Pacific typhoon seasons
2022, 2023, 2024, 2025, 2026

The 2024 Pacific typhoon season is the fifth-latest start for a Pacific typhoon season since reliable records began. It is an ongoing event in the annual cycle of tropical cyclone formation in the western Pacific Ocean. The season runs throughout 2024, 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)[nb 2] will name a tropical cyclone if it has 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in the Philippine Area of Responsibility (PAR), located between 135°E and 115°E and between 5°N–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)[nb 3][nb 1] 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.

Tropical Storm Risk (TSR) released their first forecast on May 7, predicting below average activity with 25 named storms, 15 typhoons and 7 intense typhoons. This was primarily due to the dominant El Niño event at time, which was expected to transition into a weak or moderate La Niña by mid-2024.[3]

Seasonal summary[edit]

Typhoon Ewiniar (2024)

The Pacific typhoon season began abnormally late, with no systems forming for five months until May 22, when a tropical storm named Ewiniar formed southeast of Palau, marking it as the fifth-latest start of a Pacific typhoon season since reliable records began.[4] Ewiniar went straight to the Philippines to make nine landfalls in Homonhon Island; Giporlos, Eastern Samar; Catbalogan, Samar; Batuan, Masbate; Masbate City; Torrijos, Marinduque; Lucena, Quezon and Patnanungan. It began to move over the warm tropical waters of Lamon Bay, where JTWC upgraded Ewiniar into a Category 1-equivalent typhoon.

On May 21, the Joint Typhoon Warning Center (JTWC) began to monitor an area of atmospheric convection 441 km (274 mi) southeast of Palau, noting that the system was moving northwestward towards an environment favorable for tropical cyclogenesis, characterized by sea surface temperatures of 29–30 °C (84–86 °F), low vertical wind shear, and moderate to strong outflow.[5] The JTWC subsequently issued a Tropical Cyclone Formation Alert (TCFA) on the following day as the disturbance developed rainbands wrapping from the southwest.[6] At 18:00 UTC, the Japan Meteorological Agency (JMA) recognized the system as a tropical depression.[7] Early on May 23, the depression entered the Philippine Area of Responsibility (PAR).[8] In the early morning of May 24, Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) upgraded the system from a low-pressure area into a depression, assigning it the local name Aghon.[9] At 18:00 UTC, the JTWC upgraded the system to Tropical Depression 01W based on surface observations from Guiuan.[10] Aghon made landfall over Homonhon Island and subsequently Giporlos, Eastern Samar in the early morning of May 25 (PHT).[11] In the evening, it made five more landfalls over Basiao and Cagduyong Islands of Catbalogan; Batuan in Ticao Island; Masbate City; and Torrijos, Marinduque.[12] At 12:00 UTC, the JTWC reported that the tropical depression had intensified into a tropical storm while it was still in Tayabas Bay.[13] The JMA then classified the system as a tropical storm the following day, assigning it the name Ewiniar.[14] In the morning of May 26 (PHT), the storm made its eighth landfall over Lucena, Quezon in Luzon island.[12] The JTWC upgraded Ewiniar into a Category 1-equivalent typhoon after satellite imagery showed that its eye feature was developing over the warm waters of Lamon Bay.[15][16] In the evening, the storm made its ninth landfall over Patnanungan in the Polillo Islands.[17] The next day, the JMA upgraded Ewiniar into a typhoon.[18]

Seven people were injured and around 19,000 others were directly impacted by Aghon in the Philippines.[19] Three people, including an infant, died in Quezon.[20] A falling tree destroyed two vehicles in Taytay, Rizal.[21] Nineteen houses were washed away by strong waves in Tanza, Cavite.[22] Flooding and power outages occurred in Quezon and Laguna Provinces, while a barge ran aground in Mauban.[23][24] A power outage occurred in parts of Eastern Samar.[25] Damage to infrastructure; estimated at ₱320 million (US$6.5 million).[26]

Current storm information[edit]

As of 18:00 UTC May 27, Typhoon Ewiniar (Aghon) is located near 18°06′N 124°54′E / 18.1°N 124.9°E / 18.1; 124.9 (Ewiniar) or about 566 nautical miles (1,050 km; 650 mi) south-southwest of Kadena Air Base. Maximum 10-minute sustained winds are at 65 knots (120 km/h; 75 mph), with gusts up to 95 knots (175 km/h; 110 mph), while maximum 1-minute sustained winds are at 80 knots (150 km/h; 90 mph). The minimum central barometric pressure is 985 hPa (29.09 inHg), and the system is moving north-northeast slowly.

Storm names[edit]

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

Within the basin, 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.[27] 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 when they have 10-minute sustained winds of 65 km/h (40 mph).[28]

PAGASA names tropical cyclones which are active in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has already been named.[27] The names of significant tropical cyclones are retired by both PAGASA and the Typhoon Committee.[28] If the list of names for the Philippine region are 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. The names of significant tropical cyclones will be retired by both PAGASA and the Typhoon Committee in the spring of 2025.[28]

International names[edit]

Main article: List of retired Pacific typhoon names

A tropical cyclone is named when it has 10-minute sustained winds of 65 km/h (40 mph).[29] 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.[30] Retired names, if any, will be announced by the WMO in 2025, though replacement names will be announced in 2026. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.

This season, PAGASA will use its own naming scheme for storms that are active in their self-defined area of responsibility.[31] During this season, PAGASA is using the following list of names that was last used during 2020 and will be used again in 2028, updated with replacements of retired names, if any.[31] All of the names are the same as in 2020 except Aghon, Querubin, Romina and Upang, which replaced the names Ambo, Quinta, Rolly and Ulysses after they were retired.[31] The name Aghon was used for the first time this year.
