With very warm waters, the system started to undergo a rapid deepening phase early on October 13 and reached its peak strength on the 17th.

The system developed into Tropical Depression 27W at late that day, moving in a west-northwesterly at 15 kn about 200 miles east of Guam.

On the October 13, the system developed into a tropical storm, and was named Tokage, subsequently moving very close to the islands of Rota and Guam.

The storm curled towards the north as a major shortwave over weakened the subtropical ridge and by October 17 Tokage reached its peak intensity of 125 kn/145 mph.

[2][3] By October 21, the cyclone weakened into a tropical storm 130 nm west of Tokyo, and later that day, the system completed the transition to a nontropical low.

[7] A total of 95 deaths were attributed to high winds, flooding and mudslides caused by Tokage, with an additional three people reported missing.
