The 2023 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 2023, though most tropical cyclones typically develop between May and October. The season's first named storm, Sanvu, developed on April 21. The season's first typhoon, Mawar, reached typhoon status on May 21.

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 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 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.

Seasonal summary

Typhoon Mawar

The first two months were inactive, with no tropical cyclones formed. It started with a tropical depression on March 4, being the first system of the season, formed to the east of Singapore designated as 98S by the JTWC due to the agency analyzing the system as being located within the Southern Hemisphere.[5] It killed at least four people.[6] In early April, a depression formed and was named Amang, which became the first named storm by PAGASA. It made its first landfall in Panganiban, Catanduanes around 23:00. It made its second landfall over Presentacion, Camarines Sur and in the vicinity of Lagonoy, Camarines Sur later that day.[7] It was downgraded to a low on April 13 because of unfavorable conditions including dry air and high wind shear. Amang caused over ₱12.3 million (US$222 thousand)[nb 4] of agricultural damages throughout its path.[8] Another tropical depression formed on April 19, with JTWC giving it a high chance of developing into a tropical cyclone.[9] The agency upgraded the system to a tropical storm on April 20 and three hours later, the JMA assigned the name Sanvu, making it the first named storm of the season. Sanvu began to weaken on April 22 due to clusters of convection on its northeast quadrant absorbing its energy. The JTWC subsequently ceased issuing bulletins on the storm.

In early May, a tropical disturbance developed around 745 km (460 mi) east of Davao City, naming it as Invest 93W by the JTWC. The convection continued to broaden as it wrapped around the disorganized low pressure area. However, land interaction and the system's weak structure hindered further development, despite being in favorable environmental conditions.[10] Later on May 5, the JMA classified the disturbance as a tropical depression.[11] However, chances of being a tropical cyclone downgraded to low due to of presence of dry air and weak outflow before it dissipated on May 7.[12] A low-pressure area formed south-southwest of Chuuk Islands and then developed into a tropical depression on May 19.[13][14] It was later designated as 02W by the JTWC and named the storm "Mawar" a few hours later by the JMA before it intensified into a severe tropical storm on the next day. As it entered more favorable conditions and low wind shear, it was upgraded into category 1-equivalent typhoon by the JTWC. JMA followed suit and upgraded Mawar to Typhoon status at 03:45 UTC on May 21[15]

Systems

Tropical Depression Amang

Tropical depression (JMA)
 
DurationApril 10 – April 13
Peak intensity55 km/h (35 mph) (10-min);
1004 hPa (mbar)

The JMA first noted a low-pressure area in the Philippine Sea on April 7.[16] A strong convection to the north of the system's low-level circulation center (LLCC) prompted the JTWC to first issue a Tropical Cyclone Formation Alert (TCFA) on the disturbance as it tracked west-northwestwards into a favorable environment for further development.[17] Later that day, the JMA and the PAGASA classified the storm as a tropical depression.[18][19] As the storm formed within the Philippine Area of Responsibility (PAR), the depression received the name Amang.[19] Amang made its first landfall over Panganiban, Catanduanes around 23:00 PHT (15:00 UTC) on April 11.[20] Later the next day, the PAGASA reported that Amang had made a second landfall in Presentacion, Camarines Sur and later made its third landfall in Lagonoy, Camarines Sur.[21] Upon land interaction, the JTWC canceled its TCFA, stating that Amang had reached more unfavorable conditions including dry air and wind shear.[22] PAGASA downgraded the storm to a low on April 13.[23]

Agricultural damages caused by the storm were estimated at ₱12.3 million (US$222 thousand), affecting 1,324 farmers and 1,096.6 hectares (2,710 acres) of land.[24] 1,918 passengers were stranded in the Bicol Region following sea travel suspensions.[25] On April 13, classes up to senior high school in 19 areas were suspended due to bad weather, along with pre-elementary classes in areas under Signal No. 1.[26]

Tropical Storm Sanvu

Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationApril 19 – April 25
Peak intensity85 km/h (50 mph) (10-min);
998 hPa (mbar)

An area of convection monitored by the JTWC spawned south-southeast of Pohnpei on April 18.[27] The JMA later classified the disturbance as a tropical depression the following day,[28] before the JTWC followed suit and designated the system 01W.[29] On April 20, the depression further intensified to a tropical storm, according to the JTWC,[30] after convection and rainbands strengthened over the LLCC.[31] The JMA subsequently upgraded its status by 6:00 UTC, and gave the name Sanvu to the storm.[32] After reaching its peak intensity early on April 21, Sanvu began to weaken afterward due to clusters of convection on its northeast quadrant absorbing its energy.[33] By April 22, Sanvu's poor, ragged structure of its circulation center prompted the JTWC to cease issuing bulletins on the storm as it was downgraded to a tropical depression.[34] The JMA cancelled advisories on the storm the same day as well.[35] The JMA tracked the system until 00:00 UTC of April 25.[36] The JTWC reported that Sanvu's remnants had dissipated on April 26.[37]

Main article: Typhoon Mawar

A low-pressure area south-southwest of Chuuk Islands developed into a tropical depression on May 19.[13][14] On May 20, it was later designated as 02W by the JTWC and named the storm Mawar a few hours later by the JMA before it intensified into a severe tropical storm on the next day. As it entered more favorable conditions and low wind shear, it was upgraded into Category 1-equivalent typhoon by the JTWC. The JMA followed suit and upgraded Mawar into a typhoon.[38] The storm was further upgraded to Category 2-equivalent status by the JTWC on May 22. It later reached Category 3-equivalent status on the same day. On the same day, the PAGASA forecasted that Mawar is likely to develop into a super typhoon.[39][40] A couple of hours later, the JTWC updated Mawar into a Category 4-equivalent typhoon while JMA keeping it as a very strong typhoon status. On May 23 of 4:00 PM, PAGASA and JTWC reported that Mawar intensified into a super typhoon.[41][42][43] On May 25, Mawar reached Category 5 super typhoon status.[44][45] At 2 am on the next day, the super typhoon entered PAR, assigning the local name Betty.[46] [47]

Current storm information

As of 00:00 UTC May 27, Typhoon Mawar (Betty) is located near 16°24′N 133°30′E / 16.4°N 133.5°E / 16.4; 133.5 (Mawar) or about 441 nautical miles (815 km; 505 mi) north-northwest of Yap. 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 135 knots (250 km/h; 155 mph). The minimum central barometric pressure is 925 hPa (27.32 inHg), and the system is moving west at 15 kn (28 km/h; 17 mph).

A tropical depression over Palawan on 5 May.

According to the JMA, a tropical depression formed to the east of Singapore on March 4.[48] It was designated 98S by the JTWC shortly afterwards, due to the agency analyzing the system as being located within the Southern Hemisphere.[49] The system was last noted on March 7.[50] 50,000 people were affected in Malaysia from the floods produced by the system, which also killed four people.[6]

On May 1, a tropical disturbance persisted around 740 km (460 mi) east of Davao City and had fragmented but organized rainbands to the north and west of its circulation center.[51] The convection continued to broaden as it wrapped the disorganized LLCC. However, land interaction with the Philippines and the system's weak structure hindered further development, despite being in favorable environmental conditions.[52] On May 5, the JMA classified the disturbance as a tropical depression.[53] However, dry air and a weak outflow aloft showed that the depression had very little development, all while tracking west-northwestward.[54] The depression later dissipated by May 7.[55][56]

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.[57] 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).[58] 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.[57] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee.[58] 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).[59] 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.[60] Retired names, if any, will be announced by the WMO in 2024; though replacement names will be announced in 2025. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.
