WPAC: HINNAMNOR - Post-Tropical

[aspen]

Still a gorgeous buzzsaw despite the EWRC and interaction with 13W. This could make a run for 150-155 kt once the eye fully clears out.

[Hurricane2022]

I'm confident that Hinnamnor is almost a C5 (135 kt)
I would love to see an recon flying into this

Just need the eye requirement and yeah it'll probably have a new peak.

[InfernoFlameCat]

Its devouring the depression. Wow.

Okinawa may have avoided the first peak but once it track northwards, this storm is more bigger. The channel between South Korea and Japan is in the guns.

Storm is looking good. It’s having a little trouble getting rid of the remnant eyewall. It still cannot clear out the eye fully.

I think that might be due to TD 13W blocking some of Hinnamnor’s outflow.

Looks like they revised it

12W HINNAMNOR 220901 0000 22.6N 125.8E WPAC 140 915

[ElectricStorm]

Looks like some shear from 13W might be getting to it now, CDO getting squished a bit on the SE side.

I actually think the JTWC's initial 0z estimate of 135kts is probably more accurate than the revised 140. The eye has struggled to fully clear and has remained pretty ragged. ADT did reach 7.0 earlier so maybe it briefly reached Cat 5 again but it certainly looks to be a bit weaker than that now. Still a beast of a storm though and it might have a chance for a third Cat 5 peak after it fully absorbs 13W.

[ManilaTC]

The LLCC of 13W has completely made the rounds to the NE of Hinnamnor, and was exposed briefly this morning. Its no longer visible in Radar images... I say 13W has been gobbled up.

[doomhaMwx]

As evident on latest satellite frames, the anticipated deceleration/stall of Hinnanmor over the northern Philippine Sea has begun. In addition to increasing shear that's already negatively affecting it, Hinnanmor will be a victim of its own upwelling over the next couple of days.

Super typhoon Hinnamnor expected to land Busan on Tuesday

Super typhoon Hinnamnor, the 11th cyclone for the year, is expected to land on Korea’s Busan and the southern coastal areas in South Gyeongsang Province on Tuesday, changing its course from what has originally been anticipated.

By the time Hinnamnor lands on the Korean Peninsula between Monday evening and Tuesday morning, its central pressure is expected to reach between 940 and 950hPa. Typhoon Sarah in 1995 and Typhoon Maemi in 2003, both of which devastated the country, recorded central pressures of 951.5hPa and 954hPa, respectively.

 Two worst to hit Busan:

 1) 1959 Sarah:

2) 2003 Maemi:

Broad/loose structure. Anyway, radar velocity generally supports the JTWC estimate of 85kts at 09Z.




The eye is forecast to pass over the tiny island of Tarama (between Miyako and Ishigaki) later. Pressure recorded by a station there has dropped to ~968mb (but presumably not adjusted to sea-level).
