Dissipated 28W (Western Pacific) (South of Japan)

3 Upvotes

Storm overview

This discussion is for Tropical Depression Twenty-eight (28W), which is active over the western Pacific.

A tropical depression remains active a few hundred kilometers southeast of Iōto in Japan’s Ogasawara Islands. The depression has not undergone any significant changes in strength or structure over the past several hours; its low-level center remains exposed and only a few isolated bursts of deep convection continue to flare up to the southwest. This system continues to move toward the west-northwest under the steering influence of a deep-layered subtropical ridge positioned to the northeast. Upper-level convergence associated with a trough positioned directly above the depression is suppressing any potential for outflow development, preventing the depression from developing in an otherwise highly favorable environment.

This system is likely to stop producing persistent thunderstorm activity and will degenerate into a remnant low as it passes well to the south of Iōto by the end of the week.

Official information

Japan Meteorological Agency

Though the JMA does classify this system as a tropical depression on its surface analysis and prognosis charts, it has not initiated issuing tropical cyclone warnings for it.

Discussion Trying to learn ..... why did Simon deviate so far outside the cone?

35 Upvotes

At the 3PM CST update on October 10th, the NHC update indicated that Simon would move laterally from 104.8W to 105.2W over the ensuing 48 hours. 

INIT  10/2100Z 17.6N 104.8W  130 KT 150 MPH
 12H  11/0600Z 18.3N 104.9W  130 KT 150 MPH
 24H  11/1800Z 19.4N 105.1W  110 KT 125 MPH
 36H  12/0600Z 20.8N 105.2W   70 KT  80 MPH...INLAND
 48H  12/1800Z 21.9N 105.2W   45 KT  50 MPH...INLAND

At the 3PM CST update on Oct 12th, Simon was actually located at 106.8W

INIT  12/2100Z 20.2N 106.8W   85 KT 100 MPH

Instead of a 0.4 degree shift in longitude, Simon moved 2.0 degrees.

The latitude miss was 1.7 degrees (21.9N forecast vs 20.2N actual)

These kinds of deviations from forecast are quite unusual. Something took place which the forecasters didn't anticipate.

What happened that forecasters didn't anticipate? What do we learn from this?

Seasonal Discussion · EPAC ACE record broken Counting down to the EPAC ACE Record .....

18 Upvotes

The EPAC ACE record of 319.26 from 2018 could fall in the next couple of days.

The most recent update has 2026 EPAC ACE at 307.9.

Rachel has maybe 1.5 ACE left in the tank leaving us 10 shy and if Simon holds to the forecast or exceeds it, then it seems that's enough to get 2026 over the top.

The strong El Nino stereotype is emerging in the statistics.

Official discussion Moderation feedback and upcoming changes to the subreddit

96 Upvotes

Good afternoon!

I want to give you all a platform for sharing your feedback of the subreddit and how I have been doing as a moderator. I am far more interested in negative feedback. I appreciate the compliments, but I really want to know what annoys you about the subreddit (or me as a moderator personally) and what needs to be fixed going forward.

Here are some things that are already in the works or have already been implemented:

No more advisory junk

Posts for active disturbances and cyclones will no longer feature discussions, observational data, or advisory charts. I have been updating these manually by myself for years and it is clear that I am unable to update them in a timely enough manner for the information to even matter. Please use the links provided in each post to get the information you need form more authoritative sources.

  • Clarification: If I can ever get around to learning how to make this an automated process, these features may return to posts. If you are interested in becoming a moderator and can demonstrate that you know enough about the Reddit API and development tools to create an automated process for this, please reply to the stickied comment. I'd love to discuss this with you in the future.

No more basin filtering

Before the new version of Reddit became active, we were able to create a link flair filter which allowed users to filter the subreddit based on cyclone basin. You could click a link in the sidebar which would only show posts tagged with Atlantic, Pacific, Indian, etc. This functionality no longer works and therefore, the link flairs have been simplified and the filter buttons have been removed from the sidebar.

  • Clarification: These filters used a URL trick to hide posts which did not match the specified CSS class of the link flair. These filters only worked on the old version of the desktop website and never worked in the app or in third-party tools. Once the URL trick was depreciated, the filters no longer actually worked, so they were removed.

Looser posting requirements

I will be loosening up the "soft restricted" mode, allowing more posts to hit the front page of the subreddit without needing to be reviewed by a moderator first. There are only two active mods right now and sometimes posts sit in the queue for more than a day. Often, users will delete their posts before I have the chance to review them. If new posts violate the rules, please report them so that I can remove them.

