Severe Tropical Storm Ampil, known in the Philippines as Severe Tropical Storm Inday, was a tropical cyclone that caused moderate damage in the Ryukyu Islands and East and Northeast China in late July 2018. The tenth named storm of the annual typhoon season, Ampil developed into a tropical depression east of Luzon on July 17. The system gradually strengthened over the following days amid a marginally favorable environment and became a severe tropical storm late on July 19 as it moved northwest. Maintaining its strength, Ampil passed over Okinawa Island from July 20 to 21. Thereafter, Ampil weakened slightly while crossing the East China Sea, before making landfall in Shanghai, China, on July 22. The system weakened slowly over land and degraded to a tropical depression on July 23. The system turned eastwards as it continued weakening over land, diminishing to a remnant low on July 25 and dissipating fully a day later over the Russian Far East.

Ampil produced gusty winds across the Ryukyu Islands from July 20 to 21, causing disruptions to transport and businesses. Moisture extending from Ampil also caused thunderstorms in Fukuoka. From July 22 to 25, Ampil generated heavy rains across much of East and Northeast China, affecting more than 2.3 million people and causing record-breaking flooding within the watershed of the Songhua River. About 387,000 people were evacuated from coastal areas in Shanghai, Jiangsu, and Zhejiang. Transport was severely disrupted, with 600 flights into Shanghai canceled and ferries and rail services suspended. A person in Shandong was killed by a fallen tree. About 7,200 houses were damaged or destroyed, while 169,000 hectares (420,000 acres) of cropland were damaged. Direct economic losses reached ¥1.63 billion (US$246 million).^{[nb 1]}
