Its inflow became disrupted by the Philippines to its west, and Patsy hit Luzon on November 19 with winds of 130 mph (210 km/h), making it the 3rd strong typhoon to strike the island since September and made a direct hit over the National Capital Region of Metro Manila, then known as the Greater Manila area, catching many offguard. After crossing the Philippines and weakening to a Category 2, Patsy traversed the South China Sea, where cooler waters kept the system from strengthening. This caused the cyclone to continue a weakening trend until it was downgraded to a tropical storm on November 20. On November 22, Patsy struck Vietnam as a 45 mph (70 km/h) tropical storm, and dissipated soon after.
