Fasten your seatbelts, peak of the hurricane season looks to be a bumpy one.

Question though, why wouldnt this pattern favour the EPAC? With sinking air over Africa and rising air mainly situated over the eastern pacific?

From my understanding we are even ahead of 2020’s pace in terms of ACE as of now

That signal seems to target the EPAC and W Carr, MDR looks unfavorable.

The time frame Eric has selected would favor the eastern Pacific more yeah. However, the general idea of an uptick in activity after a brief hiatus following Henri remains because you can bet money that convective pulse will travel eastward with time and eventually favor an uptick in Atlantic activity once the eastern Pacific takes a nap, assuming the shear relaxes. Timeframe for more tropical activity looking to be first or second week of September, models FINALLY starting to pick up on this too. I'd be concerned if they weren't at this point.

Oh ****. I wonder if the MJO comes out of the circle back in 8 or 1?

Maybe it's just me, but it seems those posts are significantly down this year from pretty much every other year I've been on the site (+/- 2002).


Yeah I wouldn't doubt you're wrong. I've only seen the posts from last year and this year so I have limited knowledge regarding that, though I may have some idea on how far it can get based on others references back to 2017. Perhaps I should read back. :lol:

Personally I felt the month-long break of tropical cyclogenesis brought about a little surge of them similar to but less than last year's quantity > quality posts. Regardless just like then they'll probably phase out over time as we reach the first and second climatological peaks respectively.


Haha yeah, it was intolerable at times with several posters reaching for anything to fit their preseason agendas. This included both wish and down casters.

Looks to be the entrance of a favorable CCKW on steroids that moves through

The eastern MDR does, but that Kelvin Wave will propagate westward as September goes on, and waves will find favorable conditions in the western half of the MDR.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

The Kelvin Wave is passing through is not staying put, also climatoligy and a developing La Nina along with -PDO does not favor much of the activity to be in the EPAC.

Ummmmmm.....okay then, this is happening :eek:
SST's in the eastern MDR :uarrow: If this trend holds or amplifies in the coming weeks with that monster CCKW coming through and everything lines up right, could see some of those long trackers we've all been waiting for come second week of September. I know Andy Hazelton mentioned that the EPS is going nuts with Cabo Verde activity in a few weeks in reply to Eric's post listed above. This is probably a powerful factor in why.

Even if it doesn't come of the circle the Kelvin Wave would be in control, I can see it coming out at least on phase 1 & 2 which still favors the Atlantic basin for activity during the peak of the seaon.

Phases 1, 2 and 3 would be extra proverbial fuel for the fire.
