Super Typhoon Chaba was an intense Category 5 super typhoon that struck Japan as a minimal typhoon causing heavy damages
[edit] Storm history
Super Typhoon Chaba formed east of Kwajalein on 17 August and tracked westward under the influence of the low-mid level ridge located north and east of the area. The depression intensified steadily and the first warning was issued by 18:00 UTC on 18 August. The system intensified at a climatological rate and continued to track westward along the southern periphery of the ridge through 21 August. Dual outflow channels developed after 21 August and allowed the cyclone to intensify rapidly and reach a maximum intensity of 185 mph (285 km/h) and a pressure of 879 mbar (hPa) approximately 75 nautical miles northwest of Guam.
A passing longwave trough caused a shift of the track to the northwest and provided for continuation of enhanced outflow which allowed Chaba to maintain super typhoon strength through 06:00 UTC on 26 August. The longwave trough then propagated eastward and caused the mid-level steering ridge to strengthen and shift the track of Typhoon Chaba slowly westward for a couple of days. Another longwave trough subsequently moved off the east coast of China causing the track to shift poleward towards Kyushu on 29 August Typhoon Chaba made landfall near city of Kushikino on the southwest coast of Kyushu at approximately 00:00 UTC on 30 August when Aburatsu station, on the coast, measured winds at 108 knots. Chaba began to accelerate northeastward across Kyushu and onto Honshu near Hikari.
Chaba crossed southwestern Honshu and entered the Sea of Japan where it began to transition into an extra-tropical low. Chaba weakened to a tropical storm, skimmed the northern edge of Honshu before crossing into Hokkaido near Shizunai and the system became an extra-tropical low around 06:00 UTC on 31 August.
