Typhoon Paka (international designation: 9728, JTWC designation: 05C, PAGASA designation: Rubing, also known as Super Typhoon Paka) was the last tropical cyclone in the 1997 Pacific hurricane and typhoon season, and was among the strongest Pacific typhoons in the month of December.
Paka developed on November 28, 1997 from a trough well to the southwest of Hawaii. The storm tracked generally westward, and on December 7 it crossed into the western Pacific Ocean. Much of its track was characterized by fluctuations in intensity, and on December 10 it attained typhoon status as it crossed the Marshall Islands.
On December 16 Paka struck Guam and Rota with winds of 230 km/h (145 mph), and it strengthened further to reach peak winds on December 18 over open waters. Subsequently, it underwent a steady weakening trend, and on December 23 Paka dissipated.
