Sometimes I truly feel bad for the JTWC forecasters

That EWRC really pumped this thing up. Looks like it may have peaked though

2012SEP24 183200 7.1 896.9/ +2.7 /143.0 7.0 7.1 7.1 NO LIMIT ON OFF 15.35 -76.74

The track forecast has been all over the place, too. As Adam pointed out to me, the model spread with this one is a little crazy-- hard to get a handle on it.

Cat 2 for Kadena if JTWC is correct. Luckiest folks in the military.

. 6 HOUR SUMMARY AND ANALYSIS.

SUPER TYPHOON (STY) 18W (JELAWAT), LOCATED APPROXIMATELY 505 NM

SOUTH OF KADENA AIR BASE, OKINAWA, JAPAN, HAS TRACKED NORTHWESTWARD

AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE

IMAGERY SHOWS THE SYSTEM HAS COMPLETED AN EYEWALL REPLACEMENT OVER

THE PAST 24 HOURS, ENDING IN A BIGGER 22-NM EYE. THIS IS CORROBORATED

BY A SERIES OF MICROWAVE IMAGERY INCLUDING ONE FROM A 260644Z AMSU-B

89 GHZ PASS. THE INITIAL INTENSITY WAS BASED FROM THE ABOVE ANIMATION

WITH HIGH CONFIDENCE. THE INITIAL INTENSITY WAS AVERAGED FROM DVORAK

ESTIMATES FROM PGTW, KNES, AND RJTD RANGING FROM 127 TO 140 KNOTS.

UPPER LEVEL ANALYSIS INDICATES THE CYCLONE HAS MAINTAINED A MESOSCALE

ANTICYCLONE OVERHEAD AND IS APPROACHING A RIDGE AXIS TO THE NORTH IN

AN AREA OF LOW (05-10 KNOT) VERTICAL WIND SHEAR. ANIMATED WATER VAPOR

IMAGERY SHOWS CONTINUED EXCELLENT RADIAL OUTFLOW ENHANCED BY A

POLEWARD STREAM INTO THE BACK END OF A MID-LATITUDE SHORTWAVE THAT

PASSED EASTWARD TO THE NORTH AND IS NOW TO THE NORTHEAST. STY 18W IS

TRACKING ALONG SOUTHWESTERN PERIPHERY OF AN EXTENSION OF THE

NEAR-EQUATORIAL RIDGE (NER)TO THE EAST THAT HAS SINCE REBUILT AFTER

THE TROUGH PASSAGE.

Are they? It looks to me like they have it recurving just E of the island-- unless I'm misreading it?

The JTWC, by the way, keeps it well offshore in their new forecast.

Josh, I was basing that on what a colleague was showing me. Maybe he was looking at an old forecast?

Anyway, great looking typhoon...

unlike with Sanba and Bolaven, it wasn't that difficult to find a reporting station that had typhoon-sustained in the Japanese Islands... scouring METARs and the JMA AMeDAS, the highest sustained winds i've found so far was 70kt... the highest gust i've found was 115kt, while the lowest pressure i've found so far was 952hPa... we'll probably see higher winds as Jelawat makes landfall anytime soon... :pimp:

Where were those readings?

Where were those readings?

the pressure was recorded in Miyako-jima.. the 70kt sustained were recorded in numerous stations, small islands located 200-300km southwest of Okinawa... i found the 115-kt sustained in Tokashiki although i do have to note the station is located roughly 600ft ASL... the nearby station closer to sea level had a gust of 100kt..

Wait-- 115 kt sustained?
