    “[The Google WeatherNext AI team] are showing how the WeatherNext AI model from Google DeepMind and Google Research has achieved state-of-the-art accuracy in predicting a cyclone's track, intensity, and wind structure. On average, the WeatherNext Cyclones model gives forecasters an extra day’s worth of predictive accuracy- delivering an advance equivalent to roughly a decade of historical meteorological progress 🌀
    Here is how WeatherNext is transforming cyclone forecasting:
    • Gaining an Extra Day of Advanced Warning: WN 3-day forecasts are as good as what prior models were able to provide for 2-day forecasts, giving critical time for emergency response.
    • Overcoming Traditional Trade-offs: WN bridges the gap between massive global atmospheric currents (which steer a cyclone's path) and fine-grained thermodynamic processes around its core (which drive its intensity) into a single AI model.
    • Unprecedented Ensemble Scale: Using Functional Generative Networks (FGNs), WN now generates 1,000-member ensembles in less than a minute on a TPU to capture rare, consequential tail-risks like sudden rapid intensification – which means forecasters can see a broader range of possible scenarios.
    • Real-World Impact: During the 2025 Atlantic hurricane season, the WN model helped the National Hurricane Center (NHC) make a historic forecast for Hurricane Melissa by predicting rapid intensification and landfall five days in advance.
    [The] teams are open sourcing the operationalized models (WeatherNext Cyclones and WeatherNext 2), alongside a compact version (WeatherNext 2-mini) that can run on a single TPU in a free public Colab notebook – all with a goal of empowering local organizations worldwide.
    Weather affects everyone. By combining advanced AI with the real-world expertise of human forecasters, we can build a collaborative ecosystem that saves lives and helps communities adapt to a changing climate…”

  5. CW: Severe Tropical Cyclone Narelle, Very dangerous Tropical Cyclone

    Severe Tropical Cyclone Narelle has turned into a very angry swirl, currently a Category 5 on the Australian Scale [Category 4 Major Hurricane Saffir-Simpson Hurricane Wind Scale], and still intensifying, 315km/h or 195mph gusts are likely in the eyewall, the up side is that region of Queensland is more sparsely populated [and actually falls outside our chase territory if it was south of Port Douglas we would have absolutely chased this one], but for the few towns in that region its gonna be a rough night as early morning landfall still looks like what the models have been showing, and its been rather consistant with lining up with models - Nightmare Typhie

  6. 🌊 How ocean eddies affect the intensity of #TropicalCyclones (TCs) 🌪️

    A new #MPIM study using a 5km global #ICON simulation shows that TCs crossing more cold than warm eddies intensify more slowly & stay weaker on average, + there is preliminary evidence of the opposite effect when a TC passes over more warm than cold eddies. The global effect is a net weakening. The study suggests that accounting for mesoscale ocean turbulence could improve TC forecasts.

  8. CW: Tropical Cyclones/Huricanes/Typhoons

    Fina has intensified to Category 3 Severe Tropical Cyclone, giving how much land influence there is you'd expect it to be much more unhealthy, my hypothesis is that the SSTs are around 30ºC which is very warm and quite above the lower threshold of 26.5ºC, rains ahead are extracting energy from land and soil [little bit of the Brown Ocean Effect], since soil and air has far less heat than water it cools off quickly as it goes to latent heat of evaporation and is immediately pulled into the TC [Latent Heat is the true fuel that runs a TC], and there is a steady stream of high levels of moisture which is evident by high dew point temperature [dew point temperature is a measure of absolute humidity, its the temperature you need to cool the air without adding or removing moisture for that air to reach saturation or 100% relative humidity, so a dew point of 27ºC will mean fog/cloud, dew, and generally condensation will start form if you cool the air to 27ºC] - Nightmare Typhie

  9. CW: Tropical Cyclones/Hurricanes/Typhoons, Active Storms, Tropical Cyclone Fina

    The eye of Tropical Cyclone Fina is now clearly visible on Arafura radar, Darwin is now in the warning area, which means they're potentially going to see Cyclone conditions within 24 hrs [Hurricane or Tropical Storm force winds], the City of Darwin has Historical trauma when it comes to Tropical Cyclones being the location of landfall for Severe Tropical Cyclone Tracy December 25th, 1974 which made landfall early morning as a Category 4 Severe Tropical Cyclone [Australian Tropical Cyclone Scale], or Category 3 Major Hurricane [Saffir-Simpson Hurricane Wind Scale], this system is coming in from a different direction and is a lot weaker, it is more analagous to Tropical Cyclone Marcus 2018 which went through the city on a similar trajectory, however there probably will be residents of Darwin who remember Tracy and will be on edge - Nightmare Typhie

  10. CW: Tropical Cyclone/Hurricane/Typhoon, Active Storm

    So Tropical Cyclone Fina has been named and is now Category 1 intensity, the system became category 1 earlier than expected for the reasons I said were holding it back yesterday, so yesterday there were unfavourable windshear over the system, in the last 24hrs the shear has dropped leaving the system with a big buffer of favourable and neutral windshear conditions, with a shear tendency of -10 to -20 kts in the past 24hrs in the vacinity of TC Fina, also attatched are ensemble runs of the GFS and GEPS for TC Fina, taking both the GFS Ensemble and GEPS into account I think for now a lot of the potential tracks that keep it far offshore in tte Arafura and Timor Sea are less likely and ttat the system will likely remain closer to the coast, there is one outlier on GEPS that shows a Gulf landfall at 970-980hPa which would likely be around Category 3 Severe Tropical Cyclone, and its not the only track that landfalls at pressures that would suggest around Category 3 intensity, all of those tracks though sit at beyond the 72 hours mark which I give less weight to - Nightmare Typhie

  11. CW: Tropical Cyclone/Hurricane/Typhoon, Active System

    Looks like we're very close to having the first named Tropical Cyclone of the 2025-26 Australian Region Tropical Cyclone Season, also maybe the BoM can hire proof readers or something, some of the grammar of the technical bulletin remarks tripped me up, but its only 5kts off Category 1 Tropical Cyclone [Australian Tropical Cyclone Scale], which starts at 35kts, I haven't looked at CIMSS yet, BoM mispelt it in the technical bulletin, CIMSS being Cooperative Institute of Meteorological Satellite Studies, which has a lot of good products for forecasting Tropical Cyclones - Nightmare Typhie

    So after looking at CIMSS products my overall initial analysis is that Tropical Low/Depression 02U/97S is is an area of high upper divergence with big difference between low level convergence and upper divergence, more air is being removed from the location aloft than is incoming, this means that pressure has to drop, a sign it is intensifying, while it center is currently in a band of unfavourable windshear it is moving into an area of neutral to favourable windshear which also has a 24 hr tendency of lowering, vorticity is condensed and looks healthy at 850, 700, 500, and 200hPa, sea surface temperatures [SSTs] are above 26.5ºC threshold by a few degrees and while there is some dry air south over land and a little bit of dry air north its situated well and truely within a pocket of moist air, my take away is that right now the shear may be slowing its development, and that as it moves ENE into more favourable windshear conditions intensification may speed up, I think it is likely to at least attain Category 1 intensity, and probable that it will reach a mid Category 2 to threshold Category 3 Severe Tropical Cyclone intensity over the next 72hrs as it moves into that area of lower shear - Nightmare Typhie

    Our pronouns are Su/Sudo/Suselves, however She/Her/Herselves, and They/Them/Theirselves

    Languages: Our L1 is English, we have previous done some work on Esperanto, and Latin, we picked up some French due to frequently seeking information in french resources, and we're currently learning Japanese, right now English is the only language we can reliably produce anything in, likely since we tend to learn languages for literature access, but plan to attempt to add japanese to the list of languages we can produce output for, and maybe french and esperanto in the future, growing up we did start learning Taiwanese Mandarin and German however with both most of that has been lost though we did retain some residual hanzi knowledge that seem to reawaken when we started working on kanji.

    Our system name is subject to change, it was previously the Athena's Realm System, however only one member, arguably two members made that decision on behalf of the entire system, without consulting us, so we're in the process of trying out system names to see which fits us best, but for the time being we will display both "Athena's Realm" and the current trialing system name so it is less confusing for those who know us by our old system name

  15. According to Gallagher Re, the total insured loss from #TropicalCyclones in the contiguous U.S. from 1990 to 2023 was US$556 billion. Normalised to 2023 U.S. dollar values, this translates to an Average Annual Loss (AAL) of US$16.6 billion [...] a repeat of the 1990 to 2023 tropical cyclone season today would result in significantly higher insured losses as a consequence of exposure growth, sea-level rise, and a climate ~0.5°C warmer than 1990: journalofcrr.com/research/03-0

  18. A busy #hurricane season is expected. Here’s how it will be different from the last
    A warm -- yet no longer record-hot -- strip of waters across the #Atlantic #Ocean is forecast to help fuel development of 17 named #tropicalcyclones during the season that runs from June 1 through Nov. 30, according to Colorado State University researchers. Of those tropical cyclones, nine are forecast to become #hurricanes, with four of those expected to reach "major" hurricane strength.

  26. It seems they never interpolated the storm tracks resulting in these weird strings of circles and arcs? And what’s up with the lack of data in the south? While #TropicalCyclones typically don’t form near nor approach the equator, the hard cutoff at around the 6.6°N latitude is an interesting choice.

    Anyway, I can spot 2012’s Typhoon #Bopha / #PabloPH in #Mindanao and 2013’s Typhoon #Haiyan / #YolandaPH in the #Visayas, which tells me that they did use historical data.

  28. It seems that the forecast that Tropical Storm #Trami / #KristinePH will loop back eastward just before #Vietnam 🇻🇳 is still on track. What’s worrying is that the Japan Meteorological Agency is seeing the track veering south which means that the storm will likely hit the #Philippines 🇵🇭 a second time.

    There’s also the new Tropical Storm #KongRey / #LeonPH that while not expected to make a landfall in the Philippines will still have a wider effect.

  29. Eep! 😱 While I am not personally severely affected by Tropical Storm #Trami / #KristinePH (we’ve had some moderate wind and rain), the fact that this system is moving extremely slow and is dumping tons of rain is very concerning for those in the storm’s path. The Bicol Region a few hundred kilometers southeast of Manila is already experiencing way too much flooding.
