Re: WPAC: VONGFONG - Typhoon
Don't think the dry air is going to be much of an issue for Vongfong. AMSU derived PW analysis does show some slightly lower PW air being entrained into the circulation. However, I place emphasis on slightly, as PWs are analyzed to still be over 2" and overall not too much drier than the surrounding environment. The slightly drier airmass conveniently passes over Palau, so we are able to sample it with the 12Z sounding, and data is consistent with the satellite derived analysis. Additionally, it does not appear that there are any significant dry layers. JTWC's intensity forecast appears on track to me.

Re: WPAC: VONGFONG - Typhoon
With regard to steering, it's actually not particularly strong right now. The stronger it gets, the higher the steering layer becomes, which should give it a little more of a north component (or maybe more accurately less of a west component), but not a ton. Beta drift may also play a part given weak steering, which would also encourage it a little further north. Intensity determines the track is something that I think is slightly overused, but it may indeed play a part here.

Re: WPAC: VONGFONG - Typhoon
If Vongfong wants to become anything more than a low-end Cat 4, that CDO really needs to improve. It’s still quite thin and not that deep.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Re: WPAC: VONGFONG - Typhoon
It's going to have to pull up pretty hard to avoid the northern portion of Samar.

Its headed for Oras and Dolores towns in Eastern Samar and may landfall there before noon. Its on the left part of the track, and the WNW turn is kinda late... is ECMWF on to something?...
Here is a shot of Guiuan Radar this morning.

Re: WPAC: VONGFONG - Typhoon
Northern portion of Eastern Samar might also get clipped. How odd is this, seems like the models and the agencies have not picked up on this continued westward motion?

Re: WPAC: VONGFONG - Typhoon
The radar imagery is still showing a due west motion. I think it's more likely it landfalls in Samar than not at this point.

Re: WPAC: VONGFONG - Typhoon
The 90 kt peak was dropped in the latest JMA forecast, likely due to that continued west motion.
