2025 Global Tropical Cyclone Season Discussion

[Atlantic]

This year's global tropical cyclone season is nearing its' end so I am getting a head start on the upcoming 2025 season and starting this thread. Current climo models suggest we will see a weak La Nina to start with, but that it may transition back into a cool neutral instead by the NHEM peak.

If ENSO warms up faster than expected throughout the year, then we may see neutral or even warm-neutral conditions by peak NHEM season. This may make the Pacific a bit more active than expected and could also lead to a pretty busy tornado season as well.

If ENSO warms up faster than expected throughout the year, then we may see neutral or even warm-neutral conditions by peak NHEM season. This may make the Pacific a bit more active than expected and could also lead to a pretty busy tornado season as well.

Do you think that'll be the case?

 

[SouthFLwx]

Do you think that'll be the case?

I'm not sure, that's why it's important to closely monitor ENSO trends.

 

[Atlantic]

This year was an example of what was very early on expected to be a Super La Nina by now but is instead a cool neutral or maybe now a weak La Nina.

So I understand what you are saying.

have you seen "francisco" in the WPAC naming list?
As in Lachowski?

We are now in 2025, with two invests from last year still active: 92S and 94S (Tropical Low 08U in the Australian Region) I will continue to talk about them even if one or both form on the 2024 version of this thread.

Our first Invest of 2025 came quickly in the form of Invest 90W, the first NHEM Invest of the year as well

 

[Atlantic]

The SST’s off of the northern coast of Australia are stupidly high right now.

 

[Atlantic]

Dikeledi may have been the final Invest designated system of 2024, also be classified in the Australian Region as Tropical Low 09U, but it is now the first TC of 2025 and the SWIO’s earliest D- named storm in a few seasons. The D- name has been used in February these past few seasons.

We also have two other areas of interest around the world-all in the southern hemisphere. First one is Invest 97S-also known as Tropical Low 09U in the Australian Region. It has a high chance of forming in the next 24-48 hours and the JTWC has issued a TCFA on it.

The other system is Invest 98P, also known as Tropical Depression 04F in the South Pacific. This system is broad at the moment but organizing slowly. It is a part of a massive line of thunderstorms currently active in what is called the South Pacific Convergence Zone. 98P has a low chance of forming in the next 24-48 hours.

MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL CYCLONE 07S (DIKELEDI) WARNING
NR 001//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.

SUMMARY:
INITIAL POSITION: 13.6S 60.1E
INITIAL INTENSITY: 40 KTS
GEOGRAPHIC REFERENCE: 422 NM NORTH-NORTHEAST OF PORT LOUIS,
MAURITIUS
MOVEMENT PAST 6 HOURS: WESTWARD AT 15 KTS
SIGNIFICANT WAVE HEIGHT: 18 FEET

SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION:
ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS TROPICAL
CYCLONE 07S WITH PERSISTENT CONVECTION OVER THE OBSCURED LOW-LEVEL
CIRCULATION CENTER (LLCC). STRONG WESTWARD AND POLEWARD OUTFLOW IS
APPARENT WITH THE PRESENCE OF WELL-DEFINED CIRRUS FILAMENTS
EXPANDING OUTWARD IN THOSE DIRECTIONS. ENVIRONMENTAL ANALYSIS
INDICATES THAT 07S IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT
CHARACTERIZED BY THE ROBUST OUTFLOW ALOFT, LOW (10-15 KTS) VERTICAL
WIND SHEAR, AND WARM (28-29 C) SEA SURFACE TEMPERATURES. THE
INITIAL POSITION IS PLACED WITH MEDIUM CONFIDENCE BASED ON THE
ANIMATED EIR. THE INITIAL INTENSITY OF 40 KTS IS ASSESSED WITH
MEDIUM CONFIDENCE BASED ON THE AGENCY DVORAK FIXES LISTED BELOW.
ADDITIONALLY, A 091137Z CIMSS DMINT ESTIMATE WAS 42 KTS.

INITIAL WIND RADII BASIS: OBJECTIVE BEST TRACK

CURRENT STEERING MECHANISM: NORTHERN PERIPHERY OF A SUBTROPICAL
RIDGE (STR) POSITIONED TO THE SOUTH.

AGENCY DVORAK AND AUTOMATED FIXES:
PGTW: T2.5 - 35 KTS
KNES: T3.0 - 45 KTS
FMEE: T3.5 - 55 KTS
FIMP: T3.5 - 55 KTS

FORECASTER ASSESSMENT OF CURRENT ENVIRONMENT: FAVORABLE
VWS: 10-15 KTS
SST: 28-29 CELSIUS
OUTFLOW: STRONG POLEWARD

ANALYSIS CONFIDENCE:
INITIAL POSITION: MEDIUM
INITIAL INTENSITY: MEDIUM
INITIAL WIND RADII: LOW

3. FORECAST REASONING.

SIGNIFICANT FORECAST CHANGES: THIS INITIAL PROGNOSTIC REASONING
MESSAGE ESTABLISHES THE FORECAST PHILOSOPHY.

