Swirl South of TX-LA Line

SueOrleans · #1 Postby **SueOrleans** » Mon Sep 28, 2015 2:20 pm

So there's this swirl visible on satellite south of the Texas-Louisiana state line. Not a lot of moisture right now. I'm wondering if someone more experience than I can shed some light on it for me - why isn't it grabbing up more Gulf moisture? if I were on a boat in that storm, what would I observe? When it moves onto land, will the wind die down and fade away? As you can tell, I don't know much, but for some reason, I find that little swirl interesting. Wouldn't have noticed it at all if not for 99L over by Florida.

Here's a link: http://www.goes.noaa.gov/HURRLOOPS/gulfvs.html

Thanks!

Pressures are fairly low in that area.

It seems that this area is becoming the dominant feature in the GOM. Definitely robbing energy from 99L imo.

Wasn't this the ULL arhat was over Texas several days ago?

Yes I think it is the same area

Is that the feature responsible for all the shear across the GOM? It is what is keeping anything from stacking at the lower levels, such as we are seeing with 99L.

Yes I believe so.

HGX radar shows the deep layer low just off the coast. Cool little feature with a nice surface reflection, but there's just not enough time/space for the latent heat release needed to have the low become a warm core tropical system.

really confused why this isnt tagged. its a very strong surface low with a deep burst of convection over center ever few hours, spiral banding too on north side. Although there very strong ULL near and over it. the surface vortex is pretty darn amazing if you ask me.

It appears stationary right now just off the coast for the time being.

Phase analysis still has it weakly baroclinic.

So why is this not getting more attention? It is def looking better than 99L ever did!

I haven't seen it really progged to do anything but sink off SE toward the central Gulf and probably be absorbed by the next front coming down or peter out. NAM Hi-Res Simulated Radar shows nicely what may happen with this over at the NCEP Model site. I'm not making a forecast here, really just commenting, however, this is not to be taken as official information and is just a write-up on what NAM thinks will happen.

At one point a day or so ago one of the Models showed it becoming a TS in the Central Gulf.

Yeah, it probably will end up being an outlier. And correct me if I'm wrong, but I think the surface low worked its way down from the upper levels but didn't really become tropical . Current surface chart has it hooked into a surface trough over to 99l. I guess in this season, heat coming out of the western basin and Gulf has mostly been in the form of occasional weak surface systems and tropical surges like we saw in North Florida over the last 24 hours. There have also been some really deep upper troughs into the central and western gulf that you'd think would paint a bullseye across Florida. Strange year but not the nearly dead one a lot of us imagined.
