Future start

The 2019 Pacific hurricane season is coming up, and the betting pools are up. I'll make some predictions for this season later, but if any of you guys have pre-season predictions, feel free to post them below. Ryan1000 03:56, November 20, 2018 (UTC)

CPHC will be merging their site to the NHC's in May. This should make finding advisories for CPAC storms even easier. Won't change the pace of CPHC TCRs though. Here's some other changes for this season.--Isaac829E-Mail 04:40, March 22, 2019 (UTC)

...and the CPHC site is gone.--Isaac829E-Mail 20:24, May 13, 2019 (UTC)

The 2019 Pacific hurricane season has now officially begun! Sandy156 :) 00:00, May 15, 2019 (UTC)

Pre-season-May

AOI: In the Open Pacific

What on Earth? An invest suddenly popped up out of nowhere. 30/50 chance of formation and has good model support. We could be seeing history here. - PORYGONAL 20:32, January 3, 2019 (UTC)

Woah, wasn't expecting that. Looks like GFS takes it up to 50 mph/1000 mb, which means we can see a record for the earliest named storm in the East Pacific's history. Guess I'll cheer Alvin on, lol. I just hope that this isn't a sign for what's to come later in the season, though... TG 2019 21:12, January 3, 2019 (UTC)

What is this I don't even...well I'll be damned, I never thought I would ever see an AOI in the EPac proper with a good chance of forming in January, of all times of year. There has never been a storm to form this early in the EPac proper since reliable data began in 1949, and only Ekeka of 1992 and Pali 3 years ago (which was arguably a continuation of 2015's extreme activity) did so east of the dateline in the CPac. If this becomes Alvin, I'll be overjoyed. Far out to sea, fishspinner, and unique time of year, what's not to like? Also, slightly off-topic, but if you guys want to vote on the nominees for the Hurricane Hall of Fame for 2019, all basins are open. This might prompt some more activity on the forums for that, seeing as how the SHem storms and Pabuk aren't getting much attention. Ryan1000 02:54, January 4, 2019 (UTC)

I know right, I have never seen an AOI in the EPac proper in January before... I was really shocked to see this. a lot of records will be broken if this forms, holy sh!t. And if it becomes subtropical, it might be the first EPac proper subtropical storm ever recorded (I think?). I'm totally rooting for Alvin to come out of this. And about the HOF, I hope to vote this weekend. ~ Steve 🎉 2019is here!🎆 05:19, January 4, 2019 (UTC)

I've been checking the NHC webpage out of habit for a while now, didn't think i'd actually see something pop up. C'mon Alvin, I believe in you! Send Help Please (talk) 12:53, January 4, 2019 (UTC)

Chances have dropped for this, now 30/30. TG 2019 21:00, January 4, 2019 (UTC)

Dropped to 0/0. Looks like the long wait begins once again (assuming it doesn't make a comeback, which seems unlikely.  ~ Roy25   It's 2019!!! | 🎉   02:48, January 06, 2019 (UTC) 

I guess this is gone for good without becoming Alvin. The extremely long wait until May starts up again. 😕 It looks like it's at the southernmost part of a system currently striking my area. ~ Steve 🎉 2019is here!🎆 07:36, January 6, 2019 (UTC)

Well, that was funny. Shame it didn’t become named. Leeboy100^Hello! 00:31, January 17, 2019 (UTC)

91E.INVEST

AOI: South of Mexico

The first AOI in the EPac’s season boundaries, this large area of disturbed weather appears in the TWO some several hundred miles south of Mexico. It has a 10/20 chance of formation as of now. The GFS model shows it becoming a 1009 mbar storm before dying off. Sandy156 :) 00:26, May 16, 2019 (UTC)

91E.INVEST

Invested according to TropicalTidbits. Still 10/20. ~ KN2731 {talk} 15:54, May 16, 2019 (UTC)

Dr. Masters made a new blog post discussing 91E (so apparently the above AOI back in January was 90E, unless the NHC made a mistake skipping over invest numbers like they did with Beryl of last year). In any instance, SST's near Mexico are cooler than average as of May 14, which, if it persists later on, would could surpress stronger TC's near Mexico this season. However, SST's are warmer than usual near Hawaii, so the people there may need to watch out for a potential hurricane later this season, especially after the close call they got with Lane last year (which still caused heavy flooding even without making landfall). This AOI shouldn't become anything serious, but it could get the EPac going with another May storm, and the Atlantic may still have a chance to spin up a May storm over the next two weeks before the AHS begins on June 1. While it's not too likely, it would make for a record 5th consecutive early start for the Atlantic, which would be nice to see. Ryan1000 16:17, May 16, 2019 (UTC)

