Typhoon Wipha, known in the Philippines as Typhoon Tino, was a large typhoon that caused extensive damage in Japan in mid-October 2013. The system originated from a tropical depression well to the east of Guam on October 8. Tracking generally westward, development of the depression was initially slow; however, on October 11, favorable atmospheric conditions allowed for rapid intensification. The depression strengthened to a tropical storm that day, receiving the name Wipha at the time, and reached typhoon status on October 12. Now moving northwestward, Wipha grew into a very large system and ultimately attained its peak intensity on October 14 with winds of 165 km/h (105 mph) and an atmospheric pressure of 930 mbar (hPa; 27.46 inHg). Accelerating and turning more northerly, the typhoon weakened as conditions became less conducive for tropical cyclones. Wipha dramatically accelerated northeastward on October 15 as it interacted with a stalled out front over Japan. Simultaneously, the storm began transitioning into an extratropical cyclone, a process which it completed early on October 16. It is said that the storm caused over 100 million dollars of damage.
Early on October 8, 2013, the United States Joint Typhoon Warning Center (JTWC) reported that a tropical disturbance had developed within an area of low to moderate vertical wind shear, about 670 km (415 mi) to the east-southeast of Anderson Air Force Base on the island of Guam. During that day, atmospheric convection started to wrap around into a consolidating low level circulation center, before the Japan Meteorological Agency (JMA) started to monitor the system as a tropical depression early the next day.
