Nora continued to the northwest, and explosively deepened on the 5th and 6th to a 185 mph super typhoon. At the time, it had a minimum central pressure of 875 millibars, the lowest pressure on record at the time and currently tied for 9th. The typhoon weakened as it headed to the northwest, and struck northeastern Luzon on the 7th as a 115 mph typhoon. Nora continued to the northwest, weakening to a minimal typhoon as it hit southeast China on the 10th. The typhoon caused 18 fatalities, with over $2 million in damage.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. This is the same list used for the 1969 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.).
