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.

Tropical storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center.

The next day the depression strengthened into a tropical storm and was named Rita by the Joint Typhoon Warning Center.

[2] At this time a cold front to the north and a subtropical ridge positioned behind it forced the storm to turn sharply to the north-northeast.

[4] Rita stayed largely at sea with little to minor effects to Palau or to the Mariana Islands, besides some rain and squally weather.

Alice quickly strengthened and passed directly over Hong Kong with gusts of 85 mph on the 18th before recurving through the Chinese Mainland.

[5] 20 people were killed from heavy rain and mudslides, when 90 mph Typhoon June hit southeastern Taiwan on August 6.

Typhoon Olga made landfall 50 kilometers to the northeast of Hong Kong, killing 7 people, mostly due to landslides.

Tropical Storm Nancy, having developed on September 7 in the open West Pacific, rapidly intensified to reach super typhoon status early on the 9th.

Well executed warnings lessened Nancy's potential major impact, but the typhoon still caused 172 fatalities and widespread damage.

It caused 11 deaths, over $6 million in crop damage, and the Lebanese merchant ship Sheik ran aground off of Kitadaitōjima, killing 2.

After a few days of observation, a report of tropical-storm-force winds was relayed back to the JTWC and on October 4, it was upgraded to Tropical Storm Violet.

Violet moved in a smooth path northward and clipped the Boso Peninsula area of Japan, near Tokyo.

The system moved to the southwest, neared the coast of Vietnam, but abruptly turned in the opposite direction on October 8.

Wilda reached a peak intensity of 70 mph (115 km/h) and a minimal surface pressure of 990 hPa (29 inHg) before making landfall on Vietnam.

It traveled in a generally westward direction over the South China Sea, and intensified into a tropical storm later that day.

[15] The remaining moisture may have helped aid the development of a tropical depression, on October 22, near present-day Rakhine.

The first warning was issued by the JTWC on October 23, by that time the cyclonic radius extended over 1,000 nautical miles from the center.

[11] By this time, October 26, Billie had reached a peak intensity of 80 mph (130 km/h) and a minimal surface pressure of 961 hPa (28.4 inHg).

Gradually intensifying as it moved to the northeast, the first warning was issued by the JTWC on October 26 as sea surface reports indicated Clara was a tropical storm.

[11] The origin of Dot can be traced back to a compact low-pressure center over open water to the east of Guam on November 7.

Initially, it wasn't until November 9 that when pilots traversing the Pacific reported the existence of an area of severe weather to the northeast of Guam.

It was likely, due to the small size of Dot, that it would not have been discovered before it reached the Mariana Islands, had it not passed through a route used by trans-Pacific aircraft.

[11] Dot moved in a near westward direction after being discovered, passed through the Mariana Islands, and gradually intensifying into a category five super typhoon to the northwest of Guam.

[11] The extra-tropical low traversed the rest of the Pacific Ocean and made landfall over Southern California on November 20.

[11] The extra-tropical low of Dot dumped one to five inches of rain over the Southwest U.S. and contributed to excessive rainfall over the New England area.

The low developed into a tropical depression with well-defined spiral storm bands and a closed circulation early on December 5.

By December 11, the typhoon reached secondary peak intensity, and small hail was observed within the eye during this time.

[23] A Panamanian freighter carrying logs to Hong Kong sank in the South China Sea, near the Spratly Islands, due to squally weather on December 9.
