Tropical Storm Wilma Forms in the Western Caribbean
      #58455 - Mon Oct 17 2005 07:30 AM

Tropical Depression 24 has become Tropical Storm Wilma. The 21st named storm. This is the highest the modern naming convention has reached to, and ties the 1933 record of number of tropical storms for the year. There exist no more 2005 names for the Atlantic basin.

Wilma's track has shifted more westward, and the official track calls for it to clip the Yucatan. Trends have been toward the west, so at the moment I still think a more westward motion is the most likely, generally falling along the National Hurricane Center's track.

Comments/Feedback on the maps look here.



There may be an eventual turn north, so those along the gulf will want to keep a watch on it. But for now, discussing landfall in any particular United States location is premature. I'm not sold on the ridge breaking down enough for it to move much north at all, at least in the next several days.

IF you go by models, only one major model suggests a northward motion, and this is what concerns me for the US, but most of the models continue it westward.

At this time it seems prudent that we watch it, but I'd imagine those on the Yucatan should be watching it more. I'm in the camp that thinks it will stay further south and west, but it is still vital to watch trends over time. We have time to watch and prepare if something were to occur.

Both the 06Z GFS and the 00Z CMC are showing a northward movement between the Yucatan and Cuba followed by a hook east into FL. The rest of the models show Wilma either clipping the tip of the Yucatan of fully impacting the Yucatan. GFDL is calling for possibly a Cat 4 again, though not even sustaining that until the Yucatan. I suspect now that we have a TS, we'll get better model initialization and we might start to see some more reliable (and less divergent) tracks coming out.

What concerns me most this a.m. is the GFDL. This model has been the outlier all season but has tended to be rather reliable. I am afraid the westward motion will change now with better initialization.... we shall see.

Well.... this is interesting! The newest GFDL appears to have shifted back toward the western tip of Cuba, and the LBAR is even further east, calling for Wilma to cross near Havana (I think that's where Havana is), and then move across the peninsula south of Laka Okechobe(sp?). These models make the NHC forecast seem much more reasonable than the earlier runs did (which were all west of the NHC forecast)... but they also bring to light the fact that we just don't know this far out where Wilma is going to go.

Edit: I just saw others posting while I was typing the above.
Random: The models were in very good agreement earlier, but now the latest runs seem to diverge again - or maybe they've just shifted back to the east and the models that are showing a Yucatan landfall have not been updated yet (I know these models are older runs than the current GFDL and LBAR, but don't know when they will be updated).

It could be yet another frustrating week along the central and eastern Gulf Coast.


Edit 2: WU has updated the GFS, which now calls for a turn to the north and eventually NNE, looks like the Big Bend or south of there longer-term.

Actually there are three that call for it moving into the GOM. THe 6Z GFS now has it crossing west central Florida as well as the CMC. The Euro also moves it into the southern GOM after brusing it into the Cozumel. The NOGAPS and UKMET have the western solution across the Yucatan. The NOGAPS doesn't strengthen Wilma much at all, but it hasn't since Friday. So the Camp is split down the middle. Problem is IMO, its a slow mover, and if it waits in the GOM for a shortwave to pick it up it could be a problem. But this is all speculation. For all we know it could plow into Honduras and fizzle as a TS. Future runs will vaisilate back and forth. We'll wait and see. Cheers!!

You're right; the 6Z GFDL has shifted right; further right than the NHC path, and much quicker.

Well there goes the impressive convection off to the south again. At first glance it looked like our errant toddler of a TS had decided to make a beeline for Nicaragua when most of us weren't watching, but looking at the circulation and then the upper level winds for the last 24 hrs convinced me she is still going nowhere. The dry air has impinged on the outflow to the NW, but the boundary between them is not moving, and there is still good outflow. I have to admit this really is painfully slow development; patience is still the order of the day. So, we'll have to see what another 24-48 hours brings.

