Part of the 2018 Pacific typhoon season

Typhoon Maria, known in the Philippines as Super Typhoon Gardo, was a powerful tropical cyclone that affected Guam, the Ryukyu Islands, Taiwan, and East China in early July 2018. Developing into the eighth named tropical storm of the 2018 Pacific typhoon season and passing the Mariana Islands on July 4, Maria strengthened into the fourth typhoon of the season and underwent rapid intensification the next day amid favorable environmental conditions. The typhoon reached its first peak intensity on July 6; subsequently, Maria weakened due to an eyewall replacement cycle, but it reintensified and reached a second, stronger peak intensity on July 9 with 10-minute sustained winds of 195 km/h (121 mph) and a minimum pressure of 915 hPa (mbar; 27.02 inHg). Over the next three days, it started to gradually weaken due to another eyewall replacement cycle and decreasing sea surface temperatures. After crossing the Yaeyama Islands and passing north of Taiwan on July 10, Maria ultimately made landfall over Fujian, China, early on July 11, before dissipating the next day.

Early in its lifetime, Maria brought winds of tropical storm force to Guam, damaging aircraft at Anderson Air Force Base and knocking out power across the island. Damage in Guam was valued at US$150,000.[nb 1] On July 10, Maria brought strong winds to Okinawa Prefecture, inflicting significant crop damage. Losses in the prefecture reached JP¥853.7 million (US$7.730 million).[nb 2] Simultaneously, Maria produced heavy rains and strong winds across Taiwan, killing one and injuring eight. Power to nearly 60,000 households was cut and agricultural damage was around NT$1.3 million (US$43,000). From landfall to dissipation, Maria impacted the Chinese provinces of Fujian, Zhejiang, Jiangxi, and Hunan with flooding rain and gusty winds. At least 510,000 people in coastal regions evacuated and one person was killed in Jiangxi. Around 9,300 houses and over 37,000 hectares (91,000 acres) of cropland were damaged. Schools and workplaces were closed in parts of Fujian and more than 200 flights were cancelled. Train and ferry services were also disrupted. Power outages were widespread in Fujian, where more than 320,000 customers lost power. Economic losses across China were about CN¥4.16 billion (US$629 million).
