The 2000 Pacific typhoon season marked the first year using names contributed by the World Meteorological Organization.

Tropical depressions monitored by the United States' Joint Typhoon Warning Center (JTWC) are given a number with a "W" suffix.

The JTWC also issued warnings on storms within the basin, operating from Pearl Harbor in Hawaii and supplying forecasts to the United States Armed Forces in the Indian and Pacific Oceans.

The first storm of the season started out as a tropical low near Palau on May 3, when the JTWC first gave the system a poor chance of formation.

On May 17 the low pressure area started to drift across the northern Philippines, and rapidly intensified into a tropical storm before quickly dissipating due to vertical wind shear on May 20.

A vortex in an active trough over the South China Sea developed into a small tropical depression on June 18, 35 km south-southwest of Hong Kong.

It moved northward and made landfall that day, with its very small circulation being well captured by the Observatory's network of automatic weather stations.

[8] On June 30, an area of disturbed weather was identified roughly 650 km (405 mi) east of the Philippine island of Mindanao.

Tracking northward, the system intensified into a tropical storm, at which time it received the name Kirogi, before undergoing rapid intensification late on July 3.

Following this phase, the storm attained typhoon intensity and developed a well-defined 59 km (37 mi) wide symmetrical eye.

Typhoon Kirogi attained its peak intensity early on July 4 with winds of 155 km/h (100 mph 10-minute sustained) and a barometric pressure of 940 mbar (hPa; 27.76 inHg).

The combined effects of Kai-tak and Tropical Depression Gloring led to the collapse of a large garbage pile, devastating a scavenger community with 300 shanty homes near Manila.

On July 22 convection was displaced to south of the storm's center due to high wind shear, and caused it to dissipate.

Also, since Upana had dissipated several days earlier, and the Joint Typhoon Warning Center had already assigned a new number for the system, Gary Padgett deemed it likely that the Japan Meteorological Agency's decision to rename the cyclone was the best choice.

Also, a scatterometer pass near 0500 UTC on July 23 indicated an open wave with no closed circulation,[13] evidence that Upana had fully dissipated before restrengthening.

On July 29, a cluster of thunderstorms quickly formed into a low pressure area, which became Tropical Depression 13W on August 1.

On August 6, Jelawat restrengthened into a category 3 typhoon due to more favorable conditions, and started to develop a large eye which was 60 kilometers across.

On August 7, Jelawat underwent an eyewall replacement cycle for 4 hours, and began to display annular characteristics, with a large, symmetric eye 170 kilometers across surrounded by a thick ring of intense convection.

The typhoon re-intensified, but dissipated on August 18.A tropical disturbance developed in the Western Pacific Ocean along the eastern periphery of the monsoon trough in mid-August.

It moved eastward along the west- east oriented surface pressure trough, and crossed the International Date Line later on the 15th.

[14] Warmer than usual water temperatures allowed the system to intensify despite its unusually high latitude, and it became Tropical Storm Wene on the 16th.

It quickly attained a peak intensity of 50 mph, but weakened due to cooler waters and wind shear.

No victims were recorded during the storm's short lifespan.On August 14, a low pressure area formed south of the Mariana islands and started to organize.

Prapiroon killed 75 people in total and caused $6 billion in damages in Korean peninsula, China and the Philippines.

Peaking as a typhoon with winds of 130 km/h (80 mph), Yagi executed a cyclonic loop near the Ryukyu Islands.

It turned to the north over the South China Sea, and after strengthening to a 100 mph typhoon it hit Taiwan.

Xangsane dissipated on Nov. 1st, after causing 181 casualties, 83 of which were from the crash of Singapore Airlines Flight 006 the previous day on October 31, 2000.

Within the North-western Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility.

This table will list all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 2000.
