#Gaemi now has few 170+ kt bins at NW quadrant on Ishigaki radar. 4-bin average is ~165 kt, which results in 140-145 kt surface wind. Reflectivity x-section (h/t @weather_models ) shows obvious stadium effect, which is a sign of intense TCs.

Bedout island enters Cyclone #Ilsa 's eye. The minimum pressure so far is 931.7 mb. The max sustained wind is 113 kt and max gust is 150 kt. Given that the eyewall sampled is not the strongest and Ilsa is slightly after peak, this could support a Cat 5 intensity at the peak.

#Gaemi continues to intensify according to radar despite lackluster IR appearance. JMA didn't dealias correctly so I processed the data again. The corrected velocity shows some 160kt pixels at E quadrant at 2300 m, which yields ~140kt surface wind.

This is just perfect. Because of the higher tropopause temperature as mentioned before, the true intensity of #Hinnamnor is likely higher than Dvorak estimates, which somehow reminds of Dorian.

Did a quick regression of pressure series recorded by this buoy using radar-derived RMW and got ~899 hPa central pressure. This curve also (surprisingly) has good agreement with the pressure obs from Yonagunijima.

At 00Z today, drifting buoy "5201802" recorded an MSLP of 949 mb at a distance of ~28km west of Typhoon #Gaemi 's eye. This supports a central pressure of ≤920 mb based on Schloemer equation. Good support for supertyphoon intensity especially when combined with radar velocities!
