Choi Wan down to Cat4
Posted by JAC on 9/17/2009, 7:45 am

Poleward Outflow-Channel due to TUTT to the east of Choi Wan has diminshed causing the drop in intensity.

Anti-cyclone center is slightly displaced 30 miles NW of the COC.

Eye-wall is just short of being a Hot-Tower.
Looks like two small Hot-Towers firing on the periphery of the TC.
I have never seen so many Hot-Towers fire within a TC like this before.

Core still hot at 8C.

Now looks like a little sharper recurve on the latest forecast track.

Tokyo could be OK.
