Pressure in Muroto is down to 960.3 hpa - 35.7 m/s sustained wind.
BT pressure of 961 hpa is trash. lol

The current SATCON estimate is 20 mb lower. I doubt it's that low, but yeah, best track is a bit too high.

Re: WPAC: JEBI - Typhoon
JMA’s intensity estimate of 945mb/85KT is very close to reality I would say.

Re: WPAC: JEBI - Typhoon
I might go 950-951 mb based on that.

Lnadfall intensity 950mb/85kt according to JMA. Record-breaking wind speed reported from various weather stations near Osaka and Wakayama.

Re: WPAC: JEBI - Typhoon
Record-breaking storm surge reported from Osaka as well. Possibly the strongest storm affecting this region since Nancy’61.

Re: WPAC: JEBI - Typhoon
Maximum sustained winds of 90.4 knots (10-minute average) were recorded in Kansai International Airport but such a high wind speed may be attributed to channeling effect. Nevertheless, landfall intensity estimate from JTWC is likely too low.

Re: WPAC: JEBI - Typhoon
Using KZC, I get a 90-95 kt 1 minute wind estimate with the estimated 950 mb pressure and other inputs from JTWC, which seems reasonable to possibly a little low based on surface obs.

The bridge is the only way to get to the airport from Osaka. Looks like some severe disruption to air traffic in the nearby region.

Re: WPAC: JEBI - Typhoon
According to JMA, Jebi is the first typhoon since Yancy'93 making landfall over the Japanese main islands with sustained winds of 85KT+. Yancy made landfall over Kyushu with sustained winds of 95KT.

What landfall intensity does JMA have Goni '15 at? I thought that was an 85 or 90 kt landfall in west Kyushu.

Re: WPAC: JEBI - Typhoon
SATCON seemed to do very well actually with landfall intensity. The 0230Z intensity estimate was 94 kt (one minute)/948 mb, which lines up pretty well with the JMA estimate and appears much better than the one from JTWC. It's interesting to note that SATCON was consistently much higher than the JTWC estimates after peak intensity all the way until landfall.

According to JMAs database (Digital Typhoon), Goni was 85 knots / 945hpa before smashing into Kyushu
