Re: WPAC HAGUPIT (PAGASA: Nina): Tropical Storm - Discussion
This system already has the looks of a major typhoon.

Actually, not really. Quite a number of storms these days in the WPac have a majority of convection in the S quad and only a weak eyewall in the N quad. That's not a major typhoon.

Right, fair enough, but it also depends what you mean by major:

STS Bilis in 2006 never reached typhoon strength, peaked at 60 kt and killed over 600 people.

Re: WPAC HAGUPIT (PAGASA: Nina): Severe Trop Storm - Discussion
There's been an uncommon amount of shear in WPAC recently which is why the storms have not been able to get strong convection all of the way around and keep it there. In this case, however, it looks as though Hagupit has dry air issues. Probably in the mid levels as Trade Air which usually has strong subsidence above H7 in WPAC can entrain into storms from time to time. Ironically, PAGASA calls this storm Nina (my first wife's name) but Hagupit is also one of the International names submitted by the Philippines.

It looks like an 85 mph category 1 in that loop, with very deep
white convection around the center. This could really intensify rapidly.
Yes,and CDO is better than before.

Re: WPAC HAGUPIT (PAGASA: Nina): Severe Trop Storm - Discussion
Hagupit looks like it's going to thread the gap between Taiwan and Luzon. I finished the typhoon shoot in Taiwan yesterday and am now in Hong Kong due to fly out on Wednesday....as you can probably guess I'm going to delay my flight.

Pressure down again at 06z but still no change in winds.
