Super Typhoon Nora (international designation: 7316, JTWC designation: 17W, PAGASA name: Luming) was (at the time) tied with Super Typhoon Ida of 1958 to be the strongest tropical cyclone worldwide, with a barometric pressure reaching 877 mbar (hPa; 25.9 inHg). Nora was the second super typhoon of the 1973 Pacific typhoon season.
Nora formed from the monsoon trough that spawned a tropical depression east of the Philippines on October 1. Under weak steering currents, it meandered westward, where favorable conditions allowed for it to strengthen, first to a tropical storm on the 2nd, then to a typhoon on the 3rd. 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 877 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.
