Encyclopedia
Super Typhoon Flo was the strongest and costliest storm of the 1990 Pacific typhoon season
. A powerful super typhoon, it had managed to cause $4 billion in damage. It developed on September 8, rapidly intensified on the 16th and 17th to a 165 mph super typhoon near Okinawa. Vertical shear weakened it as it recurved to the northeast, and Flo hit Honshū
, Japan on the 19th as a 100 mph category 2
typhoon. It continued rapidly northeastward, became extratropical
on the 20th, and the extratropical cyclone dissipated on the 22nd. Widespread flooding and landslides killed 32 and caused billions in damage.
Typhoon Flo was the costliest typhoon in the West Pacific at the time. Now it ranks as the 8th costliest Western Pacific typhoon of all time, only to be surpassed by Typhoons Mireille

Vertical shear weakened it as it recurved to the northeast. However, it entered cooler waters and an area of wind shear, causing it to weaken slightly before landfall, and Flo hit Honshū, Japan on the 19th as a 100 mph category 2 typhoon, causing floods and landslides that killed 32 people. It continued rapidly northeastward, weakening and dissipating rapidly, and racing northward. Super Typhoon Flo became a tropical depression, and became a remnant low on the 20. The remnants of a former Typhoon Flo continued northwards, and would dissipate by September 22.
In Okinawa, it managed torrential rainfalls that resulted in deadly floods and landslides. It killed several people and caused billions of dollars in damage.
Overall, damage was totaled 4-6 billion dollars across Japan.

Meteorological History
A tropical depression developed on September 8 and rapidly intensified into a tropical storm the next da. The system intensified explosively on the 16th and 17th to a 165 mph super typhoon near Okinawa, reaching a low pressure of 891, making it one of the most powerful storms ever recorded.Vertical shear weakened it as it recurved to the northeast. However, it entered cooler waters and an area of wind shear, causing it to weaken slightly before landfall, and Flo hit Honshū, Japan on the 19th as a 100 mph category 2 typhoon, causing floods and landslides that killed 32 people. It continued rapidly northeastward, weakening and dissipating rapidly, and racing northward. Super Typhoon Flo became a tropical depression, and became a remnant low on the 20. The remnants of a former Typhoon Flo continued northwards, and would dissipate by September 22.
