Typhoon (Yutu) in WPAC

Chacor · #61 Postby **Chacor** » Sat May 19, 2007 4:26 am

Uh, isn't 80 kt only Cat 1?

#62 Postby **Aslkahuna** » Sat May 19, 2007 4:51 am

The 80 kt from the Tokyo Advisory is a 10 minute wind not a one minute wind. It translates to about 90kt one minute which would make it Cat 2 except that the Category classification is valid only in those WPAC areas covered by NWS Tiyan Guam.

I was actually referring to the JTWC's 80kt, without realising that they had indeed bumped it to 85 kt (Cat 2). :oops:

Well; I guess I was wrong: it looks better now than ever.

#69 Postby **P.K.** » Sat May 19, 2007 5:26 pm

Up to 90kts now.

I always wanted to say that.

Yutu still maintaing 90kts according to JMA.

For those who don't know the story behind the name I found this:

Yutu - The Jade Hare. The hare which lives on the moon. Chang'e, wife of Yi (a tribal chief in ancient China), stole her husband's elixir of immortality, and fled to the moon together with the hare. They are said to be still living there in a palace.

JTWC has actually increased intensity back to 105 kt (it was 105kt at 18Z but 100 kt at 00Z).

Chacor · #74 Postby **Chacor** » Sun May 20, 2007 5:15 am

In fact, it's strengthened further, amazingly: T6.0 from SAB and JTWC and T5.5 from AFWA.

Could be even stronger.

AFWA just joined in with T6.0 - all three agencies giving T6.0/115kt now.

This intensification is quite remarkable given that the JTWC has called for weakening for the past few advisories. It continues to intensify in a relatively positive environment, but cold waters should shortly put an end to this amazing run.

JTWC just went with 125 kt gusting to 150 kt. That was quick. Any more intensification and we'll get a May super typhoon.

That's Sustained 145 mph, strong category 4, gusting to 175 mph
