Yep. The Ensembles, though not consistent with it, have been hinting a lot about the Gulf/Western Caribbean next month. Which makes sense.

It’s been a week that rivals the October 2023 group of tropical cyclones this week (in a week or so of October 23’ we had Otis, Bolaven, Tej, Hamoon, Lola and Tammy)
This week had Ragasa, Neoguri, Gabrielle and Humberto (two Category 5 cyclones in a week)

lol! When we thought that Neoguri was done basically after falling all the way back from Category 4-equivalent status back to a Tropical Storm, we all thought it was over. Nah- it’s not.
Say hello to Neoguri almost being a major typhoon again coming all the way back from a tropical storm. 95 kts right now.

Neoguri is forecast to regain 100 kt winds (115 mph) closer to the flipping ALASKAN ISLANDS than the equator!
By the time a cyclone has reached the latitude that Neoguri has reached, it usually is turning post-tropical or already is!
And yes, that’s the IDL at 180 degrees

Neoguri has nearly managed to regain its old intensity of 125 kts (145 mph) at a ridiculously high latitude of almost 40N, which is nearly unheard of for the WPAC.
Current intensity is 110 kts (125 mph) according to the JTWC.
The JTWC says that Neoguri has a few hours left to reach an intensity a little higher than 110 kts before very unfavorable conditions set in.
Since this is a rare breed of Western Pacific tropical cyclone, I am going to post everything the JTWC warning has on Neoguri:

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
SUMMARY:
INITIAL POSITION: 35.8N 164.8E
INITIAL INTENSITY: 110 KTS
GEOGRAPHIC REFERENCE: 893 NM NORTHEAST OF MINAMI TORI SHIMA
MOVEMENT PAST 6 HOURS: NORTHEASTWARD AT 25 KTS
SIGNIFICANT WAVE HEIGHT: 44 FEET
SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION:
ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A NEARLY
PERFECTLY ROUND EYE FEATURE OF TYPHOON (TY) 25W (NEOGURI) AS IT IS
ACCELERATING ON A NORTHEASTWARD TRACK. DESPITE ITS CURRENT MID-
LATITUDE POSITION, THE SYSTEM HAS RAPIDLY INTENSIFIED AT AN
IMPRESSIVE RATE OF 40 KTS IN THE LAST 24 HOURS. AS A RESULT, IT NOW
FEATURES A NEARLY SYMMETRICAL CONVECTIVE CANOPY, SURROUNDING THE 20
NM WIDE EYE. ENVIRONMENTAL ANALYSIS REVEALS A ROBUST POLEWARD OUTFLOW
ENHANCED BY AN UPPER-LEVEL SHORTWAVE TROUGH. ADDITIONALLY, THE LAST
MOMENTS OF MARGINALLY FAVORABLE CONDITIONS INCLUDE BORDERLINE (26-27
C) SEA SURFACE TEMPERATURES (SST). THESE FACTORS ARE OFFSET HOWEVER
BY SIGNIFICANTLY AND RAPIDLY INCREASING VERTICAL WIND SHEAR,
CURRENTLY ASSESSED AT 20-25 KTS, AS WELL AS DRY AIR PRESSING OVER THE
WESTERN PORTION OF THE CIRCULATION. THE INITIAL POSITION IS PLACED
WITH HIGH CONFIDENCE BASED ON THE EASILY IDENTIFIABLE EYE FEATURE,
WHILE THE INITIAL INTENSITY OF 110 KTS IS ALSO ASSESSED WITH HIGH
CONFIDENCE BASED ON A COMBINATION OF AGENCY DVORAK AND OBJECTIVE
ESTIMATES LISTED BELOW.
INITIAL WIND RADII BASIS: PERSISTENCE
CURRENT STEERING MECHANISM: SUBTROPICAL RIDGE (STR) TO THE EAST
AGENCY DVORAK AND AUTOMATED FIXES:

