Re: ATL: INVEST 90L
We can continue the discussions in this thread until the new invest 91L is up and then we switch to that one.

Now we know it was a teaser. The real deal will be 91L.

Re: ATL: INVEST 90L
The new low center looks to form later tonight inland over the Yucatán peninsula near Campeche. A broad trough axis has formed in this area and the upward vertical motion on the east (convergent) side of the axis is intersecting an area of low- and mid-level vorticity that should become more aligned tonight. In the evening, the diurnal maximum should allow convection to develop closer to the vorticity center as the convection over the E Yucatán diminishes due to cool outflow. Low-level convergence will shift over to near Campeche as the trough axis moves through.

700-mb vorticity
The dot to the left of the "L" denotes the area where I believe the low is developing:

Re: ATL: INVEST 90L
For those who may want to know where the invests pop up and are deactivated here is the ATCF file for 2013. At the top in the deactivations section you can see 90L deactivated. 91L will pop up below the 90L one if you look down the list.

Re: ATL: INVEST 90L
I'm a little surprised that convection has persisted for nearly nine consecutive hours near Cozumel and has expanded both to the NE and to the SW. These storms are producing rain rates of up to 1.5" inches per hour! Already they are warming the upper troposphere and strengthening the anticyclone at 200 mb; note the emergence of "feathery" outflow on the NW and NE sides according to recent satellite data. None of the models has really captured the strength of the convection which we are seeing now.

My firstgraphic for this. Red is heaviest conection over last twelve hours. Yellow is where development could begin over the next three days.
Just a simple graphic for now.
Made with SketchBookExpress on my iPad.
EDIT: Unable to get imageshack to work on iPad., can't copy code. Grrr.

Re: ATL: INVEST 90L
Looking at the HR vis sat loop I can several vorticities where I marked the X on the pix below.
The vorticity in the western BOC is still pretty strong while the vorticity over the interior of the Yucatan P. seems to be getting a surface reflection.
IMO, this might be the reason why 91L has not come out yet because they are trying to wait and see which vorticity becomes the strongest to make sure they start the models right.

If you don't mind me asking, what indications? I haven't seen any.

the low level flow has turned more east to west as the ridge builds in. u can alse see a weak rotation taking shape. however there is likely to be multiple vorts develop with every burst of convection.

the low itself will likely spin up fast. the shear will be the big inhibitor for the nhc. just north of the ne tip of the yucatan penisula is where its starting develop however i am on my phone sooooo lol

Re: ATL: INVEST 90L
If the center ends up being over the Yucatan would it start weakening due to land interactions

It would be weak to begin with, not that it will weaken, and will stay weak and broad until it moves over water.
