This will help the PMM a little bit. Help warm up the lacking 18N-20N SST's.

12z GFS had a fun fantasy run, with a hurricane moving all the way up the Gulf of California. Won't happen though.

Yeah some waning support from the EPS for this system. I think we'll be entering the long awaited lull of EPAC activity soon with the Atlantic going off.

Some possible areas of interest on the 12z Euro:
![Image](https://i.imgur.com/zYJsWdw.png)
Minimal EPS support though. Need something cranking soon to get ACE back up to Climo. We're about to fall below climo despite the high number of systems and decent amount of hurricanes.

Next window for development isn’t really until September 20 or so. Not falling for anything before then.
Btw -PDO is deepening though horseshoe remains warm.

12z Euro continues with what appears to be a legit AOI in about a week:

Has 40-45% EPS support in 10 days.

12z GFS back to the EPAC bias. However we should see at least one named storm.

12z Euro now showing two robust disturbances with good EPS support for both:

There will be a CCKW moving into the EPAC from September 6 -> 13.

45 day EPS. I guess there’s a small window for something around September 10 but not as aggressive as the GFS suggests. Late September/early October remains the next window for significant activity.

Not trusting the Br*ts. 60 hours seems to soon for genesis though decent agreement with that and GFS for track.

Development is possible. The ECMWF shows a small short-lived rising air cell over the east Pacific from September 6 to 12. Something could form from that.
