Typhoon Betty, known in the Philippines as Typhoon Aring, was the strongest typhoon to strike the Philippines in ten years. An area of disturbed weather developed on October 27, 1980, near Truk Atoll. After turning east from south, the disturbance was classified as a tropical storm on October 29 as it passed near Guam, causing only minor damage. Following a turn to the west-northwest, Betty attained typhoon intensity the next day. On November 4, Betty peaked in intensity. Later that day, Betty moved ashore over Luzon, introducing a rapid weakening trend. Over land, Betty then began to turn north due to a weakening subtropical ridge to its north and a trough offshore Taiwan. By November 8, Betty, after moving offshore, had completed its transition into an extratropical cyclone, and dissipated that same day.
Across the Philippines, 101 casualties were reported. More than 29,000 homes were damaged and over 5,000 houses were leveled, resulting in 229,000 people homeless. A total of 70 villages sustained flooding. In all, Typhoon Betty inflicted $181 million (1980 USD) in damage, with $43.1 million from crops, $116 million from public property, and $21.7 million from private property.[nb 1] Following the storm, 11 provinces were declared a disaster area.
