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.

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] Later that day, the PAGASA began to issue advisories for the system, which the agency declared a tropical depression.[4] At 00:00 UTC on February 17, the tropical depression moved into the Philippine Area of Responsibility, earning the name Auring from the PAGASA. This made Auring the first storm of the season to be named by the PAGASA.[5] At 09:00 UTC February 17, the JTWC upgraded the system into a tropical depression, giving it the designation 01W.[6]
The depression moved over
Current storm information
As of 21:00 UTC February 17, Tropical Depression 01W (Auring) is located near 6°42′N 132°30′E / 6.7°N 132.5°E, or about 422 nautical miles (780 km; 485 mi) east of Davao, Philippines. Maximum 10-minute sustained winds are at 30 knots (55 km/h; 35 mph), while maximum 1-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 1002 hPa (29.59 inHg), and the system is moving westward slowly.

Unnamed Tropical Depression
During January 19, the JMA reported that a tropical depression had developed to the east of Luzon, Philippines.[9] The precursor to the depression brought scattered showers and thunderstorms to Mindanao, Palawan, and Visayas on January 18.[10] The JMA, however, discontinued advisories for the system on the next day.[11] The depression also brought stormy weather to Luzon on January 20. PAGASA warned residents of possible flash flooding and mudslides due to heavy rainfall.[12] 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).[13]

International names
A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of 65 km/h (40 mph).[16] 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.[17] 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
This season, PAGASA will use its own naming scheme, that will either develop within or move into their self-defined area of responsibility.[18] The names were taken from a list of names, that was last used during 2017 and are scheduled to be used again during 2025.[18] All of the names are the same except Uwan and Verbena which replaced the names Urduja and Vinta after they were retired.[18]
