Yup most likely tomorrow afternoon, will post updates here. And then Bolaven after that, wherever that beast ends up!

Re: WPAC: TEMBIN - Typhoon
so only a 75 knots category 1? i think not...this is way way stronger...my personal intensity is 110 knots category 3 as the eye isn't fully circular...

Maybe you have to stay in Taiwan for a week, for two typhoons.

Uploaded with ImageShack.us
that is from Wunderground.. and no since the winds are shown in Kts so that would be around 70kts--not a STY??:) this data is easily accessible and contains both ECMWF and GFS data... i'm quite surprised the ECMWF continues to be available in their site since most euro products are usually not allowed to be reproduced or something...
anyway i am surprised that PAGASA is keeping this at 105kph TS?!?!
as for the strength, the only thing that i'm "worried" about is if the eyewall continues to contract and chokes... right now, the eye diameter is around 10 nm..

THE CURRENT INTENSITY IS BASED ON DVORAK ESTIMATES OF 65

why don't they use estimates from cimss which is in real-time? already near 100 knots or more...

First landfall will be in eastern Taiwan, probably as a category 4 system
Second landfall could be somewhere in eastern Guangdong Province (east of Hong Kong) possibly Shantou
But, it is far too early to be guessing what the impact on China will be

PAGASA still has it at 105 kph...but they might upgrade this to typhoon in their next advisory

Here are links to the Japanese Meteorological Agency forecast track: http://www.jma.go.jp/en/typh/1214.html
Tropical Storm Risk, which uses Joint Typhoon Warning Centre data (you can't access JTWC in HK without a proxy): http://tropicalstormrisk.com/
And finally HK Observatory forecast: http://www.weather.gov.hk/wxinfo/currwx/tc_gis_e.htm
You can consult these very useful links to get a good idea yourself where the storm is forecast to hit by three of the regions' top forecast centres.

Re: WPAC: TEMBIN - Typhoon
Looks to be strengthening even further now, raw Dvorak at T6.4 and colour satellite imagery shows one heck of a powerful storm. Already a solid cat. 4 in my opinion! I expect JTWC to have this at 115-120kts in the next update out in about 1 hour.
