I know that the NHC is experimenting with a 7-day forecast track internally this year (and for the next few years). I'll bet they are running the models out to 7 days to assist them in their internal 7-day tracks. No sign of the GFDL/HWRF being run 7 days yet, though.


That is good to know about that extension. I didn't noticed until I read your post. :)

They've been sharing them with HPC because on several occasions I've seen the HPC referring to 6 and 7-day positions from TPC/NHC in their discussions.

Thats very interesting indeed!

Thats the first time I've noticed this on the BAMs though, the previous runs only went out to 5 days but it seems like they've updated those runs and now put it out to day-7.

Anyway 12z GFS on its way out now...

12z GFS out to 108hrs:

Heading near due west upto this point along 15N but I'd imagine with a bit of strengthening it'd start to lift out WNW.

Yeah 12z heading into Yucatan and probably into the BoC...that being said I wouldn't be all that surprised if the system ends up to the north of where the GFS is expecting as the model keeps it very weak till the W.Caribbean.

The GFS effectivly pulls an Iris, the system heads west then WNW and before the Yucatan actually starts to bend back slightly WSW a little as the upper high builds in as it makes landfall....

The BIG difference is the models suggest enough of a tug from the north to lift it back WNW/NW over the Yucatan and towards the BoC...looks like a Mexico run this time round.

I would be shocked if this isn't a Yucatan and then Mexican threat. What else would it be in 2010 if it can't recurve? lol

The 12z GFS slows this one right down in the BoC but does eventually make landfall in Central Mexico.

I would be shocked if it's a Mexico storm, due to all of the ones we've already had that have went to Mexico...Luck has to run out sooner or later.

You'd be shocked if the model was wrong 8 days out? Well, I suggest you prepare to be shocked.
