The 2021 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2021, with no seasonal boundaries, though most tropical cyclones typically develop between May and October. The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones, which can often result in a cyclone having two names. The Japan Meteorological Agency (JMA) names a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N, regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) are given a number with a "W" suffix.

During the year several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA and Taiwan's Central Weather Bureau. The first forecast was released by PAGASA on December 27, 2020, in their monthly seasonal climate outlook predicting the first half of 2021.[1] The PAGASA predicts that only 0–3 tropical cyclones are expected to form or enter the Philippine Area of Responsibility between January and March, while 1–4 tropical cyclones are expected to form between April and June. PAGASA also predicted that the ongoing La Niña could persist until the end of the first quarter of 2021.[1]

Seasonal summary

Systems

Tropical Depression Auring

Tropical depression (JMA)
 
DurationFebruary 16 – Present
Peak intensity<55 km/h (35 mph) (10-min);
1004 hPa (mbar)

At 12:00 UTC on February 16, the JMA reported that a tropical depression had formed.[2] The JTWC issued a Tropical Cyclone Formation Alert on the system just two hours later.[3]

The depression moved over Palau on February 16, bringing heavy rainfall to parts of the country.[4][5] At 3:00 UTC on February 17, the tropical depression moved into the Philippine Area of Responsibility, earning the name Auring from the PAGASA.[6]

Current storm information

As of 00:00 UTC February 17, Tropical Depression Auring is located near 6°54′N 134°36′E / 6.9°N 134.6°E / 6.9; 134.6 (Auring) Maximum 10-minute sustained winds are at <30 knots (55 km/h; 35 mph), with gusts up to <45 knots (85 km/h; 50 mph). The minimum central barometric pressure is 1004 hPa (29.65 inHg), and the system is moving westward slowly.

Other systems

During January 19, the JMA reported that a tropical depression had developed to the east of Luzon, Philippines.[7] The precursor to the depression brought scattered showers and thunderstorms to Mindanao, Palawan, and Visayas on January 18.[8] The JMA, however, discontinued advisories for the system on the next day.[9] The depression also brought stormy weather to Luzon on January 20. PAGASA warned residents of possible flash flooding and mudslides due to heavy rainfall.[10] The precursor of this system was associated from a frontal system, and its combined effects which brought heavy rainfall over much of Visayas, the Bicol Region, and Northern Mindanao resulted in one death and agricultural damages of up to ₱519.7 million (US$10.8 million).[11]

Storm names

See also: Tropical cyclone naming and History of tropical cyclone naming

Within the Northwest Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names.[12] The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65 km/h (40 mph).[13] PAGASA names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has had an international name assigned to it.[12] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee.[13] Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in gray.

International names

Main article: List of retired Pacific typhoon names

A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of 65 km/h (40 mph).[14] The JMA selected the names from a list of 140 names, that had been developed by the 14 members nations and territories of the ESCAP/WMO Typhoon Committee.[15] Retired names, if any, will be announced by the WMO in 2022; though replacement names will be announced in 2023. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.

Philippines

Main article: List of retired Philippine typhoon names

This season, PAGASA will use its own naming scheme, that will either develop within or move into their self-defined area of responsibility.[16] The names were taken from a list of names, that was last used during 2017 and are scheduled to be used again during 2025.[16] All of the names are the same except Uwan and Verbena which replaced the names Urduja and Vinta after they were retired.[16]
