West Pacific Tropical Action 2012


Recommended Posts

eye on JMA radar...

6hta8y.png

sustained winds of 20 to 30kt and gusts of up to 40kt starting to be recorded in Okinawa... ROAH (Naha) reporting pressure at 991mb and decreasing... Kadena AB is now at TCCOR 1 btw... :popcorn:

btw, looks like the eyewall has improved after that EWRC... if it had more time, it would probably be stronger than what it is now...

Talim is a somewhat interesting tropical cyclone, looks like it's gonna impact a broad part of coastal Asia including China, Taiwan, and Japan. Shear is inhibiting it for now, and it looks like SSTs and topography are gonna be a problem soon, so probably no typhoon. Full analysis and forecast on my blog: http://weather.schematical.com/

Guchol made landfall near Nanki-Shirahama in Kansai prefecture not so long ago. Widespread tropical storm force wind gusts are occurring near and to the east of the center (including metropolitan Tokyo), with hurricane force wind gusts occurring at Shizuoka (despite Guchol only being a tropical storm now). The worst is yet to come for Tokyo. Full analysis on my blog. http://weather.schematical.com/

^^^ izu islands reported sustained winds of around 62mph and gusts of up to 85mph last night... Shionomisaki, otoh, bottomed out at 966hPa as Guchol made landfall... even Tokyo wasn't spared from the winds and rains, here's a footage from a friend who lives there... but whatever, it was a normal day for them lol

Doksuri has grown quite a bit in size overnight

Yup, Doksuri is putting up a very nice central dense overcast, but it is misplaced from the center due to 20-30 kt of wind shear. JTWC expects that Doksuri won't intensify much more, and I have to agree considering how misplaced the circulation seems to be from the center of the convection. Also only a day until landfall. I put a full analysis of Doksuri on http://weather.schematical.com/

  • 3 weeks later...

we got TS Khanun now moving just north of Okinawa.. Daito Islands reported 40mph gusts earlier and a minimum pressure of 995hpa... Amami Island also beginning to report sustained 30mph and gusts of around 40mph as well... it's a weak storm and TCCOR remains at 4 for Okinawa...

Yup, this is a rain event for the southern islands and then Korea tomorrow. The bigger story will be a system that forms late this week/over the weekend in the Philippine Sea. That system has a much better chance to become a typhoon.

I like the Sunny Side Up optimism there. May be too close to land for really spectacular satellite imagery, however.

Not sure if directly related to Vicente. but rainfall around Metro-Manila was sufficient yesterday that Santo Tomas cancelled classes for Monday (Sunday afternoon US time)

ETA:

A clear eye was briefly visible on the visible loop, it probably is typhoon strength.

The WPAC is nice and all with the quality of storms, but the way the different agencies handle each system is a bit frustrating sometimes.

Vincente appears to be a more dangerous system than previously thought. Could wander to Hong Kong...

Looks like it's heading more for Macao than Hong Kong.
