Looks to me like 50-55 knots.

As usual, the JTWC is being well the JTWC.

We should have a typhoon out of this by afternoon, its organizing fast.

[Cyclenall]

Mujigae has a clear, well defined eye that is very symmetrical with a brilliant spiral band formation on satellite. Its true it doesn't look quite as strong on IR. It looks like its between 65-85 knots right now and JTWC says its 55 knots. What is going on here?

[Yellow Evan]

It's the JWTC, you expect real intensity estimates?

I'd go with 70 knots now.

[NotoSans]

I don't know why JTWC goes with the MET.

It's rapidly intensifying alright...

Latest track has it passing over a very populated major city, Zhanjiang, home to +7 million people...

[Alyono]

its not 65 kt... may be closer to 85 kts

[NotoSans]

JTWC loves to go with MET...even when DT is quite clear cut

[Yellow Evan]

Based on the DT from JTWC, CMISS ADT estimates, the old DT from SAB, that would supports around 80 knts there. However, I'd go with 85 knots now.

[NotoSans]

This is getting ridiculous. I just did a six-hour average for DT and obtained a value of 5.17. Three-hour average is definitely at 5.5. I don't know why JTWC keeps on going with the MET.
