Tropical Storm Yagi (2018)

Tropical Storm Yagi, known in the Philippines as Tropical Storm Karding, was a moderate but damaging tropical cyclone that was part of the 2018 Pacific typhoon season. The storm origninated on July 31 as a tropical disturbance southwest of Iwo To. The system intensified into a tropical depression on August 6 after several days of being over favorable conditions while moving westward, while PAGASA gave it the local name Karding. Though it was disorganized mainly due to moderate vertical wind shear, excellent outflow allowed the storm to intensify, and by August 8, it strengthened into a tropical storm, receiving the name Yagi (ヤギ, "Goat"), which refers to the constellation of Capricornus in Japanese. Yagi moved erratically before steering northwestward on August 9, as thunderstorms broadened close to the center. As it continued to battle vertical wind shear, the storm deviated and turned west on August 11, before resuming its northwestward path. That day, Yagi attained maximum sustained winds of 75 km/h (45 mph) and a lowest barometric pressure of 990 hPa (29.23 inHg). While north-northeast of Taipei, Taiwan on August 12, the Joint Typhoon Warning Center assessed that Yagi reached maximum 1-minute winds of 100 km/h (65 mph). The storm then made landfall over Wenling, Zhejiang, leading to rapid weakening from land interaction. Yagi recurved eastward on August 14 into the Bohai Sea, where it transitioned into an extratropical cyclone on August 15, and dissipated the next day.

In the Ryukyu Islands, strong winds were recorded and flights were disrupted, and in Miyakojima, the island experienced "once-in-50-years" rainfall. Yagi enhanced the southwest monsoon over the Philippines, pouring heavy rain over several regions of Luzon. The storm damaged 3,379 homes and left Metro Manila littered with trash. Swollen rivers led to impassable roads, and in ports, 193 people were left stranded. The storm killed five people throughout the country, most of which died from drowning, and left eight missing. Overall, damage in the Philippines totaled ₱996.001 million (US$18.913 million). In China, Yagi brought strong gales during landfall, and flooded many rivers and tributaries. Heavy winds and storm surge damaged much of Jinshan City Beach and caused a signboard in East Nanjing Road to kill three people and injure six. Yagi also produced the first ever tornado outbreak in modern Chinese history, causing property and agricultural damage, leading to an economic loss of up to CN¥2.51 billion (US$379.383 million). Elsewhere, the Korea Meteorological Administration expected Yagi to make landfall along the China–North Korea border and bring much needed rain to alleviate a deadly heat wave, though the storm turned away from the area.
