Future start

Just like the Atlantic, I'm starting this ahead of time too. Ryan1000 18:41, December 1, 2020 (UTC)

The GFS seems to start producing far out tropical cyclones for the EPAC. Another early start for the EPAC? It is far out like I said however.  ~ Roy25   Talk | Contributions   16:08, April 24, 2021 (UTC)

October

The EPac had an inactive September, let's see if it could catch up with the Atlantic in October. Like in the WPac, I am starting this section three days early (especially because there is an AOI which will likely be an October system if it forms).

AOI: 1,100 miles SE of Hilo, Hawaii

We have another AOI in the CPac. 10/30. Runner1001 (talk) 08:27, 1 October 2021 (UTC)

Still 10/30, hopefully this somehow forms... I want a CPac storm this year (though maybe that would come from invest 90E, which is still at 20/40). Jas (Anonymous 2.0) (talk) 10:13, 1 October 2021 (UTC)
Down a bit to 10/20. Jas (Anonymous 2.0) (talk) 20:02, 1 October 2021 (UTC)
Sorry Jas, but it looks like it is not happening for now. ~0/~0. Runner1001 (talk) 02:01, 2 October 2021 (UTC)

16E.NONAME

AOI: South of Mexico

Another AOI is up on the EPac TWO, but this only 0/20. Not likely to become much as it moves out to sea, unfortunately. Ryan1000 00:08, 5 October 2021 (UTC)

20/70 as of the latest update. Things have taken a dark turn and the GFS and CMC models make this sprout to a cat 2-4 hurricane and potentially slam Mexico's west coast a la Patricia/Willa. Only the ECMWF takes this out to sea. We will see what this storm will become in the future, and hopefully not another Patricia/Willa. ☁️ Nerd (Have a conversation) (Inputs) 20:47, 7 October 2021 (UTC)

30/80 now, and the models are really picking up on this storm now, while they didn’t show much before. The current area of formation seems to suggest that this will remain at sea, but if it comes closer to Mexico than expected then a landfall can’t be ruled out. Hopefully this won’t pull a repeat of Kenna, Patricia, Willa, etc. 4-day long cat 5’s like them have little warning before landfall. Ryan1000 23:45, 7 October 2021 (UTC)
Rapidly gaining organization. 70/90 now. The GFS still takes this into Mexico, but as a 952 mbar cat 3 instead of a 939 mbar cat 4. Now even the ECMWF takes this into Mexico, but weaker and much, much farther north. ☁️ Nerd (Have a conversation) (Inputs) 23:36, 8 October 2021 (UTC)

91E.INVEST

Still 70/90. Hopefully future Pamela won't be like the one she replaced (Patricia). Jas (Anonymous 2.0) (talk) 03:56, 9 October 2021 (UTC)

80/90. Runner1001 (talk) 11:57, 9 October 2021 (UTC)
90/90. Jas (Anonymous 2.0) (talk) 19:45, 9 October 2021 (UTC)

Most of the runs on tidbits now recurve this towards Mexico in a fashion similar to Kenna and Willa, at or just north of Puerto Vallarta. On top of that, almost all of the initial intensity projections are up to hurricane intensity, at least cat 1 or 2, before this makes landfall. But if this manages to pull some serious rapid intensification before landfall, then, as crazy as it sounds, this might even reach cat 5 just like Kenna, Patricia, and Willa. Hopefully it doesn’t though; like I said, storms like this may have very little warning before landfall if they do explode. Ryan1000 21:52, 9 October 2021 (UTC)

Tropical Depression Sixteen-E

Now a Tropical Depression and expected to be a Cat 2-3 Willa repeat on the first advisory. I don't like this storm, getting bad vibes from it. Plus the fact that the current forecast has Cabo San Lucas in the cone of uncertainty means Baja California Sur may get two bad hurricanes this year if push comes to shove. Has that ever happened before? ☁️ Nerd (Have a conversation) (Inputs) 14:22, 10 October 2021 (UTC)

Oh wow, already our first EPAC TCR of the 2021 season, and it's from Andres. No major changes it seems.  ~ Roy25   Talk | Contributions   15:32, July 01, 2021 (UTC) 

And it was done only 3 weeks after the last one from 2020 (Eta) was finished. That may be the closest gap between the last TCR from one year and the first TCR from the next that I've ever seen. Ryan1000 17:31, 4 July 2021 (UTC)

Less than a month after it dissipated, like 2018's Paul, Guillermo is out, completed yesterday. Not much to say though. Ryan1000 19:11, 16 August 2021 (UTC)

Felicia is out, completed 4 days ago. Pressure got buffed by 2 mbars, but her duration was cut a day short. Ryan1000 16:14, 13 September 2021 (UTC)

Marty is out, completed 3 days ago. And if he hadn't already had it hard enough as one of our yearly failures, he was actually nerfed more in reanalysis, by 2 mbars. Turns out McFly really is nothing but a little chicken... Ryan1000 06:01, 2 October 2021 (UTC)

Blanca is out, released today. No change to intensity but her duration got cut a day short at the end. Ryan1000 23:58, 4 October 2021 (UTC)
