WPAC: NEOGURI - Post-Tropical

[cycloneye]

00z Best Track almost cat 3. If what Humberto has done is impressive, what Neoguri is doing is also in that category.

Wow, that was unexpected. Reminds me of when Leslie last year suddenly became a Cat 2.

And more impressive is where it is in latitude.

[Hayabusa]

This one is really performing especially at that latitude, unlike Bualoi can't even open an eye.

Now forecast by JTWC to be once again a major cane but this time wont last long as cat 3 as the final demise will come when it turns extratropical in 2 days.

A major tropical cyclone that close to the Alaskan Islands, an area that is extratropical cyclone breeding grounds seems wrong. The waters there are so cold. Tropical cyclones usually don’t make it this far north in the WPAC, as they usually are post-tropical by then.

That general region has had very high SST anomalies for several months now. Neoguri seems to be enjoying quite a last meal!

Keeps impressing while is in it's last act.

[StormWeather]

Neoguri saying its final goodbye after outlasting Ragasa and possibly soon if it hangs on a little longer, Bualoi.

!!!

[cycloneye]

Going to reach the Aletunian Islands.

[Hurricane2022]

Wow!

Looks like finnally has turned extratropical but anyway have a question. Does anyone has the data about how many Tropical Cyclones have crossed from WPAC to CPAC?

A few come to mind. Omeka crossed the dateline a few times in December 2010. Wene 00 formed in the WPAC as a TD and strengthened in the CPAC. John 94 moved from the CPAC to WPAC back to CPAC. Patsy 59 also straddled the dateline.

Final warning from JTWC. They say it put on an amazing show and that is true 100%.

REMARKS:
290300Z POSITION NEAR 42.9N 173.9E.
29SEP25. TYPHOON 25W (NEOGURI), LOCATED APPROXIMATELY 1417 NM
NORTH OF WAKE ISLAND, HAS TRACKED NORTHEASTWARD AT 28 KNOTS OVER
THE PAST SIX HOURS. TYPHOON 25W HAS PUT ON AN AMAZING SHOW OVER THE
LAST COUPLE OF DAYS, BUT IT IS TIME TO TURN OFF THE LIGHTS, THE PARTY
IS OVER. JUST IN THE LAST SIX TO EIGHT HOURS, THE SYSTEM HAS CHANGED
REMARKABLY, GOING FROM A FULLY COUPLED VORTEX WITH A 20NM WIDE EYE,
TO A RAPIDLY DECOUPLING VORTEX AND CLEAR FRONTOGENESIS. A 282257Z
ASCAT-C PASS REVEALED AN ELONGATED LOW LEVEL CIRCULATION CENTER
(LLCC), WITH A VERY SHARP WARM FRONTAL REGION EXTENDING TO THE
NORTHEAST AND A MORE DIFFUSE COLD FRONT EXTENDING TO THE SOUTH OF THE
LLCC. MAXIMUM WINDS IN THE SCATTEROMETER WERE PEGGED AT 65 KNOTS,
PARTICULARLY IN THE NORTHWESTERN QUADRANT, LIKELY REFLECTING THE
PRESENCE OF A STING JET IN THAT REGION. THE INITIAL POSITION WAS
ASSESSED WITH HIGH CONFIDENCE BASED ON THE ASCAT DATA. THE INITIAL
INTENSITY WAS ASSESSED WITH MEDIUM CONFIDENCE BASED ON DVORAK CURRENT
INTENSITY ESTIMATES OF T5.0 FROM MULTIPLE AGENCIES, AS WELL AS
OBJECTIVE ESTIMATES BETWEEN 77-88 KTS. THE SYSTEM IS UNDERGOING RAPID
EXTRATROPICAL TRANSITION (ETT) AND WILL FULLY TRANSITION TO A STORM
FORCE EXTRATROPICAL LOW WITHIN THE NEXT 12 HOURS AS IT PASSES SOUTH
OF THE ALEUTIAN ISLANDS. THIS IS THE FINAL WARNING ON THIS SYSTEM BY
THE JOINT TYPHOON WRNCEN PEARL HARBOR HI.
