We are still watching what was Invest 93L, who has cycled back to its original starting position and it is expected to get into the Gulf again here soon. Like last time, if it can stay far enough offshore, it may develop more than if it hugged the coast like before. If this is invest designated, it will be 95L this time around rather than the old 93L.


Recon is expected to investigate this area tomorrow if necessary:

Welcome to round 2 of the GFS picking up on the possibility of more wintertime TC action in the Southern Indian Ocean:



These are from the 12Z run. Here is 06Z and 00Z:



And a few frames from the 00Z run:



Just something to watch for. It might not even happen, but it’s still worth watching for because interesting.

[Atlantic]

So we now have 3 concurrently active storms in the Western Pacific (Francisco, Co-May and newly formed 12W)

Speaking of Co-May: the 18Z best track is up to 60 kts and it definitely seems highly likely that it will achieve typhoon status prior to landfall in the northwestern Philippines in about 12-24 hours.

 

[Atlantic]

The NHC and the CPHC have noted an AoI that is expected to develop into a disturbance in a few days. The reason the Central Pacific Hurricane Center has in correlation with the National Hurricane Center noted this disturbance is because it is centered from roughly 145*W to 135*W, and the Central Pacific begins at 140*W and ends at the International Dateline (180*W)

The wording is the same from both sides, but I’ll show it from both:

National Hurricane Center side:
View attachment 45331


Central Pacific Hurricane Center side:
View attachment 45332

All of the models have a circulation on the west side of 140*W, which is inside the eastern region of the Central Pacific basin. Some models even show the possibility that two circulations could spin up in 5 days time (July 28th)

Here’s the GFS:



The EURO-AI:


The ICON:


The CMC (the Canadian model):



The EURO



The EURO, the EURO-AI and the GEM (CMC a.k.a the Canadian model) all have two circulations around 140*W.

Should this disturbance (which by the way is now up to 0/30) form in the Central Pacific, the next name there is Iona. And should a second circulation form up at the same time and be name worthy, the following name after Iona is Keli.

 

[Atlantic]

Co-May is now a 70 kt typhoon, and it is expected to peak at 85 kts (equivalent to a Category 2 in the Atlantic) at landfall in the northwestern Philippines. After that it is expected to quickly move northward and dissapate.

 

[Atlantic]

12W became Tropical Storm Krosa according to JMA

T2509(Krosa) Issued at 2025/07/24 07:20 UTC Analysis at 07/24 06 UTC Grade TS Scale - Intensity - Center position N14°30′ (14.5°) E143°40′ (143.7°) Direction and speed of movement NNW Slow Central pressure 1002 hPa Maximum wind speed 18 m/s (35 kt) Maximum wind gust speed 25 m/s (50 kt) Radius of 30-kt wind area S280 km (150 NM) N165 km (90 NM)

(it was Tropical Depression Krosa by the JTWC, which analyzied the intensity at 12Z as 30kts) 18Z says 35 kts, so it is Tropical Storm Krosa by the JTWC now as well.

But Krosa has to be the wonkiest tropical storm I’ve ever seen:

Just look at it!

 

[Atlantic]

The NHC/CPHC AoI is up to 0/40 now. There is the possibility that according to the NHC and CPHC that a tropical depression could form in the next week or so. The next name in the Central Pacific is Iona.

Time for a blast from the past! These following screenshots are all from 2022, the oldest screenshots I have, and they are from my early days of tracking tropical cyclones.

@Kds86z @KakashiHatake2000


This first one is from the early stages of Hurricane Ian. You can see there that had recently become a Category 1. In the bottom right corner you can see the invest track and cone of what later became the short-lived Tropical Depression Eleven.


The main feature in this one is Super Typhoon Noru, and the other storm is Typhoon Kulap.


Again, Noru and Kulap


Several storms appear in this one: on the left is the remnants of what had been Tropical Storm Newton, and if you look just below the “Sep 21” you can see an invest that would fail to become a TC. Moving into the Atlantic you can see Hurricane Fiona quite clearly, and Tropical Storm Gaston also shows up. In the bottom right is the NHC TWO cone for the Invest that would later become the tragic Hurricane Ian. And another cone, that which would later become Tropical Depression Eleven.


In this one Fiona appears again, and south of Fiona is again the invest that became the infamous Hurricane Ian. The Invest and its cone is that of again the future TD Eleven. The area of convection moving off Africa would later become Tropical Storm Hermine. Gaston also appears in the top of shot.


Now we get to Invest 93L, future Hurricane Ian.


Noru appears in the bottom, but the other storm this time is what would later be named Talas (the storm near Japan)


Featuring Fiona and Gaston, with a small clip of Hermine just underneath the timestamp


From left to right:Noru, Talas, an invest that most likely became Kulap, Newton, TD 10L (Future Ian), Fiona, Gaston, the invest that later became TD 11L, and Hermine

More Noru and Talas


Here is what was at this moment Subtropical Storm Nicole (later a Category 1 hurricane and last hurricane of the 2022 season) and an invest that attempted to become a TS, got so close but ultimately failed.


More Nicole and Invest

The long-tracked Invest to the left is what later became Typhoon Nesat. The depression is Haitang.

This one would later be called Moderate Tropical Storm Balita by Meteo-France.


Here’s one starting Hurricane Lisa (at the time here a weakening Tropical Depression)


Here is the single screenshot I have from Tropical Storm Karl.


From left to right: Tropical Storm Paine in the EPAC, the Invest that later became Hurricane Julia and in the Atlantic MDR, the weakening TD Twelve.


The invest in the South China Sea would later become Tropical Storm Sonca. Invest 98W (Maymay, a Philippine name) failed to form. The invest between 98W/Maymay and what was the tropical depression that became Tropical Storm Haitang was the invest that again became Typhoon Nesat.

The track in this one is of Typhoon Nalgae, and an Invest behind it that failed to do anything. The Invest in the SHEM would not be named but it would become TC 04S.

Straight up Hurricane Martin at 35N in November, classic extratropical origins.


Just Lisa again, but if you look up in the top right, you can see a powerful extratropical cyclone, which was ex-Hurricane Martin.


And finally, then-Subtropical Storm Nicole and the gale-force Invest that attempted to become a TS, but ended up failing to.

Sorry @Atlantic. Missed part 1!

 

[Atlantic]

The disturbance near the CPAC I mentioned previously has been designated Invest 97E. As of 12Z it was located at 10.6N, 137.7W. Another 2.4 degrees W of movement and it will cross into the Central Pacific basin (which begins at 140W). Should it still be an invest by the time it moves into the Central Pacific, the CPHC will likely change the invest designation from 97E to 90C, as that is what they do for EPAC invests that crossover to the Central Pacific basin. They did it for what became Hone last year.
