WPAC - Tropical Storm Bebinca

[TheEuropean]

On JTWC site it's TD 19W:



This may become the next Typhoon.

[HURAKAN]

[WindRunner]

The JTWC are strengthening this very rapidly - to a typhoon in 36h and at 85kts in 72h, during which it turns to a due north heading. That'll put it in prime waters for more intensification as it heads up towards/near Japan. Nothing more than a TD without advisories from JMA.

Well... the NRL site's not updating and the FNMOC site is down. Floaters aren't going to be moved, of course.

Also, the NOGAPS model hasn't been working either. What's going on??

One huge complicating factor for intensity is the area of storms to the east. Many models have developed 19W w/ the exception of the useless CMC, but they disagree on the evolution of the second system to the east. Some indiate a binary/fujiwhara interaction where both aren't going to develop much, some indicate this will become the dominant system. Just some food for thought.

EDIT: just looked at the 12Z models and nearly all the models develop both systems quite robustly. ECMWF paints a very queer situation as 19W doesn't get picked up and instead is trapped in a COL area between two areas of high pressure.

[wxmann_91]

New forecast isn't as bullish as the JTWC forecasters have just realized that the UL anticyclone over Guam is going to shear this system quite vigorously through the first 36-48 hours. However I believe that if there is little negative storm interaction after that this could develop quite robustly.

Bebinca is here!!!

PAGASA differs a lot from the JMA and JTWC tracks over this one, PAGASA has it heading west.

This is up to 40kts now, which means that the JMA is higher than the JTWC for both systems in the WPAC right now. JMA's two 40kt TS's beats JTWC's 35kt TS and 15kt TCFA . . . for once.

Holding steady, though the forecast track is further to the south and slower now.
