Typhoon Amy, known in the Philippines as Typhoon Gening, was the second typhoon to strike China in a week during mid-July 1991. An area of convection was first observed on July 13 within the vicinity of Yap. A tropical depression developed the next day. While initially tracking westward, the system slowly deepened, becoming Tropical Storm Amy on July 16. After briefly turning northwestward, Amy intensified into a typhoon on July 17. Continuing to intensify as it tracked through the Luzon Strait, Amy reached its peak intensity of 175 km/h (110 mph) on July 18.[nb 1] That evening, the typhoon began to show signs of weakening, although it was still believed to have been a typhoon when it made landfall in the province of Guangdong on July 19, becoming the strongest tropical cyclone to hit the province in 22 years. Once inland, the storm rapidly weakened, and by late on July 20, had dissipated completely.
The storm's large size resulted in flooding, and high winds blew ash from erupting Mount Pinatubo across the Philippines. Around 7,000 people were forced to evacuate from their homes due to the threat of mudflows and approximately 500 homes were destroyed. One person in the country was killed. Thirty-three people were killed and two others went missing after two ships capsized offshore. In Taiwan, three fatalities were reported and roughly 460,000 customers lost power. In the Guandong province, 99 people were killed and 5,239 others were hurt. Roughly 400,000 homes were damaged or destroyed and more than 200,000 ha (494,210 acres) of farmland was flooded. Monetary damage in the province was estimated at ¥23.6 billion (US$4.42 billion). Across southern Fujian, at least 30 people were injured and 1,300 homes were demolished. Damage in Zhangzhou, the region of Fujian worst affected by Amy, was estimated at ¥2.4 billion (US$450 million).[nb 2] Throughout its six-day path, the typhoon was responsible for 136 lives and US$4.87 billion in damage.
