Severe Tropical Storm Prapiroon, known in the Philippines as Tropical Depression Butchoy was a compact tropical cyclone that made landfall in Hainan and Vietnam in July 2024. The fourth named storm of the annual typhoon season. Prapiroon was first identified as an area of persistent convection southeast of Manila, Philippines. It then drifted northward over the South China Sea, strengthening into a severe tropical storm on July 22. The storm's eye became visible on microwave satellite imagery before making landfall in Wanning, Hainan. It soon reached its peak intensity that day, with 10-minute sustained winds of 110 km/h (70 mph) and a minimum barometric pressure of 980 hPa (28.94 inHg). Land interaction prevented further intensification, and it crossed into Quảng Ninh, Vietnam becoming the first tropical cyclone to hit mainland Vietnam in 640 days before weakening on July 24.
Together with Typhoon Gaemi, Prapiroon and its precursor affected the southwest monsoon over the Philippines, leading to significant rainfall across parts of the archipelago as Prapiroon began to move away. In China, twelve counties and cities on the island received rainfall over 100 mm (3.9 in). The remnants of Prapiroon also caused heavy monsoonal rains in parts of Thailand and Cambodia. Overall, the tropical storm was responsible for 23 deaths, 9 missing, and US$18.9 million in damage.
