Typhoon Ivan, known in the Philippines as Typhoon Narsing, was an intense tropical cyclone that existed simultaneously with another storm of the same intensity, Typhoon Joan, in October 1997. Forming out of an area of disturbed weather on October 13, Ivan gradually intensified into a typhoon as it tracked steadily to the west-northwest. On October 15, the storm underwent rapid intensification and reached an intensity corresponding to Category 5 status on the Saffir–Simpson Hurricane Scale. Late on October 17, Ivan reached its peak strength with winds of 295 km/h (183 mph) and a barometric pressure of 905 hPa (mbar). Shortly thereafter, the typhoon began to weaken as it approached the Philippines. Ivan eventually made landfall in northern Luzon with winds of 220 km/h (140 mph) on October 20 before weakening to a tropical storm the next day. The storm then curved northeastward and became extratropical on October 25 and dissipating the following day.
Although Ivan was a powerful storm at landfall, its effects were relatively minor compared to the storms' intensity; however, 14 people were killed during the storm and two others were listed as missing. Agricultural industries sustained the most severe damage, as thousands of animals drowned in the storm. Total damage was estimated at $9.6 million (1997 USD; $13.1 million 2009 USD). A total of 1,779 homes were destroyed, 13,771 others were damaged and 4,600 hectares of farmland were flooded by the storm.
