In the contest post (that you weenied lmao), I predicted 14/9/3 and 139 ACE. So, I expect another weenie here.

1. I don’t see anything near 190 ACE this season. My original prog as stated in the contest thread was for ~139. I see no reason at all to increase that. 2. MH 6? That chance is tiny. I predicted 3 MH in the contest fwiw. 3. H 8 has a much better chance than MH 6 although it will be a challenge. Fwiw, I predicted 9 H in the contest, which is on life support right now. 4. Erin’s highest winds were 160 mph, not 160 knots. I’m assuming that’s a typo.

WeatherTiger update is out: opinions? https://weathertiger.substack.com/p/real-time-2025-atlantic-hurricane?utm_source=substack&utm_medium=email&utm_content=share Cycloneye of Storm 2K said this about this update: Down to 147 today, will probably dip into the 130-135 range by 9/10 unless we unexpectedly generate some ACE before then. More importantly U.S. ACE is falling as well, odds of 3+ U.S. hurricane landfalls now less than 25%. —————- My take: Seasons with 3+ H hits on the US are considered quite active for the US. They include these over the last 30 seasons (current active era): 2024, 20, 17, 08, 05, 04, 1999, 98 So, that’s 8 out of 30 or 27% with 3+ US H hits. Thus, he’s saying odds of 3+ have dropped to slightly lower than the normal chance of the active era. That seems to me like a reasonable drop considering the chance of the first prior to Sept 7th is low per models.

I’ll put this out here for potential discussion purposes. From met. Tony Brite: Edit: one caveat. Tony Brite is assuming 2025 will be just cold neutral ENSO. But per RONI, weak La Niña is actually favored. Also, my research suggests weak La Niña may actually be worse than cold neutral as far as the chance for a rough US hurricane season.

If we still have, say, 60 or less ACE by 9/30, then I’d agree that the chances for an active season ACEwise would be way down. However, that wouldn’t mean no chance when considering that 2024, 2020, and 2005 each had 75-82 ACE Oct 1st+. That would mean that 140 would still be technically attainable on the high end.

Bastardi is taking the opposite side of this, which is what I was referring to about warmer subtropics than tropics tending to stabilize the tropics, themselves: My take is that those subtropical waters will likely largely warm back up within a couple of weeks and make this cooling a forgotten thing by then.

What Derek Ortt is saying is debatable. Why? Because this has cooled a portion of the W subtropical region much more than the tropics, themselves. That arguably actually makes the W tropical Atlantic, itself, more favorable because this brings their anomalies closer together. Warmer subtropics than tropics tends to stabilize the tropics. Erin has reversed that to some extent. Edit: To make it more complicated, these storm related coolings have been reversing more quickly in recent years. So, we’ll see how long that subtropical region remains cool.

ACE is now at 37.14 with just a little more to be added from Fernand. This puts 2024 13th highest of the last 75 (83 percentile). The 1951-2024 avg through today is only 22. However, Invest 90L headed to the W Caribbean is now considered dead. Overall, the models including Euro Weeklies continue to look quite a bit quieter than climo through the 1st half of Sept. If that verifies, we’d quickly fall back down to at least NN ACE. From that point on, it would still remain to be seen whether or not PhiEaglesfan will be right about Erin being about the only big deal this season. I’ll be more than happy to give him kudos if he were to be right. But there’s still such a long way to go, especially in a cold ENSO season, which are often backended. In addition, recent seasons have been getting more backended, quite possibly related to GW.

Everything you said makes sense. Right here in my normally highly vulnerable location along with very high water table due to an insane nearly 17” of rainfall month to date (without a TC causing any of it obviously), I’m quite pleased about the current pattern. Thus I feel about as safe as I’m ever going to feel in late August when sometimes I’m on pins and needles wondering if I’m going to luck out. The big question though is whether an autumn-like pattern in much of August in the E US overall means that same pattern will likely continue through at least most of Sept. or do these anomalous fallish patterns tend to change or even reverse? There may not be a large enough dataset to analyze this.

