Who knows, the models could be underdoing the intensity as we know they are not that reliable this far out plus it is somewhat more defined on the 12Z Euro as compared to the 00Z:

Euro:

Based on the 12Z model consensus, my biggest concern for at least the next two weeks for the CONUS is for the period August 13-17, when the Bermuda high/WAR looks strongest, which may make it hard for a safe recurve. During that period, the model/ensemble consensus is suggesting that what's now coming off Africa will merge with energy/moisture now near 30-35W and likely move quite far west in the MDR at a very much up in the air strength (could end up being just a vigorous tropical wave). Bears watching.

Meehh, doesn’t mean anything what operationals are saying this far out. Over 240 hours out, operationals are just about useless.

18z GEFS: backing off from the northern tracks shown in 3 previous runs. One member does make it into gulf towards TX/Mex border.

GFS showing crickets through 8/21, if we are getting to 18/9/4 I think we need to be seeing something in the long range modeling now.

Agree. The real peak begins on the 15th and as you say crickets. Dont think it will be like 2022 when there were 0 formations in this month, but the models better start to show solid things, not only waves.

Captain Barbossa's Tropical Cyclone Timeline:

1. June 1st: Everyone is excited about the upcoming season. Many are anticipating upcoming action later in the month, but most know that the real action will most likely start in August.

2. July 1st: One or two TCs manage to form in June. Many complain about how weak and disorganized the cyclones are.

3. July 15th: Lots of SAL is present in the Atlantic basin. However, most people are not surprised by this, as they were expecting it.

4. August 1st: Atlantic is still slow. Dry, stable air is present in the tropics. However, models are beginning to suggest things will be changing within a few weeks.

5. August 15th: Models show nothing in the near-future. Many are becoming skeptical about the season amounting to anything significant.

6. August 23rd: There are multiple invests in the Atlantic and conditions are rapidly beginning to change. The models begin to show cyclogenesis. Many quickly change their minds about a quieter season.

7. August 24th: Some experts continue to doubt signs of the Atlantic awakening. These experts issue outlooks that support original ideas of a quieter season.

8. August 31st: There is now at least one active TC. There is a potential that at least one TC could become a hurricane. Many people appear shocked by the increased activity.

9. September 30th: Several TCs have already formed and dissipated. A few who suggested that the season would be quiet now state that they always knew the Atlantic would spring to life.

10. November 30th: The last storm probably has dissipated by this point. Many look back at the season and state that they are surprised with the outcome.

Normal year, this timeline applies. El Nino year likely slowing down development in September and August was expected to be more active than normal. Maybe it will, but not according to the long range models today through 8/21. We will see soon enough!

I don't understand why people talk as if September 1-30 will all be shut down, when September is climotologically still the busiest month of the season; and that the Atlantic will be dead if it doesn't wake up in early and mid-August, when climatologically this period is still significantly less active than the "real" peak season that generally begins on August 20, and feels more like July.

Several El Nino years - even those that ended up with inactive Atlantic seasons - had at least appreciable September activity. 1997, which had no August named storms, had a Cat 3 CV storm (Erika) in September. Both 2014 and 2015 had Cat 4s in October (Gonzalo and Joaquin). Don't even get me started on September 2004.

With the atmosphere resembling the opposite of an El Nino until now, I'm not convinced that it will couple so quickly that we'll see full-blown Nino shear in the Atlantic in just a month. But it could be just me.

I'm getting sick and tired of seeing that season cancel timeline in every thread. It was funny 2 years ago.

We're in an el nino year, forecasts are through the roof. I think most will bust, but hey, it's fun to watch and talk about. If you want to discuss it that's great, but if you find yourself doing a copy paste please refrain.

First time I’ve seen it this year, and I think it pretty aptly describes what’s been going on in the dialogue, especially on social media. This El Niño isn’t like most others. The background state is odd, the atmospheric response is delayed, and sst’s are above normal almost everywhere. I’m more sick and tired of people asserting they know how this season is going to go when there are few if any analogs that even experts can agree on.

I like it. True, it probably doesn’t necessarily apply to every season but it does seem true of a lot of them. Plus I don’t think it’s technically meant to be funny, but more informative (and the yearly reminders don’t hurt!).

However the rare August hurricane strike have been particularly bad. Andrew and Charlie are 2 modern era examples.

Looks like the ensembles woke up.thos morning. We will see if this will continue for many more runs or just a hiccup.

Regardless the energy from the waves currently in the MDR will likely be near S. Florida late next weekend so we may get some increased rain chances. Fortunately the CMC is no longer aggressively developing something next week.
