Severe Tropical Storm Usagi, known in the Philippines as Tropical Depression Samuel, was a tropical storm that made landfall on Southern Vietnam in late November 2018, causing severe damage around Ho Chi Minh City. The storm formed from a disturbance in the Central Pacific basin on November 3, but did not develop into a tropical storm until almost three weeks later, on November 21, after making landfall on Biliran, Philippines. While never considered as a typhoon by the JMA, Usagi underwent rapid intensification and peaked as a Category 2 typhoon on the Saffir-Simpson scale before making its final landfall on Vũng Tàu, Bà Rịa-Vũng Tàu Province as a weakening tropical storm on November 25. Usagi caused one death and ₱52.2 million (US$994,000) in damages in the Philippines, most of which came from agriculture. Usagi caused 3 deaths and ₫925 billion (US$39.5 million) in damages in Vietnam.

Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionOn November 3, the Central Pacific Hurricane Center began monitoring a disturbance that had formed in the Central Pacific basin.[1] This disturbance soon moved out of the basin and into the West Pacific without further development on November 6.[2] Tracking westward, the system did not organize until late on November 18, when it reached tropical depression status on the Saffir-Simpson scale. The PAGASA named the system Tropical Depression "Samuel" and issued warnings for Mindanao and Visayas. Samuel made landfall on November 20 in the Philippines, crossing the archipelago and weakening slightly. Samuel began to restrengthen over the South China Sea, and was subsequently named "Usagi" by the JMA. Usagi underwent rapid intensification, and became a severe tropical storm on November 21 while moving slowly. By November 22, Usagi intensified into a Category 1 typhoon. On November 24, Usagi weakened back to a severe tropical storm as it was moving towards Vietnam due to land interaction. The next day, Usagi made landfall and dissipated afterwards.
