looks like development will now hinge on which model gets the track right.

Correct! On this loop you can clearly see it tracks thru Central America, Yucatan Peninsula and it barely emerges in the BOC... http://www.tropicaltidbits.com/analysis/models/gfs/2013080918/gfs_z850_vort_watl.html

Cycloneye, thanks for sharing this very informative blog about the models. I found this part interesting regarding the FIM model plus the SPC3 looks promising as intensity forecasts continue to be extremely challenging to forecast:
"However, the new FIM9 15-km global model was competitive with the ECMWF and GFS models for track, and the new CIRA Statistical Intensity Consensus (SPC3) model for intensity performed better than many of the traditional intensity models."

Re: Global Model Runs Discussion
GFS is definitely getting active now. I counted 5 storms on the 00Z, 3 storms on the 06Z, 3 storms on the 12Z, and 2 storms on the 18Z thru August 25th. http://mag.ncep.noaa.gov/data/gfs/00/gf ... precip.gif

It also says Utor will remain a depression
It CANNOT be used for intensity until the TC interacts with a mid-latitude system. Something likely horrible in the parameterization

Didn't the big upgrade fix that issue?

Global models continue to be quite lackluster on any development for the next 10 days at least. Only possibility at the moment would be a Western Caribbean / Yucatan / Western GOM system that develops around 5 days from now but even for that system, global models have backed off some.
The 384 hour 06Z GFS shows virtually nothing from the Cape Verde season yet except way out around 360+ hours which is suspect this far out.

12Z GFS is totally quiet through 16 days.
One thing briefly discussed in the office was that we don't have the disturbances to develop due to cold waters in the western Indian Ocean. This may be preventing the waves from forming over E Africa in the first place. I have never considered this factor