  • Clarification: I do not intend to open the floodgates to all content. There are existing fallback filters which should catch rule-violating content and content from banned sources. I will be working to improve these filters to ensure that unwanted content does not reach the subreddit. I will also be working on an expanded approved users list so that content by trusted users does not require moderator approval.

No more live threads

Many people have been asking where the Live Threads have gone. For one, there are not enough moderators or volunteers to help maintain Live Threads. Second, Reddit does not officially support Live Threads anymore. It is a feature of the old version of the website which has not been regularly maintained in years.

Moderator applications

Once Hurricane Isaias makes landfall and dissipates, I will be opening up moderator applications. I really need to step away from the day-to-day operations of this subreddit and let it flourish on its own, but I will need help doing that. The new version of Reddit has a moderator application function. I will be reviewing that over the weekend and making it active sometime next week. I will post a new discussion for that purpose to the subreddit.

Update

Status of the Discord

Although I am one of the administrators of the TropicalWeather Discord server, the server is no longer officially affiliated with the subreddit.

Preserving the style of the subreddit

I also want to clarify that I do not have any personal beef with r/hurricane. Both r/hurricane and r/tropicalweather have completely different approaches to sharing this important information and I want to maintain that distinction. I will continue to resist calls to make our subreddit more like theirs and I will continue to discourage people from insisting that their subreddit needs to be more like hours.

NOLO made its debut at 117W longitude and has now passed 150E longitude. That's more than 25% of the Earth's longitudinal span. It's possible that this is a global tropical cyclone record for longitude traversed.

Discussion Isaias, model by model: physics vs. statistical vs. AI intensity forecasts from NHC’s public data, plus what has already verified.

35 Upvotes

Hi folks, I’m a computational engineer with a background in fluid dynamics. Isaias is forecast to make landfall near Mobile Bay, where my parents live. My dad is recovering from open-heart surgery, so I’m driving down to do the heavy lifting and chainsaw work he shouldn’t be doing.

Before I left, I wanted to understand why the intensity guidance disagrees. Physics-based, statistical and AI models are all forecasting this storm, and it’s an interesting test of how they compare. So I built a page from NHC’s public model and best-track data:

https://lukemcculloch.github.io/static_hurricane_info_site/

What it shows, as of the 12Z Thu cycle:

Every number is reproducible from scripts in the repo (bash/awk on NOAA’s files), and the methods page lists the caveats. The page updates each cycle and archives the earlier versions, so the pre-landfall versions stay on record. After landfall I’ll score each aid against the best track.

I am in a hurry to get on the road, so I generated this, directing Claude Opeus 5.5 medium while I was packing up. I also used it to help me remember what supplies to bring.

emphasis: (Built with help from Claude for the coding and data processing.)
(I hope you guys don't tear me to ribbons, but one must let the chips fall where they may, heh)

This is not a forecast. Use NHC and your local NWS office for decisions. Corrections are welcome here or as GitHub issues.

Stay safe, everyone on the Gulf Coast.

Notes: this site will update when I can stop in to get online with the latest data, if I feel I have time.

▼ Remnant Low | 30 knots (35 mph) | 1006 mbar Simon (20E — Eastern Pacific) (South of Mexico)

10 Upvotes

Storm overview

This discussion is for Tropical Storm Simon (20E), which is active over the eastern Pacific.

Satellite imagery analysis indicates that Simon continues to weaken as it lingers off the coast of western Mexico. The storm’s convective structure is incredibly compact, with tropical storm-force winds extending only 55 kilometers (35 miles) from the storm’s center. The storm is moving slowly southwestward as it remains caught in a weak steering environment between a mid-level ridge positioned to the southwest and a mid-level ridge positioned to the northeast. Environmental conditions will remain generally favorable for the next day or so, but southwesterly vertical wind shear is likely to increase and allow dry air to penetrate Simon’s inner core.

Simon will continue to meander off the coast of Mexico through Friday, before a deep-layer cut-off low moves southward across California and pulls the storm northwestward. The storm is expected to pass just offshore to the west of the Baja California peninsula and degenerate into a remnant low by Sunday evening as it moves over unfavorably cool waters and into a drier and more stable environment. There remains some degree of uncertainty regarding exactly when Simon will start to move again and thus, it remains too early to determine the timing and extent of any potential impacts to Baja California over the next few days.

