BTW... here's a link to official tropical cyclone information.

http://severe.worldweather.wmo.int/

Remember... wind speeds are in 10-min averages, so multiple them by 1.14 to get a 1-min wind like the US uses.

Those are the same pictures you posted a few hours ago. There hasn't been a DMSP pass for several hours.

If you check out NRL, there are some 2330Z images from a different polar orbiting satellite -- a lot better than 17Z images.

Realistically, Chanchu is probably near or just made category four now.

Looking very impressive.

I think chanchu is done strengthening for now...

Yes, CHRISTY, it looks like the front is really taking it's toll on Chanchu now.

No change, officially... still around 103KT.

Still a very dangerous storm right now even though Chanchu has begun weakening.

I see that Hong Kong is in the path. I understand the windspeed thing, but this thing looks like a SS Cat 4 at best....135kt *1.14=154kt...*1.15=177mph.....no way. I've been wondering if they do something different to measure intestity over there.
