Part of the 2021 Pacific typhoon season

Tropical Storm Lionrock, known in the Philippines as Tropical Depression Lannie, was a weak and slow-moving tropical cyclone which caused some damage to the Philippines, Vietnam, and South China in early October 2021. Lionrock was the seventeenth named storm of the 2021 Pacific typhoon season. It formed as an area of convection on October 2, then passed through the Philippines two days later. The system emerged to the South China Sea and had further development. On October 7, the system strengthened to Tropical Storm Lionrock, and made landfall in Hainan on the following day. It moved slowly over the island, and later emerged to the Gulf of Tonkin. Lionrock made landfall in Vietnam on October 10 and dissipated later that day.

Lionrock killed eight people along its path: Four in the Philippines, and two in Hong Kong and Vietnam respectively, and damages related to the storm was $74.9 million (2021 USD).
