REMARKS:
060900Z POSITION NEAR 24.5N 131.0E.
TYPHOON (TY) 20W (MELOR), LOCATED APPROXIMATELY 235 NM SOUTHEAST OF
OKINAWA, JAPAN, HAS TRACKED NORTH-NORTHWESTWARD AT 14 KNOTS OVER THE
PAST SIX HOURS. RECENT ANIMATED MULTISPECTRAL IMAGERY CONTINUES TO
SHOW A FULLY-DEVELOPED TYPHOON WITH A WELL-DEFINED EYE AND ANIMATED
WATER VAPOR IMAGERY INDICATES THAT TY MELOR HAS DEVELOPED BETTER
POLEWARD OUTFLOW INTO THE MID-LATITUDE WESTERLIES AS IT IS STARTING
TO CREST THE SUBTROPICAL RIDGE AXIS. HOWEVER, RECENT INFRARED
IMAGERY REVEALS WANING DEEP CONVECTION AND DVORAK ESTIMATES FROM
PGTW, KNES, AND RJTD HAVE DROPPED IN THE LAST 12 HOURS. THE CURRENT
INTENSITY IS BASED ON THESE DVORAK ESTIMATES. THE CURRENT POSITION
IS ALSO BASED ON FIXES BY THE SAME AGENCIES, WITH HIGH CONFIDENCE.
THE CURRENT NUMERICAL MODEL AIDS ARE IN GOOD AGREEMEENT WITH THE
SYSTEM STARTING RECURVATURE WITHIN THE NEXT 12 TO 18 HOURS. THE AIDS
ALSO AGREE ON LANDFALL WEST OF TOKYO, JAPAN, AFTER TAU 36. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 060600Z IS 38 FEET. NEXT WARNINGS AT
061500Z, 062100Z, 070300Z AND 070900Z. REFER TO TROPICAL STORM 19W

Re: WPAC : TYPHOON MELOR (20W)
This track is really bad for Japan, especially at the coast from central to northeast. It could quite possibly strafe the coast from the Kii peninsula all the way up. Yikes! Just have to hope it weakens more quickly.

Re: WPAC : TYPHOON MELOR (20W)
Typhoon Melor weakens on track to Japan
Melor has weakened from a super typhoon to a typhoon but is still packing dangerous wind speeds of 138 mph (222km/h) with gusts to 167mph (268km/h).
The storm, whose name means jasmine in Malay, is heading north-west to Japan where it will strike the southern islands of Okinawa on Wednesday and the main island of Honshu on Thursday. Residents are bracing themselves for heavy rains, violent winds and rough seas.
In a phenomenon known as the Fujiwara effect, the presence of typhoon Melor is keeping tropical storm Parma virtually stationary off the north-west coast of the Philippines.

Re:
Outflow has become much less defined during the past 6 hours, but Melor has managed to generate a new burst of convection around the center. I agree that shear won't weaken Melor much since the trough is negatively tilted. However, passage over cooler water will have some weakening effect. Melor is expected to moving slower than most typhoons approaching Japan, only about 20 kt.
If Melor makes landfall on or just west of the Kii peninsula and tracks west of Kyoto and Osaka even as a 100 kt typhoon, it would produce major damage, probably similar to Typhoon Mireille in 1991. Despite the JTWC advisories putting Melor at 115 kt, satellite suggests an intensity closer to 100-105 kt now. I expect about 90-95 kt at landfall.

I suspect it will hold its own, possibly re-intensifies as the eye contracts a little during the next 24, then slowly weaken on final approach. Probably 100KT 1 minute sustained or 85KT 10 minute as JMA has

Just checking in to say we're okay here...though it is 3:30 a.m. and I am just now ready to get to bed. The noise level has died down some outside. Some video I took earlier before it got very intense: http://www.youtube.com/watch?v=YmfBjflIBXo

Great analysis. Seems right to me. The interesting thing is the JMA and JTWC are very close on landfall now at the Kii peninsula, but diverge fairly significantly after that, with JMA track putting most of JAPAN in the dangerous right side while JTWC keeps mostly just the coast in the right front quadrant.

Re: WPAC : TYPHOON MELOR (20W)
I still have reservations about the JMA forecast though, AFTER landfall. Look at the GFS forecast chart for 500mb heights for tomorrow morning. (Sorry it is a little hard to read. Why can't we get better upper air charts for Asia?) Anyway, you have rising heights over the Sea of Japan west of northern Japan and falling heights to the east, i.e. the westerlies (500mb a good proxy for steering level at this latitude) are coming straight into northern Japan. It makes it hard for me to envision this cyclone making it over the western side of Japan after landfall. I also drew in the mid to upper level winds coming over Korea into Japan. If you watch the satellite loop you'll see it quite clearly. All of this just makes me think the JMA is not recurving it sharply enough. Just my thoughts. And I know you guys (Derek and Jconsor) explained the problem with JTWC (thanks for the inside info) but as they say, even a stopped clock is right twice a day...

Re: WPAC : TYPHOON MELOR (20W)
Though the eye is obscured, there's a lot of strong convection building just before daylight.