The Euro ensemble, which for Invest 99L had gotten significantly more active 24 hours ago and then on the 0Z significantly less active than yesterday’s 12Z run, was very quiet on today’s 12Z with virtually nothing. Check out the difference between 12Z yesterday and 12Z today: 12Z yesterday at 216: somewhat active 12Z today at 192: nothing!

However, the 0Z Euro ens wasn’t nearly as active as the 12Z EE. The 6Z GEFS by my eyeballing has 5 (17%) TS+ members. So, not dead by any means but not all that active either.

Being a near east-coaster and also considering last year’s devaststing killer season, especially in NC, I sincerely love your optimism and hope the current pattern holds. One hit already this season is more than enough. Besides it’s fortunately not easy for the EC to be hit compared to the Gulf. Getting two EC TS+ hits in one year isn’t too common…~1/3 of years since 1995. However, regarding EC hits from storms that weren’t home-brew: -2022’s only hit wasn’t til 9/30 (Ian) -2018’s only hit wasn’t til 9/14 (Florence) -2016’s only hit other than TS Bonnie in May wasn't til 10/8 (Matthew) -2012’s only hit other than TS Beryl in May wasn't til 10/29 (Sandy) -2003’s only hit wasn’t til 9/18 (Isabel) -1999’s only H hit wasn’t til 9/15-6 (Floyd) -1989’s only hit wasn’t til 9/21-2 (Hugo) -1985’s worst hit by far wasn't til 9/26-7 (Gloria) -1950’s only hit wasn’t til 10/17 (King) -1947 had a rare 3 EC hits and they were all 9/17+ and only one was home-brew -1945 had one H hit and it wasn’t til 9/15 -1944’s worst H hit wasn’t til 9/14 -1941’s only hit wasn’t til 10/6 -1938’s only hit wasn’t til 9/21 -1928’s worst hit wasn’t til 9/16 -1898’s worst hit by far wasn’t til 10/2 So, these 16 years’ EC hits weren’t til 9/14+ and 50% weren’t til 9/21+.

After that re-drenching ~2” that fell yesterday evening, I’ve had as of 11PM only some on and off largely light rain since early this morning amounting to <0.1” here despite some nearby areas having heavier rains. That gets me to a ridiculous ~16.7” MTD! The mosquitos have been constantly partying this month like it was 1999. We’ll see how the rest of the night goes.

Yeah, I realized you were using 1991-2020 normals. But on that and even on the 2nd chart, it still looks to me like the bulk of the warming at Phil. has been since the late (or maybe mid) 1980s. Imagine cutting the 2nd chart off in 1987. If so, I don’t think any longterm warming trend would show. Instead, it appears to me like the line would be pretty flat. Do you see what I’m seeing?

Don, Am I looking at that graph right? Has virtually all of the warming at Phil been since the late 1980s?

Thanks for your replies! I’m all for open discussion of alternative ideas and that’s why I posted this and others from him. If the alternative idea appears to be plausible, it would probably be supported to an extent. OTOH, if not, it would likely be refuted. Also, I feel it’s important for others to be aware of what’s being spread to so many people (Weather Bell subs in this case) whether plausible or not. Thus, I expect to continue posting Dr. V stuff. In this case, Dr. V’s idea has been refuted several times here. That helps others like myself to be more knowledgeable about the doubtfulness of the plausibility of his idea. Not only that, I learned thanks to bdgwx about OMICS and its fraud. Today, JB posted this as a followup: I'm now going to incorporate this into my (forever) paper which is now in its second draft. The finished product will then be submitted to The International Journal of Environmental Sciences and Natural Resources, a peer-reviewed journal that has accepted other papers I've written in the past (in fact, they solicit me on a regular basis for contributions). That paper will then get passed on to Tom Nelson, EPA Administrator Lee Zeldin, and my Congressional Representative, Mike Haridopolis. That will hopefully get the geothermal hypothesis onto a higher plane. The bolded adds even more to my doubts about Dr. V. Why? I hate to bring politics into this, but Zeldin and Haridopolis are far righties, which imho has been the source of a lot of misinfo of all kinds, including CC. I’m saying that as a moderate independent as I’m not a liberal or a Democrat. Also, Thomas Nelson is the producer of “Climate The Movie: The Cold Truth”, which tries to minimize the significance of AGW. @donsutherland1