Upgraded | See Isaias post for details 09L (Northern Atlantic) (Gulf of Mexico)

74 Upvotes

Storm overview

This discussion for Tropical Depression Nine (09L), which is active over the southwestern Gulf of Mexico.

A trough of low pressure which formed over the Bay of Campeche over the weekend quickly organized on Monday morning, developing a closed low-level circulation and more organized convection. This led the National Hurricane Center (NHC) to upgrade the disturbance to a tropical depression and initiate issuing advisories. The depression is currently in a quasi-stationary state, as it remains embedded within a very weak steering environment. However, over the next couple of days, a mid-level ridge positioned over the western Atlantic will build across the Gulf of Mexico, generating a southerly steering flow which will cause the storm to move northward or northeastward through the end of the week.

Environmental conditions are not particularly supportive of development, as very warm sea-surface temperatures and abundant mid-level moisture are offset by moderate southerly vertical wind shear and weak upper-level divergence. Still, this system appears to have a very compact convective structure, which will likely allow it to remain intact far longer than the environment would otherwise allow. Because of this, the National Hurricane Center (NHC) forecast calls for the depression to strengthen into a tropical storm later this evening and further reach hurricane intensity by Thursday. The depression may even be close to Category 2 hurricane intensity before making landfall at the end of the week.

Impacts overview

Mexico

This system will drift eastward to east-northeastward before turning northward later this week. Because of this, the Yucatan Peninsula will likely see the earliest impacts from this system. Heavy rain is possible across portions of the coast along the Bay of Campeche, but particularly over the Yucatan Peninsula, where 2 to 4 inches are possible through Thursday. Additionally, gusty winds will be possible across portions of the Yucatan Peninsula on Thursday, but it remains too early to determine whether tropical storm conditions will be possible.

United States

The threat of heavy rain and flash flooding will spread northward toward the Gulf Coast of the United States later in the week. Rainfall totals will range from 3 to 6 inches across the central Gulf Coast, from southeastern Louisiana to the Florida Panhandle. Localized totals may reach as high as 10 inches. Flash flooding, urban flooding, and isolated river flooding, will be possible as this system nears the coast from the south and makes landfall at the end of the week. Additionally, strong winds will be possible, but it remains too early to determine the exact timing, location, and extent of tropical storm or hurricane conditions. No watches or warnings have been issued for the Gulf Coast at this time.

iOS App: https://apps.apple.com/us/app/hurricane-recon/id6777447589

I made an iOS app for tracking Reconnaissance Data for Tropical Storms and Hurricanes. I made it because following recon during a storm meant juggling tabs.

On the app you can track Air Force Hurticane Hunter and NOAA planned Flights and their locations. It's easy to see forecast tracks. This puts it all on one map:

Live recon tracks for aircraft currently flying, colored by HDOB wind speed

NHC forecast track and cone, past track colored by intensity, and invests

IR satellite, radar and model guidance layers

Tasked fixes from the Plan of the Day, plus an Ops Board listing each tasked flight's takeoff and fix times and what's airborne now.

Right now you can watch AF304 working Isaias in the southwestern Gulf, with NOAA 43 scheduled for a tail Doppler radar mission later today.

It's a hobby project, so I'd really like feedback on what's missing or what's wrong. Obviously, rely on the NHC and your local officials for decisions; this is just a way to follow along.

Discussion moved to new post 92L (Invest — Northern Atlantic) (Southern Gulf of Mexico)

73 Upvotes

Disturbance overview

This discussion is for a disturbance which is active over the southern Gulf of Mexico.

A trough of low pressure situated over the southwestern Gulf of Mexico continues to produce disorganized showers and thunderstorms this morning. Though the disturbance still lacks a closed low-level circulation, it has become better organized and if this trend continues, it will become a tropical depression later today. The disturbance is meandering southward as the steering environment remains very weak, but over the next couple of days, it will begin to drift northward to northeastward as a mid-level ridge over the western Atlantic Ocean builds across the Gulf of Mexico.

This system is expected to reach the Gulf Coast of the United States by the end of the week; however, it remains too early to determine the exact timing, location, or extent of any potential impacts to Louisiana, Mississippi, Alabama, or the Florida Panhandle. Regardless of development, this system could bring prolonged heavy rainfall to the region at the end of the week and over the upcoming weekend. Residents in this area should continue to closely monitor this system as it develops.
