The binary interaction with 97E and 98E will be fascinating, because even though 97E is expected to be the weaker of the two systems (just based on slightly lower SSTs and OHC) it also looks to have a larger envelope. Thus while 98E might be stronger intensity wise, they could have equal pull on each others circulations. To make matter even more complicated it also appears there is a budding disturbance to the east of 98E that also has a shot at development in the medium range. Overall lots of players on the table... One of the more impressive ITCZ breakdowns I've seen in recent memory.

Interesting end to the epac season. Can't get much in the heart of the season then October explodes (or is about to). Very El Nino-ish, despite the ocean being anything but. Hmm-- maybe a 1957 type of scenario where you get one storm near Mexico then another one coming in from the wsw in October.

Oh, hey! How are you?

DO you think one of these-- perhaps 98E-- might become a landfalling 'cane?

P.S. While it's late-season for the EPAC, October is actually the climatological peak for major landfalling 'canes on MX's W coast-- so this burst of potential coastal threats right now feels about on schedule to me.

Invest 98E is now TD 10E. The track forecast is awesome-- but the intensity forecast peaks at a rather blah 55 kt. They seems to be following the SHIPs, which shows increasing shear as it approaches the coast. The other models are more aggro, including the HWRF, which is pure porn-- showing it at 120 kt by Day 5 and still strengthening as it approaches the coast:

Lost o' news at 2 am PDT:

* TD 10E should become a TS today. The Discussion notes that most of the intensity guidance has bumped up a bit, and the new forecast makes it a hurricane as it approaches the MX coast later in the forecast period.

* 98E is upgraded to TD 11E. The forecast has it making a big wide recurve-- turning N near 120W and then accelerating ENE in the general direction of the MX coast as a moderate TS. Avila's bone-dry Discussion hints at this system possibly combining with TD 10E, as per the GFS, although that would seem a bit strange.

Lots to watch over the next couple of days. Lord knows how this will all evolve. It's an odd map, with these two cyclone so near each other, and taking such similar paths.

10E will probably be the dominant cyclone, but I hope it starts recurving faster soon to avoid weird interactions with 11E. It looks like the better scenario for a strong LF is S of PVR and a RIC as it accelerates NE... I would prefer it to also keep a distance from the base of the trough.

I swear to god you get the forecast I send out to clients every morning :D

Yeah, it looks the other way to me also, many times. I'm about to write something, and I just have to reply to your comment and say "yeah, I agree". Good, I can go down in flames with company now :P

Oh. There you are.

Irwin is indeed a storm, and 10E now forecast to hit Mexico as a hurricane.

Yep-- I mentioned this in the 2 am PDT update (above).

Get a room.

Maybe the HWRF is like nude anime chicks. Not quite real enough to believe? :)

:lol:

Yep.
