Typhoon Paka first impacted the Marshall Islands, where it dropped heavy rainfall and left $80 million in damage (1997 USD, $100 million 2007 USD). Later, it passed just north of Guam, where strong winds destroyed about 1,500 buildings and damaged 10,000 more; 5,000 people were left homeless, and the island experienced a complete power outage following the typhoon. Damage on the island totaled $500 million (1997 USD, $645 million 2007 USD), which warranted the retirement of its name. Paka also caused light damage in the Northern Mariana Islands

s across the area, forecasters had difficulty at times in locating the low-level circulation. After becoming a tropical storm, Paka remained nearly stationary for about two days before resuming a slow motion to the west-southwest. It steadily intensified due to warm water temperatures, and on December 3 the storm attained winds of 105 km/h (65 mph). The next day, however, it encountered dry air and began weakening; by December 6, the winds had decreased to minimal tropical storm status for about 12 hours. Subsequently, Paka began to re-intensify, and on December 7 the storm crossed the International Date Line

, and that night the JTWC upgraded Paka to typhoon status. Paka officially attained typhoon status when JMA classified it with winds of 120 km/h (75 mph) at 0000 UTC on December 11.

After attaining typhoon status, Paka strengthened fairly quickly, and by December 12 it reached sustained winds of 150 km/h (90 mph) for a ten-minute (10 min) duration, or 215 km/h (135 mph) over a one-minute (1 min) duration. Subsequently, it briefly weakened as its forward motion increased. However, Paka again re-intensified, and at 1200 UTC on December 14 it attained the unofficial ranking of super typhoon status while over the open Pacific Ocean. At the same time, the JMA classified it with 10 min sustained winds of 175 km/h (110 mph).

Typhoon Paka continued to steadily intensify after passing the Marianas Islands, and late on December 17 it reached its peak intensity of 185 km/h (115 mph 10 min sustained) while located 440 km (275 mi) west-northwest of Guam.

The strong winds from Paka left around 1,500 buildings destroyed on the island, of which 1,160 were single-family homes. A further 10,000 buildings sustained damage to some degree, with 60% of the homes on the island reporting major damage. In all, about 5,000 people were left homeless due to the typhoon.
