Tropical Storm Kompasu

Severe Tropical Storm Kompasu, known in the Philippines as Severe Tropical Storm Maring was a very large and deadly tropical cyclone that affected the Philippines, Taiwan, and southeast China in early October 2021. Part of the 2021 Pacific typhoon season, Kompasu originated from an area of low pressure east of the Philippines on 6 October 2021. The Japan Meteorological Agency (JMA) classified it as a tropical depression that day. A day later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) classified it as a tropical depression, naming it Maring. The cyclone was initially heavily disorganised, competing with another vortex, Tropical Depression Nando. Eventually, Maring became dominant, and the JMA reclassified it as a tropical storm, naming it Kompasu. Kompasu made landfall in Cagayan, Philippines, on 11 October 2021, and two days later, the storm made landfall in Hainan, China. The cyclone dissipated on 14 October 2021 while located over Vietnam.

The storm impacted many areas previously affected by Tropical Storm Lionrock a few days prior. Kompasu killed 46 people and 21 others were missing, majority of them were in the Philippines. The country also reported a damage of ₱8.3 billion (US$163 million). Total damage caused by the storm was US$545 million.
