The 2025 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation in the western Pacific Ocean. The season will run throughout 2025, 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 1] 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 2][nb 3] are given a number with a "W" suffix; W meaning west, a reference to the western pacific region.

Seasonal summary

Systems

Other systems

A tropical depression active on 11 February.
  • On February 11, the Japan Meteorological Agency (JMA) noted that a tropical depression had formed west of the Philippines.[3] The next day, the Joint Typhoon Warning Center (JTWC) began tracking the system around 267 nautical miles (494 km) west-northwest of the Spratly Islands, noting that it was in an unfavorable environment for development, with significant wind shear of 25–30 mph (35–45 km/h) and marginal sea surface temperatures (SSTs) of 26 °C (79 °F).[4] As a result, the JTWC stopped tracking the system the next day, noting that it had dissipated.[5] The JMA kept tracking the depression until it dissipated on February 15.[6] Although, it regenerated the next day,[7] the JMA stopped tracking it by February 17.[8]
    Alongside a low-pressure trough passing through Vietnam, rains from the depression caused several regions in the southeastern parts of the nation to break unseasonal rain records for the month of February, with Ho Chi Minh City recording its heaviest rainfall in the past 20 years. In the town of Long Thanh, 175 mm (6.9 in) was recorded.[9] Some towns, like Nhà Bè, saw their highest rainfall in 41 years.[10] On Hon Doc Island, rainfall reached 128.2 mm (5.05 in) in the early morning of February 16, the highest in the Southwest region on record.[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. The names of significant tropical cyclones will be retired by both PAGASA and the Typhoon Committee in the spring of 2025.[13]

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 2026, though replacement names will be announced in 2027. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used. All the names in the list are the same, except for Co-May, Nongfa, Ragasa, Koto and Nokaen, which replaced Lekima, Faxai, Hagibis, Kammuri, and Phanfone respectively after the 2019 season.

Philippines

Main article: List of retired Philippine typhoon names

This season, PAGASA will use its own naming scheme for storms that develop in or enter their self-defined area of responsibility.[16] During this season, PAGASA is using the following list of names, that was last used during 2021 and will be used again in 2029, updated with replacements of retired names, if any.[16] All of the names are the same as in 2021 except Jacinto, Mirasol and Opong, which replaced the names Jolina, Maring and Odette after they were retired.[16]
