well unfortunately Im still not sold on the whole idea of matthew completely dissipating. it could still leave behind enough of it low level circ to still be called matthew. I see no reason to talk about it in another thread until matthew is dead and the other system is for sure separate from matthew. right now all we have are models showing a mess..

I think I remember way back to the first storm of the year.. Alex.. Alex was huge and I believe that I asked why Alex was so large, and the response was something about developing on the eastern end of a monsoon trough. Now the Nogaps model, has developed a very large system.

Could this be the very same reasoning behind this?

HWRF is right there with the GFS and EURO except it maintains matthew.

That's not really what the models are showing. The HWRF, for instance...is not actually showing that hook. If you look at it very closely...it is showing the same thing the GFS is showing: Matthew moves WNW...dissipates...and at the same time a large/broad low forms over the NW Carib...and another low forms east. However...due to the way the model is trying to track the low level feature...it "follows" the lowest pressure and gives the appearance that it is all one system...Matthew...hooking out to the NE. It should be noted, however, that the HWRF is 60 miles too far north already and is therefor not initializing correctly.

If you take a look at all the global models...and look at the big picture they are painting for you...you see that what they are trying to show you is not a hook of Matthew...but a separate low forming on a broad low/monsoon trof. Matthew is almost inland...and will be onshore or almost on shore by the 21z advisory. As the NHC said this morning...and as the GFS has been showing...the mid level vorticity center from Matthew will decouple from the sfc center over the next day and will dissipate over Guatemala. What's left of the LLC will dissipate over N Guatemala/Yucatan. A broad trof will be left...and that is form Nicole in a few days.

See previous posts. It really doesn't maintain Matthew if you get to the heart of what it is trying to say. Go frame by frame and you will watch it dissipate the LLC that is Matthew...and at the same time...create a large generic area of low pressure after 72 hours over the NW Carib....then it generates a new LLC.

It seens that through all of the analysis, Matthew turns or dies and Nicole forms; the models seem locked on something threatening Florida next week and I don't think I have seen any ProMets discount what the models are saying.
True?

Yep, looks like Mathew is toast. No way at the trajectory he's headed in with the steering current collapsing in a couple days that he makes it back to the western Carib.


Time to look for a new low forming off to the east.

Peeps, at the rate of speed and trajectory Matthew is currently taking it almost seems as if he wants to move straight through CA and go into the Eastern Pacific.

But, realistically I think at the rate he is moving Matthew will get far enough inland where he will stall out in the mountainous terrain of Honduras and Guatemala. My prayers to those people down there as devastating floods are certain to occur down there. I too look for development to occur later in the weekend in the NW Caribbean where we may see Nicole born. We shall see.

I have never seen such confusion about a storm, be it real or dissipated. My head is spinning. Since all bets seem to be off, I prefer to think that Florida will be in the clear.

This is not a forecast of any kind. It is just an expression of my confusion.

Well some models (the ECMF) in particular are certainly hinting that Floridians don't need to worry too much because not only does it seem nearly certain that Matthew will just be a huge rain event in CA but that the 'surprise' system that everyone is so interested in now appears to be just a large, weak low presssure area that misses the US altogether. We shall see but your estimation of Florida now being in the clear has seems to have some validity. It's amazing how mother nature can toy with us so well and our technology and knowledge is left to try to figure out what happened. :wink:

Yep. Fantasy models. Not worth a crap. Even The other fantasy storm that was after matthew is mostly gone. Wow. I had a feeling it was a bunch of bull. But what got me was how consistent the models were. Shows ya. Anything past 3 days is garbaaaage. :roll:

Actually, the Euro is the only one that has shown a miss to the east; every other model shows a Florida hit ;)

Like I mentioned yesterday, much to do about nothing. Thank goodness for everyone along the U.S. Gulf coast areas. There isn't really much to be concerned about with Matthew.

Have fun watching for the next potential system. Enjoy the beautiful weather coming up.

I'm still wondering if what's leftover from Matthew still has a remote chance of becomming a depression again as it moves towards Florida?
Just a bit confused whether or not we should put a fork in it....and move on to whatever storm may be next, maybe in a couple of weeks or so...

From the 5 PM Advisory discussion:

FOR THE PAST FEW DAYS GLOBAL MODELS HAVE BEEN CONSISTENTLY DEPICTING
A TROPICAL CYCLONE IN THE NORTHWESTERN CARIBBEAN SEA TOWARD THE
MIDDLE OF NEXT WEEK. THE MOST RECENT RUNS INDICATE THAT ANY
DEVELOPMENT THERE WOULD LIKELY NOT HAVE CONTINUITY WITH MATTHEW...
BUT RATHER REPRESENT THE FORMATION A NEW TROPICAL CYCLONE.

Matthew is heading for oblivion ... torrential, flooding rains will be his legacy.

The longer-range stuff can be good in the open ocean, but on/near land errors of 50-100 miles in the first three days can completely change the 5-day outlook so the variance increases more rapidly.

What to way to go, firing out extremely cold cloud tops while its well inland. I hope we don't start getting gruesome reports of all the flooding in those areas.

So Matthew isn't the big U.S. threat that models had suggested, at least we have that cleared up.
