On November 14, 1970, a tropical disturbance organized sufficiently to be designated a tropical depression. A steady intensification carried Tropical Storm Patsy's windspeeds up to 155 mph (250 km/h) and a minimum pressure of 918 mbar. It made landfall in Luzon with sustained winds of 130 mph (210 km/h) on November 19. After emerging in the South China Sea, Patsy remained at tropical storm strength. It struck Vietnam during its Civil War as a weak tropical storm on November 22. The 8-day-old cyclone dissipated shortly after its final landfall.
