The gfs shows a recurve
http://moe.met.fsu.edu/cgi-bin/gfstc2.c ... hour=168hr
however, it also shows a positive NAO and a building high in the nw atlantic. this may still be a threat.

Some GFS ensembles are suggesting a possible risk to the NE Caribbean. I also can't get past the fact that the GFS was orginally recurving Issac around 50W...

The first Bams run is not out yet. Let's see how the tracks and intensity will be when it comes out.

Re: ATL: INVEST 98L - Models
Think the models are assuming a stronger system? Looks like it's just going to churn along in the low level flow for a few days.

Re: ATL: INVEST 98L - Models
Given the setup this year i am not yet convinced this is a recurve. Take a look below at what the models were showing with future Issac early on. Looks similar as the models tried to ramp this up in a strong system and we all know that it stayed weak.

Well models are pretty keen to recurve this, but I'm not sure they are getting a good grasp of this system and the models appear to start this one too far north.
Kirk could well make things interesting, especially if it does become stronger.

Thats a very agressive run from the SHIPS cycloneye!
We will have to see where this eventually ends up, most models are real keen on a recurve but we've seen this before with Issac...

I think rainstorm its going to depend on how qiuckly this one gets going, if its ramping up before say 40W, I can only see a recurve as a nice big upper trough is starting to dig down by say 96-120hrs, assisted by both Kirk AND Issac's remains, if it stays weak though then it may just bypass any weakness and wait for the next one to lift up throug the Caribbean.
Either way I do think this will become the next decent system.

I don't buy the GFS solution right now one on one key point. It leaves behind a portion of Kirk as it connects with the jet. I think it will stay as one low and exit N and E. It looks like Kirk is a little too slow getting out. Also the Bams (M and S) have a curiuous bend NW at the very end of thier runs after the hard right turns.
I think the ridge will be stronger than that and the recurve, if it actually happens will be much further west.

Re: ATL: INVEST 98L - Models
Way too early to say if there will be a recurve yet, especially since the recurve portrayed in the models is in the 5+ day timeframe, where we have very little skill. I haven't looked at the actual statistics for storms forming in the general area of 98L for this time of year, but I would bet that they show a greater likelihood of recurvature over open ocean than not.
In any case, most of the numerical guidance has been aggressive in developing this system, so I say it has a good chance of becoming a named storm. Hopefully it will be a nice major that bothers nobody but the fishes!

Re: ATL: INVEST 98L - Models
Well if what systems have done so far crossing the atlantic are any indication this probably wont develop until it gets close to caribbean if at all

agree...Kirk needs to get out of the way and let that weakness fill for this to have a chance.....if it developes sooner then it would just follow Kirk out....