A hurricane is possible by Mon:Tropical Storm Fernand Discussion Number 1NWS National Hurricane Center Miami FL AL062025500 PM AST Sat Aug 23 2025The trough of low pressure (AL90) located a few hundred miles south-southeast of Bermuda has become better organized today. An Air Force Reserve Hurricane Hunter aircraft found a well-defined center during the past couple of hours, with a central pressure of about 1010 mb. The initial intensity is set to 35 kt, based on earlier scatterometer data which had a few believable tropical-storm-force wind vectors, and a Dvorak classification of 35 kt from TAFB.The initial motion is north or 010/13 kt. A north-northeastward motion is anticipated during the next couple of days with a slow increase in forward speed due to Fernand moving around the western periphery of the subtropical ridge. The storm will likely accelerate to the northeast thereafter as the system gets caught up in faster mid-latitude flow, well to the southeast of Newfoundland. The global models are in good agreement on this scenario, and the NHC forecast is on the eastern side of the guidance, closest to the HFIP Corrected- Consensus Model (HCCA).Fernand has about 48 hours over warm waters within generally light shear to intensify. There is a fair bit of mid-level dry air, however, which could hinder any rapid strengthening, so the intensity forecast will just show a more gradual increase in winds. All of the models peak the system as an upper-end tropical storm or category 1 hurricane, and the NHC forecast is just shy of a hurricane as a peak. After Monday, Fernand should weaken due to the influences of cooler waters and increasing shear, and the storm will likely become post-tropical in 3-4 days.

We’re apparently about to have TS Fernand a few hundred miles SSE of Bermuda. Also, Invest 99L is significantly more active on the 12Z Euro ens as it gets to the W Caribbean in ~a week. If it actually does develop there, watch out!

It appears they’re going right to TS Fernand based on this: AL, 06, 2025082318, , BEST, 0, 266N, 617W, 35, 1010, TS, 34, NEQ, 0, 90, 0, 0, 1015, 110, 90, 0, 0, L, 0, , 0, 0, FERNAND, S, 0, , 0, 0, 0, 0, genesis-num, 019, TRANSITIONED, alB02025 to al062025,

In addition to the 12Z Icon being still another of its runs developing this in the W Caribbean, the 12Z Euro ens is significantly more active:

This is the 1st time I can recall them going near 100% and them not designating it a TC at the next 6 hourly normal issuance time! If they’re waiting for recon, why not go 90%? Or why not issue a PTC advisory?

Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Sat Aug 23 2025 For the North Atlantic...Caribbean Sea and the Gulf of America: Southwestern Atlantic (AL90): Satellite images indicate that an area of low pressure has formed about 500 miles south-southeast of Bermuda, and the associated showers and thunderstorms continue to show signs of organization. A tropical depression is expected to form later today or tonight, with further intensification to a tropical storm likely on Sunday while the low moves northward over the southwestern Atlantic. An Air Force Reconnaissance aircraft is scheduled to investigate the low this afternoon. Interests in Bermuda should monitor the progress of this system as watches could be still required later today. For additional information, including gale warnings, please see High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...high...near 100 percent. * Formation chance through 7 days...high...near 100 percent.

Fwiw, the 12Z JMA very similarly to the Icon has a TD that forms on 8/29 in the NW Caribbean and moves NW toward the N. Yucatan:
