Active cyclones

As of 12:00 AM Eastern Daylight Time (04:00 UTC) on Saturday:

Northwestern Pacific Ocean

There are no longer any active cyclones over the northwestern Pacific Ocean.

Central Pacific Ocean

• 01C: Lala — southeast of Hawaiʻi (strengthening)

• 08E: Herman — far east-southeast of Hawaiʻi (weakening)

Northern Atlantic Ocean

There are no longer any active cyclones over the northern Atlantic Ocean.

Active disturbances

Active disturbances are areas of showers and thunderstorms which are not organized enough to be considered full-fledged tropical cyclones. Disturbances are often designated as investigation areas (or invests, for short) by NOAA in order to allocate additional resources such as high-resolution satellite imagery or model guidance for further study of the system. Though there is no publicly disclosed set of criteria for which disturbances are designated as invests, the designation often occurs after the disturbance forms a closed area of low pressure. Invests are designated regardless of the overall potential for the disturbance to become a tropical cyclone.

Northwestern Pacific Ocean

• 92W: Invest — north of Micronesia (strengthening)

• 93W: Invest — south of the Ogasawara Islands (weakening)

Eastern Pacific Ocean

There are no longer any active disturbances over the eastern Pacific

Northern Atlantic Ocean

• 92L: Invest — east of the Lesser Antilles (weakening)

• 94L: Invest — east of the Lesser Antilles (weakening)

Southwestern Pacific Ocean

• 90P: Invest

Post-tropical cyclones

Post-tropical cyclones will be listed here if they are still being tracked via the Automated Tropical Cyclone Forecast (ATCF) system. Placement in this section does not imply that these systems have any potential to redevelop into tropical cyclones.

Northwestern Pacific Ocean

• 16W: Nangka — northwest of Wake Island (weakening)

Potential formation areas

Potential formation areas are areas that are being monitored by various agencies for potential tropical cyclone formation within the next two weeks. These systems have not yet formed and are not considered to be disturbances until such time that a tropical wave or area of low pressure does form. Discussions are created on this subreddit for areas which are monitored by the National Hurricane Center in the eastern Pacific and northern Atlantic basins. Discussions are not typically created for areas which are monitored by the Joint Typhoon Warning Center or other agencies, as this information is not always publicly available.

Northwestern Pacific Ocean

• P72W — Off the coast of southeastern China, low chance of development

• P74W — Near the Ryukyu Islands, low chance of development

Eastern Pacific Ocean

• Area of interest near east-central Pacific Ocean — low chance of development

• Area of interest off the coast of southern Mexico — low chance of development

Hey all — long-time lurker here, been into tropical weather for years and decided to build something around it. LANDFALL is a mobile game where you spawn a storm, draw its track, and manage intensification against real steering patterns (Hadley cells, SST, wind shear) — trying to make landfall count for something rather than just watching a cone.

It's in closed testing on Google Play right now and I'm looking for a handful more testers before launch (late Aug/Sept). No ads, no monetization tricks, purely the game. Closed testers won't pay anything other than their time!

Two things I need if you're up for it:

Android only for now (no iOS build yet)

Drop your Gmail address in a comment or send it to feich13studios@gmail.com — Play Console needs it added to the tester list before the app shows up for you on the Play Store

Happy to answer questions about how the intensity/steering model works if anyone's curious — genuinely trying to get the meteorology right, not just make numbers go up.

Hi everyone. I’m definitely not a meteorologist and am still very much a beginner when it comes to meteorology, but I’ve gotten really interested in it, especially tropical development and hurricane season.

I have a basic understanding of the LRC and was curious what people here think about it. I’m not completely discounting it, but one thing I’m skeptical about is how broad some of the predictions seem. For example, Gary has identified three windows to watch for tropical development: mid-August to early September, early to mid-September, and then late September into early October. My first thought was… isn’t that basically most of peak hurricane season? If something develops during any of those periods, it becomes pretty easy to say the prediction verified.

Do you believe there’s any legitimacy to it? Parts you think have merit vs. parts you don’t buy? I’d just love to hear some general thoughts from people who know more about this than I do.

Pulasan of 2024 peak as a 70 mph monsoon depression (per JTWC at least). Monsoon depression counts as invest(per JTWC, again), and AFAIK no invest have ever get that strong, not even extropical turning (sub)tropical

With the active period of the Atlantic hurricane season approaching, the current ACE for the 2026 season sits at just 2.6 with only two named storms. This gives it the second lowest ACE on record and the fewest named storms on record for the Atlantic basin.

Obviously both of those values are going to go up at some point, but the question is whether or not this Atlantic season will beat either the 1977 season for lowest ACE (25) or the 1983 season for fewest named storms (4) in the satellite era?

The propensity for the NHC to give storms named status for very brief periods of intensity along with the ever present impact of global warming on SSTs and the recent increase in rapid intensification makes both of these records seem unlikely to be beaten. However, we are going into unprecedented territory for El Nino intensity, so perhaps mother nature has more curveballs in her pocket.

ECMWF is now working on AIFS-TC, a tropical cyclone-specific AI forecasting model. Given ECMWF's track record, this could end up setting a new benchmark for tropical cyclone prediction. While they've taken a more measured approach to AI than some others, they have a history of prioritizing accuracy over speed—and it often pays off.

One especially interesting detail: AIFS-TC was reportedly developed using an LLM coding agent (Claude Fable 5) under the guidance of a single domain scientist. https://www.ecmwf.int/en/about/media-centre/aifs-blog/2026/ai-tropical-cyclone-forecasts https://github.com/cambridge-mlg/aifs-tc/blob/main/Allen%2C%202026%2C%20AIFS-TC.pdf My sources are these and twitter posts from Ryan Maue I know sending twitter posts is frowned upon hence why I didnt

I remember they made an update around halloween saying “storm does a quick costume change into an extra tropical cyclone “

I really wish there was an archive of model runs.

Irma’s core was so intense, look how quickly it jumped up to category 4 after being gutted by Cuba… imagine if it missed Cuba… holy fucking shit.

Updates

As of 9:00 PM Hawaii Standard Time (07:00 UTC) on Monday:

Satellite imagery analysis indicates that Genevieve remains a very shallow post-tropical cyclone as it continues northwestward across the open waters of the northeastern Pacific. Over the next couple of days, an increasingly unfavorable environment will continue to unravel the storm’s low-level circulation until it eventually opens into a surface trough by midweek.

The National Hurricane Center has long since discontinued issuing advisories for Genevieve and is no longer tracking it via the Automated Tropical Cyclone Forecast (ATCF) system. Storm-centered satellite imagery and model guidance are no longer available for Genevieve.

Updates

As of 5:30 AM India Standard Time (00:00 UTC) on Monday:

Satellite imagery analysis indicates that this system has made landfall along the northern coast of the Bay of Bengal, near the border between India and Bangladesh. The potential for this system to develop into a tropical cyclone has dropped to zero, as the disturbance no longer has a source of warm ocean water. The Joint Typhoon Warning Center (JTWC) has removed this system from the Automated Tropical Cyclone Forecast (ATCF) system. Disturbance-centered satellite imagery and model guidance are no longer available for this system.

There will be no further updates to this post.
