Those pictures below show the very impressive structure of Super Typhoon Neoguri.

It's really impressive to think that it may still be cat3/cat4 when it reaches Japan.

Although didn't receive 135kt rating until a few hours ago Neoguri likey had peaked last night when JTWC estimate reached T7.0, since then cloud tops have warmed considerably and microwave imagery also indicates an ERC may start soon.
Right now outflow is really expanding to the north which will help to maintain current intensity.

actually, the three "Haiyan chasers" reunited in Okinawa for this typhoon.

If they want to intercept the eye, I think they should transfer to Miyakojima. Okinawa may still receive severe typhoon conditions but the eye could pass closer to Miyakojima, or maybe directly...

SUBJ/PROGNOSTIC REASONING FOR SUPER TYPHOON 08W (NEOGURI) WARNING NR
18//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
SUPER TYPHOON (STY) 08W (NEOGURI), LOCATED APPROXIMATELY 295 NM
SOUTH OF KADENA AB, OKINAWA, JAPAN, HAS TRACKED NORTHWESTWARD AT 15
KNOTS OVER THE PAST SIX HOURS. A 070600Z SSMI MICROWAVE IMAGE
REVEALS STY NEOGURI IS UNDERGOING AN EYEWALL REPLACEMENT CYCLE.
ADDITIONALLY, ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS
A NEARLY ANNULAR EYEWALL HAS CONTINUED TO EXPAND UNDER THE INFLUENCE
OF A VERY FAVORABLE ENVIRONMENT. THE CURRENT POSITION IS BASED ON
THE MSI ANIMATION AND THE MICROWAVE IMAGE WITH HIGH CONFIDENCE. THE
INITIAL INTENSITY OF 135 KNOTS IS BASED ON THE CURRENT STRUCTURE AND
ASSESSMENT FROM DVORAK CURRENT INTENSITY ESTIMATES FROM ALL
REPORTING AGENCIES. UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM IS
LOCATED IN AN AREA OF LOW (05 TO 10 KNOT) VERTICAL WIND SHEAR AND
ROBUST RADIAL OUTFLOW, AS EVIDENT IN THE WATER VAPOR IMAGERY. STY
08W CONTINUES TO TRACK ALONG THE SOUTHWEST EXTENSION OF A DEEP-
LAYERED SUBTROPICAL RIDGE (STR) TO THE NORTH.
3. FORECAST REASONING.
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. STY 08W WILL CONTINUE TO TRACK NORTHWESTWARD OVER THE NEXT 12
HOURS BEFORE TURNING NORTHWARD AS THE STR RECEDES WITH THE APPROACH
OF A MID-LATITUDE TROUGH FROM THE NORTHWEST. BY TAU 24, STY NEOGURI
WILL CREST THE RIDGE AND RECURVE NORTHEASTWARD AS A SECONDARY TROUGH
FURTHER WEAKENS THE STEERING STR. DUE TO VERY FAVORABLE
ENVIRONMENTAL CONDITIONS, FURTHER INTENSIFICATION IS EXPECTED OVER
THE NEXT 24 HOURS WITH A PEAK OF 145 KNOTS. BEYOND TAU 36, COOLING
SEA SURFACE TEMPERATURES (SST), INCREASING VWS AHEAD OF THE MID-
LATITUDE WESTERLIES, AND LANDFALL INTO KYUSHU, JAPAN, WILL SLOWLY
ERODE THE SYSTEM.
C. AFTER TAU 72, STY NEOGURI WILL COMMENCE EXTRA-TROPICAL
TRANSITION AND ACCELERATE NORTHEASTWARD INTO THE COLD BAROCLINIC
ZONE. THE INCREASED MID-LATITUDE INTERACTION, DECREASING SST, AND
LAND INTERACTION WILL CAUSE ITS RAPID DETERIORATION FOR THE
REMAINDER OF THE FORECAST PERIOD. THE AVAILABLE DYNAMIC MODEL
GUIDANCE REMAINS IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE TO THE
JTWC TRACK FORECAST WHICH IS POSITIONED CLOSE TO THE MULTI-MODEL
CONSENSUS.//

The typhoon Haiyan chasers (per iCyclone) are currently in Miyako-jima. They just posted it in Facebook minutes ago, and they said that they had heavy rains because a heavy rainband passed through the location. So, they will get the brunt and full force of the storm and the eyewall may pass over their location. Compared to Naha, the winds here are worse.

Actually, they are correct, and is more than a decade. The last time a category 5 super typhoon impacted the Ryukyu Islands was in 1996, when Super Typhoon Herb indirectly struck the islands. In fact, this may even be stronger. So, if the JTWC forecast verifies, this may be one of the strongest ever to strike the islands, but not indirectly anymore.

Super Typhoons aren't that uncommon up there but since you are talking about Cat 5 STY, last time was in 1999 when Super Typhoon Bart peaked at 140 knots just 47 miles west of Okinawa.

Confusing to use weather unisys because there is so much activity!

Let's try a second time :lol:

Neoguri looks anemic right now, convection is diminishing fast.

The track of Neoguri looks quite similar to Typhoon Shanshan's (2006).
lowest barometric pressure recorded in Shanshan back then was an astonishing 919 hpa at Iriomote.

The eye of Neoguri is perhaps as perfectly round than it has ever been in the storm's lifetime, but the convection is weaker than I've ever seen in such a "healthy" cyclone. I'll be very interested to see what conditions this actually brings to the islands.

Intensity down a little bit, 130 knots, still a strong category 4 Super Typhoon and still forecast to strengthen to a category 5 monster!

Okinawa and Mainland Japan in the right front quadrant!