[Brought forward from previous thread}

So, TD24 finally blossoms into Tropical Storm Wilma. It's taken what seems like an age since the NHC classified her as a TD and for a while it looked like she was stagnating. I've seen the model runs like everyone else and it appears to me now that the only thing that's predictable about a tropical system is it's unpredictability. NHC now has it moving over the Yucatan and into the GOM but, who knows really, Wilma may decide to take a turn to the west and move over central America into the Pacific. We'll have to give her more time before she truly makes her intentions known.

Just my slant on things.

Wilma another erratic and frustrating storm to forecast.
It is a bit comforting to see the modeling continue to move Westward but
how much faith can we really put into the models when the storm is
moving so slowly.
It's going to be a wait and see event all week.

It seems all the models are moving north instead of west now. What causes the models to swing so quickly with such a slow moving storm?

Isn't it true that landfall connot be accurately predicted more than a couple of days out? It is important not to concentrate
on the black line but look at the cone. I have heard several people here complain about the forecast of Rita's track and I
have tried explain that two days out they were saying our area. You can't expect
them to know five days out. I think the problem is the media and the hype with the big storms.
But we were in the cone for days. I thought they did a good job.
Wilma looks like she may be tougher to forecast but of course the Gulf coast should keep an eye on her just in case. I was hoping we
would be through with the big storms and just reach Alpha with small ones (to set a record). But of course, Wilma may decide
not to become a hurricane. We will just have to wait and see. By the way, does anyone think this will be the last one or do ya'll
think there will be an Alpha?

Could Wilma continue heading south or southwest and not make another turn, methinks she could. Even if she turns west in the next 12 hours I think she would be catching land which would knock her out somewhat.

This is only what I've heard on our local news, but they seem to be valid reasons: 1) the HP system in the GOM is expected to move westward in a couple of days. I believe this feature is what is (for now) keeping Wilma from moving anywhere. Once this system retreats westward, it will allow Wilma to move in a general northerly direction.
2) There is a cold front coming down from the Plains that could pick up Wilma once she starts moving more northward and depending on where Wilma is and when it picks it up, will probably be where Wilma eventually ends up.
The "where" cannot be answered right now, though. I would say that everyone from Florida to N.O. needs to be paying attention to this storm. I do know that our local weather stations are a bit more concerned with this storm *at this time* based on these two weather features.
Hope that helps and hope that I explained things correctly! If not, anyone can feel free to correct my post!

Just think of Wilma as a self propelled hot air vaccuum. She will follow the hot temperatures, and the path of least resistance. If you figure where that is, you will know where she is going. If she finds some deep warm eddies she will take her time over them. She will be the clean up person for this season and will be finishing off all the spots that the other storms did not get.,

yes it is, asking over and over again for the mets to give a landfall location is ridiculous, but some do it anyway.

About the Models...
The 00Z and the 6z, etc.. are those different run times?
Also, I see that the GFS 00Z Had the storm West and the GFS 6Z has a more W and then NE Component taking it into the West Coast of Florida. So I guess each run can be pretty different from the one prior.
Thanks for all of the knowledge

I have the most faith in the GFDL model,it has been very good in the past.It is now well east of the NHC track.Again this all comes down to timing of different factors.The more time that it does not go west,will mean a more east track down the road.I agree that all of the state of Florida and points west need to watch this one close,as it looks like it could be a major cane.

How true that is! If you think about, we really don't know where it will make landfall UNTIL it actually MAKES landfall. Yes, of course, the closer a storm gets to making landfall, the narrower the cone gets....but it has not been unusual for a storm to make landfall 50 miles to the left or right just as it goes in.
We'll have to be patient with this one. There is no way that anyone can predict where this thing will go right now. Just be prepared and you'll be okay.

Hey Coll, you are right, looking at all the long range models, CMC, GFDL, and GFS all seem to pretty tight with their track (and it's early) and NOGAPS and UKM seem to take a similar path. It is and will be a wait and see probably till tomorrow for more consensus and even then as you said as we had seen with Charley, anything can change in a hurry.
