the models are not handling anything well right now.. the BOC is not getting any stronger really and if IDa continues to strengthen then the BOC low will have less of an effect on IDA. The trough should begin to move both of them and depending on IDA strength and the strength of that low will depend on if they merge and we get this transitioning system or not.

Ita really interesting how these models are still having monster systems even in the central-north GOM but I'd be shocked if we saw anything as strong as HWRF has up there.

Yep 70mph as others have noted looks about right, pretty interesting system this one is, really think this one is heading for hurricane status soon, may have a hard time getting above 80kts however IMO, remins me a lot of Irene at the moment.

Just wanted to comment that it seems like the SFMR might be having a slight problem in that most recent set of HDOB data...either that, or there's a massive low-level inversion in the storm that's preventing the stronger winds from mixing down, and that's quite unlikely.

pressure under 990 now.. recon almost to center with winds of 33kts and 988 pressure.. so center fix should come back with around 986 987 or so ..

Ummm, no. The white is the next colder cloud tops after the yellow color, not a clear spot. Just a very tall/cold thunderstorm, not an eye.

Considering earlier the winds were in the 50's on the SFMR. Also, pressure is down into the 988's right now (still away from the center)

We're about to have a hurricane on our hands it seems. I'm worried about a strong extratropical storm impacting the gulf coast, could be a significant wind and flooding event.

possibly while in the carribean.. once in the gulf things get tricky and maintaining that will be hard unless its moving faster..

Re: ATL : TROPICAL STORM IDA - Models

#1817 Postby Blown Away » Sat Nov 07, 2009 1:37 pm

12Z: Ukmet, CMC, GFDL, HWRF, and GFS all swing Ida or the remains of Ida back through the Florida peninsula. These models also rapidly move the system near or onto the N Gulf Coast in about 72 hours. Ida better pick up some forward speed for those models to verify if not I think the ENE turn could happen farther S in the GOM.

if the center is where the recon has located it, there seems to be some mlc to the northeast, maybe the storm is tilted

looks like an escape route out to the NE/ENE looking at the 00Z NAM H5 flow. Now that she is much stronger than any of the models initialize her to be you wonder. She may be "eyeing" that

She's also more north of where the NAM has the X. That H5 ridge is still over Texas/LA here and has not got to her yet. Thoughts? Obviously a weaker system wouldn't feel that weakness to the ENE. Would follow climo if she hits that weakness.
