Re: WPAC: INVEST 98W
Hey Storming, this is the one ECM is developing.
As Pat said most models are developing this one and I think it will be the next big player in the Wpac. GFS takes it through Bashi - CMC, UKMET and ECMWF take it towards Luzon. I'll be watching this one closely!

Re: WPAC: INVEST 98W
Too bad the NCEP page put out the simpler track map showing the model runs from Euro. Maybe they knew I was sneaking on pages that are supposed to be restricted to some.
I'm waiting for the 00z run to see if there will be any changes, though I really feel that this one is SCS-bound.

Re: WPAC: INVEST 98W
As of now the shear isn't that friendly to support a significant strengthening, but you can see that the shear is decreasing on the area around this system and also along its potential track. That's when the action starts.

ASYMPTOTE IN A REGION OF MODERATE VERTICAL WIND SHEAR. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.

Really looking more and more like a TD, exposed TD but one none the less.

Re: WPAC: INVEST 98W
Looking robust now. I can say it is already going there. If it will just continue to develop while staying in the Philippine Sea (without shear interfering), I don't see any reason that this won't be a major one, IMO this can be the rival of Hilary in EPAC. Also in its formative stage, the overall circulation already looks quite huge, Euro could be right in showing a fairly large system east of Luzon.
So far not good, seems that this system will make PI as a passageway before going to Southern China. Well at least PAGASA already mentioned this to the public yesterday.
From Euro
(GFS almost similar with ECMWF)

Long-range from Euro. Still showing a threat to Southern China. (Notice that other one east of PI, ECM been showing that for some time now..)

Maybe ECMWF is annoyed seeing their model runs posted everywhere that's why they made it totally private. Oh well there are GFS and others, or if anyone has an access, please update us.
DT now up to 1.5 accdg to JTWC satfix, I can sense at least a 25-knot TD in their bulletin soon.
