2017 Planet X Pacific typhoon season

For Planet X, 2017 featured the 2017 Pacific typhoon season. It had no official seasonal boundaries, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the Equator and west of the International Date Line. Storms that form east of the Date Line and north of the Equator are called hurricanes. Tropical storms forming across the entire West Pacific basin were assigned a name by the Joint Typhoon Warning Center (JTWC). Tropical depressions in this basin have the "W" suffix added to their number by the JTWC.

During the season, 66 areas of investigation and 36 total tropical depressions developed. All of the tropical depressions further intensified into nameable tropical storms, with 31 of them further intensifying into typhoons, and an additional 11 typhoons became super typhoons (a typhoon with 150 miles per hour (mph) winds or greater). These numbers all represent record highs for the basin; this can partially be attributed to the JTWC deploying more weather satellites across the Pacific this year than previous years, meaning the agency could now collect more data than it previously could from active storms across the basin.

Impactwise, the 2017 Planet X Pacific typhoon season was a devestating year for China, the Philippines, Japan, and Korea. Many areas suffered more damage and deaths this season than in previous years, although overall statistics during the season are unknown.

Season summary
Timeline of tropical activity in 2017 Planet X Pacific typhoon season

Super Typhoon Wilbur
Typhoon Wilbur caused mass landslides across Japan.

Super Typhoon James
Typhoon James battered Hong Kong with fierce hurricane-force winds.

Super Typhoon Paolini
Typhoon Paolini sank hundreds of ships anchored around Shanghai and Seoul.

Super Typhoon Quinn
Typhoon Quinn resulted in the first loss of a Hurricane Hunter aircraft on Planet X (the next storm to do so would be Typhoon Joachim the following year) and trashed shipping ports around Manila. In addition, it was the strongest storm ever recorded on Planet X, although records before 2015 are unreliable.

Storm names
The following names were used to name storms that attained gale-force intensity in the Western Pacific tropical cyclone basin during 2017. The first storm of the season was named Nemo and the last one Wolfgang. Names that were not assigned this year are marked in.

 NOTE: Unless otherwise stated, all names on both lists are masculine.
