Re: WPAC: GONI - Typhoon
We're definitely going into eyewall replacement right now. Outer eyewall is pretty tight in (which makes sense considering how compact Goni is), so as long as it isn't disrupted by shear, it might run through this one efficiently.

The JTWC anticipates weakening due to shear and a loss of a poleward outflow channel disrupting the EWRC.
Also, in their 18z discussion, they mentioned that they went above satellite estimates due to them likely underestimating Goni based on its compact nature. That bodes well for a further intensity bump at 0z.

Re: WPAC: GONI - Typhoon
Hi guys, we are looking at about what, 36 hours before it hits us here... I'm going to document this with short hour by hour clips, this will be one for the ages.
Its unprecedented, a storm of this magnitude striking a mega-polis...
Kindly keep us in your prayers, regardless of your beliefs.

Do you think a PDS Super Typhoon Warning is possible if Goni refuses to weaken up until landfall?

Yeah its possible a TCWS#5 will be raised... if PAGASA gets it over the 220 km/h hump... I think if JMA gets it to 120kt PAGASA will follow...

Re: WPAC: GONI - Typhoon
I’ve went back and looked at the satellite images and microwave, water vapor, all that. And wow, it is very impressive. This has maintained a T7.5 for 18 hours now, which is really impressive. And EWRC is beginning but I believe this peaked at atleast 160-165kts. Unfortunately we’ll never know. This could be 175knts+ for all we know. Hopefully JTWC can increase the intensity post analysis. This will undoubtedly end up as the strongest storm globally in 2020.

When was the last time they used #5? Mangkhut? Haiyan?

Signal #5 was introduced because of Haiyan I believe. Mangkhut only got up to a signal #4, so I believe probably never (yet). Of course hoping the worst won't come to pass this time around.
EDIT: Nevermind, see post below

Haiyan was the cause of PAGASA now having a #5...
The last time they used was in 2016's Haima (Lawin) over Cagayan and Isabela in Northern Luzon.
Metro Manila was raised to a #4 during STY Angela in 1995.

Oh wow. I haven't really paid much attention to those signals

Re: WPAC: GONI - Typhoon
I know it's going into EWRC, but I'd probably go with 160kts at 0z, which I think JTWC will. We're about to find out
