I’m extra bullish with my prediction: 150-155 kt and 900-910 mbar. The very deep CDO and tiny eye at this point indicate Goni is going to be something other than a normal Cat 5.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Goni is doing everything he can to be the stronger of the two this time. I think it will be pretty close when both storms are done

Well not yet. Goni seems to be having trouble completely clearing its eye. It’s probably “just” a Category 2 right now.

Yeah obviously not a Cat 5 yet but it could get stronger than 140kts... The real question is how will the JTWC handle it? They struggle with RI sometimes

The eye looks like it’s collapsing. Maybe mid-level shear struck again?

There must be some serious discussion ongoing at JTWC right now... Best track update is over an hour late!

EDIT: As soon as I posted that it updated...
22W GONI 201029 1800 16.3N 133.4E WPAC 120 943

Also it appears the 12z BT was revised to 90kts

Holy ****, all the way up to 120 kt in just six hours! Goni’s 6hr intensification of +40 mph is the highest all year, exceeding Amphan and Haishen (both +30 mph).

They were pretty aggressive as well during Haishen’s RI phase, but then refuses to upgrade it to a Cat 5 despite maintaining a full W ring around a +20C eye for like a full day.