CIMSS D-MINT: 97 KTS AT 280200Z
CIMSS D-PRINT: 102 KTS AT 280700Z
FORECASTER ASSESSMENT OF CURRENT ENVIRONMENT: MARGINALLY FAVORABLE
VWS: 20-25 KTS
SST: 26-27 CELSIUS
OUTFLOW: STRONG POLEWARD
ANALYSIS CONFIDENCE:
INITIAL POSITION: HIGH
INITIAL INTENSITY: HIGH
INITIAL WIND RADII: LOW
3. FORECAST REASONING.
SIGNIFICANT FORECAST CHANGES: THERE ARE NO SIGNIFICANT CHANGES TO
THE FORECAST FROM THE PREVIOUS WARNING.
FORECAST DISCUSSION: TY 25W IS FORECAST TO CONTINUE ACCELERATING,
WHILE TRACKING ALONG THE WESTERN PERIPHERY OF A DEEP-LAYER STR TO
THE EAST. AS THE SYSTEM IS CURRENTLY ROUNDING THE AXIS OF THE
RIDGE, IT IS EXPECTED TO SOON BEGIN ITS EXTRATROPICAL TRANSITION
(ETT). RAPIDLY COOLING SSTS AND INCREASING VERTICAL WIND SHEAR ARE
EXPECTED TO RESULT IN DECAPITATION AND QUICK SHALLOWING OF THE
CONVECTIVE STRUCTURE OF THE SYSTEM. UNTIL THEN, TY NEOGURI STILL
HAS A FEW HOURS TO REACH A SHORT-LIVED PEAK SLIGHTLY BEYOND
CURRENTLY ASSESSED 110 KTS. AFTER THAT, ONSET OF AFOREMENTIONED
UNFAVORABLE ENVIRONMENTAL CONDITIONS, AMPLIFIED BY SIGNIFICANT DRY
AIR INTRUSION FROM THE WEST WILL ALL RESULT IN RAPID DETERIORATION
OF TY 25W, PAIRED WITH SIMULTANEOUS AND QUICK COMPLETION OF THE ETT
BY TAU 24.
MODEL DISCUSSION: BOTH NUMERICAL TRACK AND INTENSITY MODEL GUIDANCE
ARE IN VERY GOOD AGREEMENT THROUGHOUT THE FORECAST PERIOD,
RESULTING IN HIGH CONFIDENCE OF THE OFFICIAL JTWC FORECAST. TRACK
ASSESSMENT IS LAID CLOSE TO THE MULTI-MODEL CONSENSUS, WHILE
INTENSITY PREDICTION IS PLACED CLOSE TO THAT OF HAFS-A, WHICH IS ON
THE HIGHER END OF THE CURRENT MULTI-MODEL CONSENSUS SPREAD.

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. THE SYSTEM WILL BE CLOSELY
MONITORED FOR SIGNS OF REGENERATION. MINIMUM CENTRAL PRESSURE AT
290000Z IS 962 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290000Z IS 38
FEET. REFER TO TYPHOON 26W (BUALOI) FINAL WARNING (WTPN31 PGTW).

Neoguri (Japanese Typhoon Number 19) is located 2624 km north of Wake Island, and has tracked northeastward at 52 km/h (28 knots) over the past 6 hours. Minimum central pressure at 29/00:00 UTC is 962 hPa. Maximum significant wave height is 11.6 meters (38 feet).
Neoguri 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 37 km wide eye, to a rapidly decoupling vortex and clear frontogenesis.
A 28/22:57 UTC 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 120 km/h (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 145–165 km/h (77–88 knots).
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 JTWC. The system will be closely monitored for signs of regeneration.

We have Invest 98E in the Eastern Pacific. It could become a TC soon. The NHC gives it a 70/90 shot that it’ll become a TC within the next few days.
Invest 90A was designated just offshore of Western India last night, and models think it could become a brief, short-lived TC in the Arabian Sea
We also have Invest 93W to monitor for the potential to impact or landfall in the Philippines within the next week or so.

Which one is your favorite, @Kds86z?
You can screenshot it or something and just post it here if you want.

Invest 98E in the Eastern Pacific has become Tropical Depression Fifteen-E.
We still have Invest 93W in the Western Pacific, Invest 90A in the Arabian Sea, now joined on the other side of India by Invest 91B.
Another disturbance behind 15E could become the next TC in the Eastern Pacific.

Invest 91B became Cyclonic Storm 01B according to the JTWC this morning, and the NIO has finally unofficially by JTWC standards produced its first tropical cyclone. It is expected to remain weak and possibly dissipate without making landfall.
Invest 93W had a TCFA this morning that I didn’t post, but soon after it became Tropical Depression 27W, and it has now intensified into a currently unnamed tropical storm as Tropical Storm 27W. 27W is also known as Tropical Depression Paolo in the Philippines.
Invest 90A on the other side of India from 01B is up to a Medium chance of becoming a TC within the next 24-48 hours in the Arabian Sea.
The Eastern Pacific has a disturbance that is at 30% in 2 days/80% in the next 7 days.
The next name in the Eastern Pacific is Priscilla.
The next Philippine name is Quedan.
The next international name in the Western Pacific is Matmo.
The next North Indian Ocean name is Shakhti.
