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.[2] 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.[2]

Seasonal summary

Typhoon SurigaeTropical Storm Dujuan (2021)

The basin was quiet for the month of January, with only a minor tropical depression forming that did not cause much damage. By mid-February, a new tropical depression formed, and was named Auring by the PAGASA. The system then strengthened into a tropical storm, being given the name Dujuan by the JMA, which made it the first named storm of the year. Another tropical depression formed in March, though it was short-lived, dissipating shortly after forming. On April 12, a tropical depression formed to the south of Woleai. It strengthened into a tropical storm, being given the name Surigae by the JMA. On April 15, it was further upgraded into a severe tropical storm and then a typhoon, the first one of the season.

On 12:00 UTC of February 16, the JMA reported that a tropical depression had formed.[3] The JTWC issued a Tropical Cyclone Formation Alert on the system just two hours later.[4] By February 17, the system moved into the Philippine Area of Responsibility (PAR), earning the name Auring from the PAGASA.[5] At 09:00 UTC of the same day, the JTWC upgraded the system into a tropical depression, giving it the designation 01W.[6] On February 18, as it neared the Philippines, the JTWC and the PAGASA both upgraded the system to a tropical storm.[7][8] The JMA followed suit soon after, naming the storm Dujuan.[9] The PAGASA later upgraded Dujuan into a severe tropical storm; however, this only lasted for six hours.[10][11] On February 20, the storm significantly weakened due to high vertical wind shear, prompting the JTWC to downgrade the system back to a tropical depression.[12] However, the JTWC briefly re-classified the system as a tropical storm when the storm's structure improved.[13] By February 22, all agencies had downgraded the system to a tropical depression after the system's center had weakened prior to making landfall.[14][15][16] The JMA and the JTWC issued their final advisories moments after.[14][17] The storm made landfall over Batag Island in Laoang, Northern Samar at 09:00 PHT (01:00 UTC) on February 22,[18] and dissipated thereafter.[19]

Dujuan briefly moved over Palau on February 16 as a tropical depression, bringing heavy rainfall to parts of the country.[20][21] In anticipation of the storm, the PAGASA raised Signal #1 warnings for the eastern section of Mindanao on February 19, with the same warnings raised on the eastern provinces of Visayas.[22][23][24] Signal 2 warnings were also issued in the majority of Samar Island, Southern Leyte, the Dinagat Islands, and Surigao del Norte on February 21, prior to its landfall.[25] Classes and government work was suspended on February 22 in some places of Eastern Visayas and Central Visayas, including Surigao del Sur.[26][27] A total of 242,194 individuals were affected in Northern Mindanao, Caraga, and in the Davao Region. At least 77,811 of the affected individuals were taken to 344 various evacuation shelters in each region. One person was reported dead with four others reported missing, with total damages from agriculture and infrastructure amounting to ₱159.8 million (US$3.29 million).[28]

Main article: Typhoon Surigae

A low-pressure area south of Woleai developed into a tropical depression on April 12.[29][30] A few hours later, the JTWC issued a tropical cyclone formation alert for the developing storm, and the PAGASA also began issuing advisories for the tropical depression while it remained outside of the PAR.[31][32] On April 13, the JTWC upgraded the storm to a tropical depression and assigned it the designation 02W.[33] At 18:00 UTC, the JMA upgraded the cyclone into a tropical storm and named it Surigae.[34] On April 15 at 00:00 UTC, the JMA upgraded Surigae to a severe tropical storm as an eye began forming.[35] Later that day, the JTWC upgraded the storm to a typhoon, making it the first of the season. The JMA followed suit early on the next day, as a Central dense overcast developed and covered the original eye. As the storm continued to rapidly intensify, the JTWC upgraded the system to a Category 2-equivalent typhoon on the SSHWS.[36] The system continued it's rapid intensification until it reached Category 4 super typhoon status. The PAGASA also raised Tropical Cyclone Wind Signals #2 over parts of Visayas and Bicol.

After being named, tropical storm watches and warnings were issued for Yap in the Federated States of Micronesia, as well as for Koror and Kayangel in Palau, on April 14.[37] Warnings were eventually issued for Ngulu Atoll as well.[38] Winds of up to 30 mph (50 km/h) were recorded in Yap on that day as Surigae passed from the southwest.[39] On April 16, as the storm tracked towards the Philippines, the PAGASA issued Signal #1 warnings for areas around the country, and Signal #2 warnings the next day for Catanduanes and the entire island of Samar.[40][41][42]

Current storm information

As of 06:00 UTC April 17, Typhoon Surigae is located near 11°24′N 130°12′E / 11.4°N 130.2°E / 11.4; 130.2 (Surigae), about 392 nmi (725 km; 450 mi) east south east of Legazpi, Philippines. Maximum 10-minute sustained winds are at 100 knots (185 km/h; 115 mph) with gusts up to 140 knots (260 km/h; 160 mph), while maximum 1-minute sustained winds are at 130 knots (240 km/h; 150 mph). The minimum central barometric pressure is 925 hPa (27.32 inHg), and the system is moving north west at 12 kn (20 km/h; 15 mph).

Other systems

A tropical depression on January 19

During January 19, the JMA reported that a tropical depression had developed to the east of Luzon, Philippines.[43] The precursor to the depression brought scattered showers and thunderstorms to Mindanao, Palawan, and Visayas on January 18.[44] The JMA, however, discontinued advisories for the system on the next day.[45] The depression also brought stormy weather to Luzon on January 20. The PAGASA warned residents of possible flash flooding and mudslides due to heavy rainfall.[46] 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 three deaths and agricultural damages of up to ₱642.5 million (US$13.2 million).[47]

On March 9, a low-pressure area entered the Philippine Area of Responsibility, though it was not expected to develop at that time.[48][49] On March 14, the low-pressure area intensified into a tropical depression over the Sulu Sea but quickly degenerated back into a low-pressure area.[50][51] The system brought light to moderate rains over parts of the Philippines, with the PAGASA advising residents of the possibility of floods and landslides.[52]

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.[53] 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).[54] 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.[53] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee.[54] 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).[55] 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.[56] 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. During the season, the name Surigae was used for the first time after it replaced Mujigae in the 2015 season.
