Re: ATL: INVEST 99L - Discussion
Is this broad area of circulation trying to collaborate further back east a tad?
Would make sense with the NNW wind at Cayo Coco

Looks to me looking at Visible that the LLC is moving west and will miss Cuba. I could be wrong but what I see currently. It is also becoming much better defined and not so naked.

The sheer maps have obviously been pretty bad.
I would not even look at them. Focus on real-time data

In the NE quad at least but the LLC and most of the convection is still under the green.

Still looks WNW to me and paralleling the Cuban coast, the LL swirl is as vigorous as it has ever been...
