2022 Pacific typhoon season

Tropical depression (JMA)
Tropical depression (SSHWS)
Duration	March 29 – March 31
Peak intensity	<55 km/h (35 mph) (10-min)  1006 hPa (mbar)

A disturbance that formed after crossing the Visayas region and Palawan on late March developed into a low-pressure area southeast of Da Nang, Vietnam. It then developed into a tropical depression, the first one of the 2022 Pacific typhoon season, at 18:00 UTC on March 29.[4] At 21:00 UTC the same day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) for the system.[5] On the next day, the agency upgraded to a tropical depression, assigning it the designation 01W. Shortly after, they issued their final advisory on the system after it eventually struck in the southeastern part of Vietnam on March 30.[6]

In Vietnam, floods caused by the depression have killed 6 people, left 1 missing and 8 injured. Flooding also caused 2 houses to collapse, 50 houses to lose their roofs, 229 boats to sink, and 2,592 rafts to be damaged.[7]

Very strong typhoon (JMA)
Category 4 typhoon (SSHWS)
Duration	April 6 – April 15
Peak intensity	155 km/h (100 mph) (10-min)  950 hPa (mbar)

The JTWC first noted the existence of a tropical disturbance on April 3.[8] Favorable conditions near the system helped it develop, with the JMA recognizing the system as a tropical depression on April 6.[9] Later in the day, the JTWC issued a TCFA for the system.[10] The following day, the JTWC recognized the system as a tropical depression and gave it the designation 02W.[11] At 21:00 UTC, the JTWC then upgraded it to a tropical storm.[12] On April 8, the system developed into a tropical storm and was named Malakas by the JMA.[13] Malakas continued traveling over the Pacific Ocean, and began to slowly intensify, becoming a severe tropical storm on the April 11, then a typhoon by April 12.[14][15] At around the same time, it entered the Philippine Area of Responsibility (PAR), receiving the local name of Basyang from the PAGASA at 03:00 UTC.[16] Malakas then lingered for a while at the border of the PAR before eventually exiting 5 hours later,[17] while intensifying into a Category 2-equivalent typhoon. Malakas then continued its intensification, reaching Category 3-equivalent status on the morning of April 13, and Category 4-equivalent typhoon at noon that day, reaching its peak intensity. The following day, Malakas weakened to a Category 3-equivalent typhoon as its eye structure degraded. It further weakened to Category 1 status later in the day. By 15 April, it began its transition into an extratropical cyclone while having a rapid weakening. The JTWC gave final warning on the system on 09:00 UTC of same day while JMA did the same around 18:00 UTC.

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	April 8 – April 13
Peak intensity	65 km/h (40 mph) (10-min)  998 hPa (mbar)

On April 8, the JTWC noted the persistence of an area of convection 359 nautical miles (665 km; 413 mi) west-northwest of Palau.[18] Since the storm's conditions were favorable for development, the JMA included the storm in its weather summary as a tropical depression off the coast east of Visayas later that day.[18][19] Around the same time, the PAGASA announced that the system had developed into a tropical depression, was named Agaton by the agency.[20] The PAGASA began issuing Tropical Cyclone Bulletins (TCBs) for the storm later that day.[21] On the next day, the JTWC later issued a TCFA for the system.[22] At 03:00 UTC, the agency upgraded it to a tropical depression and assigned it the identifier 03W.[23] On April 10, the JMA upgraded it to a tropical storm, assigning it the name Megi.[24] It made its first landfall in Calicoan Island, Guiuan at 07:30 PHT (23:30 UTC).[25] Megi then stalled in the Leyte Gulf for hours before making its second landfall in Basey, Samar.[26] Megi then weakened into a tropical depression after lingering over the islands of Samar and Leyte, and the PAGASA removed all warning signals as it dissipated into a remnant low on the midnight of April 13.[27]

From April 8 to April 10, the storm meandered along the Eastern Visayas region, dumping heavy rain on the region.[28] The PAGASA raised storm signals up to Signal No. 2 during the storm's onslaught.[29][30] Cebu City was placed under a state of calamity following the heavy rain.[31] Megi killed 214 people which effectively made it the deadliest April tropical cyclone on record in the Philippines,[32][33] injured eight people,[34] and capsized a cargo boat in Ormoc following strong rains, winds, and flash floods that also displaced over 136,390 individuals.[35] The governor of Davao de Oro estimated the agricultural damages in the province at ₱4.72 billion (US$90.8 million).[36]

A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of 65 km/h (40 mph).[39] 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.[40] Retired names, if any, will be announced by the WMO in 2023; though replacement names will be announced in 2024. 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, that will either develop within or move into their self-defined area of responsibility.[41] The names were taken from a list of names, that was last used during 2018 and are scheduled to be used again during 2026.[41] All of the names are the same except Obet, Rosal and Umberto which replaced the names Ompong, Rosita and Usman after they were retired.[41]
