Re: 2021 EPAC Season
I really hope there is a recurve system that could bring rain for my area whitout making landfall in a populous region and without causing major damage, it's September and so far the year have been dry for me, its not funny when the city has water deficit. The Atlantic doesn't seem to be able to send a system near me and with the time to do it closing (as we near October), EPAC is my last hope

Re: 2021 EPAC Season
The fact the GFS and ECMWF are completely dead despite an incoming CCKW is somewhat alarming. Yes, meteorology!=modelology but it seems the base state has become much less favorable than the reasonably impressive start of the season. Then again this happens on occasion when MJO gets stuck over the IO for a while and I’m not yet quite sure why.

Re: 2021 EPAC Season
Ok that's something I suppose though really far west. Environment doesn't look too favorable with no ULAC present however.

Re: 2021 EPAC Season
Euro been showing it for the past 4 runs. Never really gets going. But maybe if there's a strong enough ridge it'll be possible.

Re: 2021 EPAC Season
it's been looking good. JTWC will take care of it but no mention from the CPHC.

Re: 2021 EPAC Season
0z GFS weaker because it moves the vorticity north but honestly this is a good upper environment.

Re: 2021 EPAC Season
An area of low pressure could form several hundred miles southwest
of the southern tip of the Baja California peninsula in a few days.
Gradual development of the system will be possible while it moves
generally northwestward at 10 to 15 mph through the middle of next
week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
