Even JTWC has it now going up north then to the West. But like Ozonepete said looks liek its only a matter of time now before it fizzles hopefully!

Models going bonkers now...

Interestingly since Ketsana/Ondoy, these some storms after him have crazy unpredictable tracks?

The models often have trouble with stationary storms, since by definition there are no longer any strong steering currents. And yes, there have been a number of stall-outs this year, including in the Atlantic. This one immediately makes me think of Parma.

This one also looks like it could become annular. If it does it could last longer, even though weakened a lot, because the annular structure is a very stable one.

nida is going to hell o_O i believe this will be the last day of nida as a supertyphoon. the circulation seems to be decaying already, it has been stalled for several hours...

anyway, another threat is coming. 97W is consolidating in the Pacific. it seems that 2009 season wants to end with a BANG...

[quote]

Nice call, since as you see they just downgraded it from super-typhoon to typhoon. And it's becoming clear that when this starts to dissipate it will go down really quickly, like Ida did in the Gulf of Mexico. It's probably going to get hit with shear, dry air, and upwelled cool water all around the same time. Even if there's some kind of LLC left, it won't really matter.

It's probably lower than that now. My guess is about 110 kt.

I agree. Could be 115KT but no more.

The models, as almost always with a stationary system, can't really resolve the motion yet. I'm still pretty convinced it's going north and northeast out along the northern boundary of the STR.

What I'm much more fascinated with right now is that is appears it is becoming annular - the big donut with the large eye. This is a very stable structure, and so it may stay a minimal typhoon or a strong tropical storm longer than forecasted rather than dissipating very quickly.

Madness. Upwelling must be hurting Nida by now, but the latest EWRC looks to be more or less complete. The next 24hrs or so will be interesting.

They can't resolve the eye position yet because it went from quite small to quite large. Looks to me like it's still going nowhere, i.e. stationary.

Upwelling is definitely going on, but it's gone annular, which will stabilize it. That also means there probably won't be any more ERCs. It will probably hang onto the tail end of that boundary between the polar westerlies and the STR for another 24 hours or so and then eventually get pulled northeastward. Beautiful looking storm.
