Interesting that the JMA is not forecasting typhoon strength, given Kajiki's current appearance.

Not sure where you got that from, but the 2100z update peaks it at 65kts, as the 21z (an intermediate update) is no different than th 18z forecast. Forecasts typically change only on the 00/06/12/18z updates.

RJTD up to T5.0 so this will certainly be a typhoon in the update in 30 min or so.

These typhoons tend to often get stronger than forecast for some reason...

Increase of 3.0 in 24 hours? Unreal!

Kajiki has a very impressive structure at the moment:

I wouldn't be surprised if it were indeed much stronger, as that SAB bulletin would seem to indicate.
