Super Typhoon Wipha

An area of disturbed weather formed southeast of Naha, Okinawa early on September 13. This area gradually became better organised, and a TCFA was issued late on September 14. The JMA upgraded the storm to a tropical depression on September 15, and the JTWC soon followed suit with Tropical Depression 13W.

PAGASA named the storm "Goring" later that day. On September 16, the storm had gained enough organisation to be designated as a tropical storm. On September 17, the storm underwent rapid intensification and quickly strengthened into a typhoon. It continued to strengthen rapidly and was upgraded by the JTWC to a super typhoon early on September 18.

In the early hours, local time, of September 19, Wipha slammed into Fuding, near the Fujian-Zhejiang provincial border in China. However, before the storm made landfall it weakened slightly, becoming a Category 3 equivalent typhoon.

The storm toppled hundreds of homes and knocked out power and water supplies as it swept ashore. About 2.7 million people were evacuated in eastern China, including the financial hub Shanghai ahead of its landfall. Wipha landed just where Super Typhoon Saomai, the strongest China had seen in 50 years, hit last year, killing hundreds in Fujian and Zhejiang provinces.
