Tropical 2024 Tropical Thread Reboot

There's Francine and her cousin Gordon on the Bus and ETA in the Conus 16 days: Aug 30.
See Lex, you don't even need a computer Model: Satellite will do you just as well:

We will see. The pattern is perfect for a wave to make it across but the GFS says no to waves up to hour 300.

At 324 its peak season and this is JB's 100% perfect pattern. With that huge high over the NE US and NW ATL there SHOULD be lowering pressures to the south in the SW ATL, but there isnt. Something is wrong and things just cant get started. Yes, maybe all of a sudden the models will light up with activity.

You just arent going to see this very often 1031mb high in the NW ATL but now pressures are above normal everywhere

One thing to watch is the Euro does have a wave north of the islands at 216 but will the high build in over top?

This article is a little dated but it helps explain why tropical development has been so hard to come by in what should be and still might be perfect conditions for an above normal hurricane season. Cut the Saharan dust out of the equation and get the MJO phases to cooperate and then business might pick up in the Atlantic.

Yeah give it a couple weeks. If we're still dead at the end of the month clearly something is off

I would be shocked if we are dead
 
Based on model/NHC progs and considering how warm the SSTs are way up above Bermuda, it is a reasonable possibility that Ernesto could bring 2024 season to date ACE to ~65 as of Aug 20th. If 2024 is at 65 then, it would still be in 6th place, just one back of the 5th place as of Aug 8th:

As of Aug 8th, 2024 was at 41. That was in 5th behind only 2005 (74), 1933 (54), 1926 (47), and 1916 (42).

If 2024 has 65 as of Aug 20th, it appears it would then still be in 6th behind only 2005 (~85), 1933 (~80), 1899 (~77), 1886 (~75), and 1893 (67).

One would think that keeping this in mind would stop any season cancel declarations.

After the recent impressive display of activity wouldn't it seem counterintuitive to expect it to suddenly fall off a cliff?

Think the little wave that's getting ready to come off Africa in about 24-36 hours has a shot. Imbedded in a pretty good moist envelope per water vapor satellite. Time will tell.
 
Another one who agrees with me that the MT is configured wrong



He does say it might change in late Aug. Until it does storm formation will be sporadic




Just way too far north. The Low pressures north of the CV Islands is unworkable

Good Ole JB said early last week Labor Day weekend in SE could have another storm to deal with, we shall see
 
JB says its possible for a storm to form off the coast in 10 days. Will need something to get the season moving



With Ernesto, the season continues to move with not only high ACE but also with a very high % of that ACE W of 60W. It currently is already near 85%. Assuming we get to near 65 as of Aug 20th, the % of ACE for season to date would still then be ~85% with 55 of 65 ACE W of 60W, which could rank as high as 5th highest:

Projected Aug 20 ACE W of 60W:
1) 2005: 78 of 85 (92%)
2) 1886: 69 of 75 (92%)
3) 1899: 69 of 77 (90%)
4) 1933: 63 of 80 (79%)
5) 2024: 55 of 65 (85%)

1893 is way back with only 41 of 67 (61%) W of 60W


The following graph shows how high 2024’s ACE was as of Aug 8th (in yellow):

If the preseason forecasts had been around 13/7/3 then i would agree this is an active season. They were more like 24/12/6 so its inactive compared to forecasts. Webb is joining me and others now noticing the lack of Wave development.


 
By the way, having 65 ACE as of 8/20 would be vs a 1991-2020 avg of only 18.9:

If we get 24 ACE during just 8/13-20, that would be a whopping 4 times the 1991-2020 normal of only a mere 6 during that period! And 1991-2020 was during a very active era!

If the EAST Pac gets active again it will delay the ATL even longer. There are some signs Sept will be active.

At 18z the GFS is going nuts again in the East Pac. I was afraid the ATL was taking so long to get started that the East Pac would come back to life. IF this happens its really hard to see how the ATL gets active but i guess its happened before
