[RL3AO]

Wow a major hurricane already? This wasn't expected.

Cat 4. Could be a cat 5 in a few hours. Its been bombing the last 6-10 hours.

JTWC maintains the CPHC initial intensity, correct? While JMA analyzes differently, even though they are official?

Yes JTWC will maintain the intensity. And yes JMA will analyze this differently since they use the 10 min wind scale which is low and a totally different scale that needs to be revamped.

JTWC, NHC and CPHC uses 1 min.

CATEGORY 4? WHAT AN AUGUST! TOTALLY UNBELIEVABLE!

[euro6208]

Absolutely beautiful yet intense hurricane. We have now 3 different major hurricane/typhoon occurring in all north pacific basins within the last few days.

Holy crud what the heck is going on with the Pacific Ocean??? She decided to get her stuff together in a hurry.

[SeGaBob]

It's amazing how a storm can struggle all the way across the Pacific then suddenly RI... Persistence paid off for this system.

Remember when people were saying this was a bust?

The eye is at 179.5 and should enter the Wpac later today. Genevieve wants to make a grand entrance to our area.

Wow what a jump in intensity. I don't think I've ever seen a 50 mph jump between advisories. 960 mb is pretty high for pressure though.

Wow what a jump in intensity. I don't think I've ever seen a 50 mph jump between advisories. 960 mb is pretty high for pressure though.

The environmental MSLP in the international date line region is also pretty high. 960mb seems to be a reasonable estimate

[RL3AO]

Eye is still warming. Raw 7.0 from ADT.

[Macrocane]

Wow, I don't check the forum or the CPHC for 12 hours and I miss all the excitement, I didn't check because I wasn't expecting this
Genevieve is the strongest system in the Central Pacific since 2007 Flossie isn't it?

For the record, this thread will be renamed Typhoon Genevieveand moved into the WPac forum when JMA issues their first advisory.

I've been meaning to ask why we separate the WPAC storms into a separate Active Storms forum. Why not have the threads on this page too?

If only the Atlantic could get it's act together for once.

JTWC, NHC and CPHC uses 1 min.

For what it's worth and it's absolutely not a scientifically sound rule of thumb, whatever value JMA assigns to the typhoon's "gusts" is usually within 5 or 10 knots of the value JTWC assigns to the typhoon's 1-minute winds.

This is an amazing storm and I'm just saving images.

I think it has to do with the West Pacific Weather site. Could a mod confirm?

The eye continues to warm (-2.6C) while mean central convection continues to cool (-75.6C). I'd estimate Genevieve around 125kt.

If the eye warms quite a bit, we could have a Cat 5.
