I would also like to get information directly from the US military 'Joint Typhoon Warning Center" web site at https://www.npmoc.navy.mil/jtwc.html, but alas, they have blocked access from the Philippines - I think because in the past some BAD Hacker (not all hackers are bad according to the most accurate definition) committed his dastardly deed from the PI thereby punishing all its residents. But try it cuz you'll probably be able to bring it up. Also many of the other sites get updated info from JTWC so indirectly as least, the info is available.
And if you like moving pictures and can spare the download time there is one called "Guam IR Loop" http://www.goes.noaa.gov/guam/guamloops/guamir.html. It downloads about 8 infra-red satellite images at 1 hour increments (I don't mean it takes 8 hours to download - though it might if you're still bound to a modem) then replays them in a cyclic order to display the storms motion. It is somewhat limited in its geographic coverage but does cover Guam, The Philippines, Taiwan, Eastern China, and southern Japan. But then why would those of you in Iowa care about typhoons anyway?
Another that presents lots of data is http://weather.unisys.com/hurricane/w_pacific/2007/index.html. The "2007" part is for the year and if you edit that to 2006 you will see a collage of last year's storms here in the western Pacific. Looks like a lot - right?

There are other sites I do check from time-to-time but the above are my favorites at this time.
Well, enough of this. I'll undoubedly come back to typhoons when one threatens, and I'm sure there will be some to tell you about. So stay tuned.....