FORECAST DISCUSSION: 07S IS FORECAST TO CONTINUE TRACKING
WEST-NORTHWESTWARD ALONG THE NORTHERN PERIPHERY OF THE STR TO THE
SOUTH THROUGH TAU 48. LANDFALL IS FORECAST TO OCCUR AROUND TAU 48
ALONG THE NORTHERN TIP OF MADAGASCAR. AFTER TAU 48, THE SYSTEM IS
EXPECTED TO MAKE A SOUTHWESTWARD TURN AS IT ROUNDS THE RIDGE AXIS.
AROUND TAU 96, 07S WILL BEGIN TO TRACK MORE SOUTHWARD THROUGH THE
MOZAMBIQUE CHANNEL AS IT RUNS ALONG THE WESTERN PERIPHERY OF THE
STR. REGARDING INTENSITY, 07S IS FORECAST TO STEADILY INTENSIFY
OVER THE NEXT 36 HOURS TO A PEAK OF AROUND 70 KTS AS THE
ENVIRONMENT REMAINS CONDUCIVE. NEAR TAU 48, 07S WILL MAKE LANDFALL
AND BEGIN TO WEAKEN. THE AMOUNT OF WEAKENING WILL DEPEND HIGHLY ON
THE AMOUNT OF TERRAIN INTERACTION WITH NORTHERN MADAGASCAR. IF IT
MAKES LANDFALL FURTHER SOUTH, THEN IT COULD WEAKEN MUCH MORE THAN
CURRENTLY FORECAST. AS IT STANDS, 07S WILL BRUSH THE NORTHERN TIP
AND THEN WEAKEN TO AROUND 60 KTS. IT WILL MAINTAIN INTENSITY THROUGH
TAU 120 AS INCREASED SHEAR (20-25 KTS) FIGHTS THE WARM (30 C) SEA
SURFACE TEMPERATURES WITHIN THE MOZAMBIQUE CHANNEL. IN THE EXTENDED
FORECAST (PAST TAU 120), FURTHER INTENSIFICATION IS PROBABLE AS THE
POLEWARD OUTFLOW CHANNEL WILL GREATLY IMPROVE.

MODEL DISCUSSION: NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT
REGARDING THE TRACK OF 07S THROUGH TAU 48. AFTER TAU 48, MODELS
DIVERGE DUE TO THE SHARPNESS OF THE TURN AROUND THE STR. GFS TAKES
A WIDER TURN, CLOSER TO MOZAMBIQUE, WHILE ECMWF TAKES A SHARPER
TURN, CLOSER TO THE WESTERN COAST OF MADAGASCAR. INTENSITY GUIDANCE
IS IN WORSE AGREEMENT. RAPID INTENSIFICATION (RI) PROBABILITIES
OVER THE NEXT 36 ARE HOVERING AROUND 20 PERCENT, SO IT SHOULD NOT
BE OUT OF THE QUESTION. THE JTWC INTENSITY FORECAST IS PLACED WITH
OVERALL LOW CONFIDENCE DUE TO THE RI CHANCE AND THEN THE VARIANCE
REGARDING THE AMOUNT OF LAND INTERACTION WITH NORTHERN MADAGASCAR.

FORECAST CONFIDENCE:
TRACK 0 - 72 HR: MEDIUM
TRACK 72-120 HR: LOW
INTENSITY 0 - 72 HR: LOW
INTENSITY 72-120 HR: LOW//

@Atlantic I wonder if Kenneth and Lidia may get retrospectively retired because of the fires

Kenneth and Lidia from 2023?? I could see Lidia retroactively being retired, but not Kenneth. Kenneth was out to sea.

Sorry, I figured out after that post (Like just after I posted).

I could definitely see Kenneth being retired now. If we had a storm named Kenneth in the future it might bring back unwanted memories, as in the name is sensitive.

Lidia not as much based off of the image above.

I won't rule it out, because Dora got retired due to fire-related events as well
plus Kenneth and Lidia are in the same basin as Los Angeles and just in case Kenneth or Lidia take a Hilary type path in 2029

Dikeledi has been rebounding in intensity after going further inland over Mozambique than expected:



Models are suggesting this will continue its recurve around the high pressure ridge in place northeast of it and eventually turn eastward after passing Madagascar here soon. It will likely turn post-tropical in about 48 hours or less.

 

[Atlantic]

Meanwhile... in the Australian Region the stupidly high SSTs continue:

 

[Atlantic]

Overnight Dikeledi became the first Major of 2025 overnight (for me at least). It is also the third Major cyclone in the SWIO in a row. It peaked at 115 mph.
