Looks like JMA shows some development thru 72 hours.

What about the waves rolling off of Africa any model support?

Well, the Euro seems to have a TD close to where the GFS forms one in 48 hours. It's the wave coming off Africa helping to spin up the current convection sitting off the coast it seems.

Yeah Euro has a vorticity in the same spot as the GFS at 96 hours ,only weaker.

Weaker this run. Ridge seems weaker also. Maybe another OTS?

Why would NHC bight GFS I mean nogaps has been horrible. Until for me personally I see real decent support from the ECMWF sorry I don't by it.

Move along till 2018.. lol. I don't even think this massive mjo or kelvin wave will help. GFS will likely drop new phantom tc soon.

I want to believe that the switch is finally being flipped on, but until the ECMWF shows it too it is hard to believe. Looking forward to seeing what the EPS says.

Screw the ECMWF and use your own eyes IMHO. I don't really care what it says, because it's unreliable in the long term. This may be its worst year I've ever seen it. Same goes for the GFS which does now show a couple of developments, including 99L. That only took about 10 days. It has a recurve a week later from the low just off Africa. CMC looks more believable and does take a system toward SFL at the 10 day period. GFS shows a ripple down there, so it does follow along the wave.

Also QPF seems to be having the worst year that I've ever witnessed. I don't know if this is primarily due to the upgraded GFS, but it underestimates the 7 day precip totals week after week after week after week. For instance, consider the 7 day 12z which came out early this morning.

South Central Louisiana has more than double that in less than 1/2 of a day vs. the entire 7 day period. Global models and corresponding contributions to various product outputs are becoming trash for whatever reason.

Agree ,looking at the system off Africa it shows potential. Also 99L looks poised to develop and that really has little model support

12Z runs of GFS, CMC, and NAVGEM all have this already initialized at about 10N 30W and all are developing it.

What I can tell from COAMPS is that it will maintain as a moderate wave and track west into the Carib at this point.
