what do you think about the second system for next week... looks more interesting to me...:unsure:

Well, the GFS is taking a typhoon into Tokyo, so yeah, more interesting.

I've got genesis timed for May 12 and a WNW track to start (not exactly a big leap). Beyond that, I'm not sure.

You're not really kidding. Of course, oceanic heat content may be an issue in May.

and now the EURO is picking up on it as well.. not that strong compared to GFS but it's there...

Yeah, that's a good point, Steve. I'd imagine the topography of Luzon enhances that effect.

Most definitely, but the Visayas (Central Islands) aren't exactly flat either. Early May through early June is the hottest time of the year in Central Luzon being the time of the intense heating prior to the onset of the monsoon. Temperatures actually exceed 38C (100F) in places during that period. The thunderstorms that occur can rival the most intense the US has to offer with damaging winds, large damaging surface hail, and, yes, even tornadoes.

Looks like the circulation has become a bit better defined on microwave... although most of the convection is on the west side of the circulation.

Sorry, Phil, just saw this now. That MW is waaaay better than it was at 8z Friday. Convection is still meh, but it's obviously slowly intensifying. It's still only going to be a 50 kt TS at best, but at least it is getting better organized.

Aere was looking pretty impressive for a time during the diurnal max, but then convection temporarily collapsed due to some land interaction. We have some convection redeveloping now, but It likely will be too late to give it any hope of attaining hurricane status before it heads into Luzon.

Aere has made landfall in the Philippines and will begin recurving today. The track will go east of Taiwan.

Invest 94W is looking better this morning and could develop later in the week. Interestingly, the GFS remains the only deterministic model showing development. About 20-30% of the Euro ENS members are showing development. The track forecast is all over the place still, from the South China Sea to recurving east of Japan. The Euro ENS likes a track similar to Aere.

hello! i have a question.... on Sunday, just before Aere made landfall, many were forecasting it to move NW-ward inland... obviously it didn't and instead moved north, parallel to the coast... is it because of topography or the STR?? thanks

anyway as for Invest 94W, the ECMWF (12z) is showing it as well now... JTWC giving it a "poor" forecast currently...

I haven't done an in-depth analysis of the synoptics, but my guess is that that models were slightly too strong with Aere, which would have lead to more latent heat release and would have slowed the s/w trough moving through China (which is what is ultimately causing recurvature). The convection has really fallen apart over the last 24-36 hours, which wasn't modeled particularly well.

  • 2 weeks later...

You're right about the blah globe. What piques my interest is that usually we start to see evidence of the Summer monsoon developing SW of India but as of yesterday there was little or nothing in the way of activity there.
