Looks to me it's slightly intensified last loop.

Of course the storm has got loose power over land no fuel. When yasi hit us it was still a force 4 hundred miles inland and that was tame in compassion to this storm and there was no water on the other side. Its at 127 KNOTS now and moving closer to warm ocean again what constraints do you see holding it back then it still looks great on loop it's not a TD and its not going to take days to build. I note you said before it cannot reach intense status again i respect your opinion . When it does i will re quote back for you page 51.

it will probably peak at 120 KT in the South China Sea and strike Vietnam at 115-120 KT. No chance this regains its former intensity. The oceanic conditions are not that favorable in the South China Sea.
That said, I dont understand JTWCs reasoning of a cat 2 equivalent at landfall. I'm seeing winds on the EC at nearly 120 KT near Vietnam and the GFS also does not indicate weakening.

Re: WPAC: HAIYAN - Typhoon
Hopefully the chasers are safe and there is no signal to communicate to the outside world that is keeping them not to report.

What's the MPI near the Vietnam coast? I know the SST's drop off sharply further west... maybe that's why JTWC is bearish on the intensity.

Haiyan makes Bopha and Megi look like child's play, I'm surprised 2013 was able to poop out something as insane as Haiyan...even for the Wpac. I compared it to all the strongest TC's I've tracked since 2005 and I can't find one that matches but I think Joan from 1997 looked similar to this and some others. I have to agree it appears to be a legendary weather event and likely in the Top 5 strongest TC's in world history. If I were to assign a pressure and wind estimate (at its peak strength), I'd say 175-180 knots with a pressure of 867 mb (similar to CrazyC83). Believe it or not, it could have improved further if the eye got even warmer and the thick ring of -85ºC+ cloud tops expanded even more. I have to say I'm amazed it got to this level even though it was obvious it was going to become a CAT5, the strongest TC this year, and make landfall above 140 knots. My old thinking was 150 knots...off by quite a bit!
I've actually waited many years for this scenario, I wonder what the scenes will be in the area that got the NE quad of this 195 MPH+ buzzsaw. Hopefully some weather instruments survived. Also daytime for the storm chasers that intercepted history. This was the ultimate test for the Philippines that's all I can say.

Re: WPAC: HAIYAN - Typhoon
I don't know how or where people of the Philippines would even evacuate to. What scary radar images of Haiyan. My thoughts and prayers go out to the citizens of Philippines.

Haiyan significantly weakened, but is still much stronger than most of storms which crossed the Philippines.

Re: WPAC: HAIYAN - Typhoon
Passing over Coron now, hopefully the eyewall is just north of the coast.