Down to 0/20 and off the 2-day TWO as of 11:00 am PDT. Sandy156 :) 23:14, May 16, 2019 (UTC)

Up to 0/30 as of the latest TWO. Sandy156 :) 23:23, May 16, 2019 (UTC)

Now 10/40 and back up into the 2-day TWO. This might have a chance of becoming Alvin or a sad tropical depression for the next few days. Sandy156 :) 17:47, May 18, 2019 (UTC)

Nevermind, it’s gradually dying off. It’s now 10/30 in the latest TWO. Sandy156 :) 07:10, May 19, 2019 (UTC)

Although it's only at 0/20 for now, it could become Alvin later in the week as it moves west-northwest away from the coast of southern Mexico. Ryan1000 19:28, May 20, 2019 (UTC)

0/30 now. Beatissima (talk) 23:58, May 20, 2019 (UTC)

0/40. Beatissima (talk) 06:35, May 21, 2019 (UTC)

10/50, looks like this might become Alvin after all.... Ryan1000 11:45, May 21, 2019 (UTC)

Now 20/50 per latest TWO. Sandy156 :) 05:18, May 22, 2019 (UTC)

30/50 as it approaches Nic. Some models have it cross into the Atlantic while others have it stay in the basin. Sandy156 :) 05:21, May 23, 2019 (UTC)

Decreased to 20/40 as the invest hits in between Nicaragua and Honduras. Sandy156 :) 14:30, May 23, 2019 (UTC)

10/30. Dr. Masters said there's a possibility that this AOI (or another central amerigan gyre/CAG, for short) could move into the Atlantic in about a week and become TS Barry if 91E doesn't move offshore in his latest blog post. Michael, for perspective, also developed from a CAG last October, though the Atlantic probably won't get a storm as strong as him in June. In that post he also mentions that the Atlantic has a 30% chance of being either above or below-normal, with a 40% chance of average, though nothing can be ruled out in these early stages. We're currently in a weak El Nino but expected to transition into ENSO-neutral later this year. The EPac, however, is expected to have another busy season, with 15-22 named storms, 8-13 hurricanes, and 4-8 majors, i.e. a 70% chance of being above-average this year. Also, with the previous post that he mentioned with SST's being warmer than usual near Hawaii (but cooler than average near Mexico), they may need to watch out later this year. Ryan1000 19:23, May 23, 2019 (UTC)

Now it’s 30/40. Sandy156 :) 18:03, May 24, 2019 (UTC)

Down to 10/30 and conditions are expected to be unfavorable for further development. For an AOI that's been spinning around for the past 10 days, one would've expected it to become something by now, but I guess not... Ryan1000 09:15, May 26, 2019 (UTC)

Back to 10/20, not going to form if unfavorable conditions persist. Sandy156 :) 17:44, May 26, 2019 (UTC)

Down to 10/10. Alvin might need to wait a little longer. Anonymous 2.0 (talk) 15:27, May 27, 2019 (UTC)

And now down to 0/0. Looks like this won't become Alvin after all; also, as a side note, the NHC put down the CPac as an area for TCR's on their site, so we'll include them at the end of this year, since now they'll come out faster. Ryan1000 10:12, May 29, 2019 (UTC)

The disturbance is gone and off the TWO. Sandy156 :) 17:34, May 29, 2019 (UTC)

92E.INVEST

AOI: South of Mexico

Another disturbance formed in the EPac just a few hundred miles south from Mexico. It’s at 10/20. The disturbance will go northeast where it might even hit Southeast Mexico or Guatemala. Sandy156 :) 18:06, May 28, 2019 (UTC)

92E.INVEST

Invested and up to 20/20. Sandy156 :) 01:01, May 30, 2019 (UTC)

Down to 0/0. This disturbance will not form imo. Sandy156 :) 18:37, May 30, 2019 (UTC)

Nothing else is expected to come in the next 5 days...but the EPac is warming up a bit and will probably get a named storm or two around early-mid June. May is only suposed to get a named storm once every two years anyways. Ryan1000 04:08, May 31, 2019 (UTC)

June

Began a short while ago, but nothing is expected to form in the immediate future here. Ryan1000 01:58, June 1, 2019 (UTC)

AOI: SW of Mexico

AOI: SW of Mexico

This one just popped up. 0/20. Beatissima (talk) 00:24, June 20, 2019 (UTC)
