Being the thirteenth named storm of the said event, Conson originated as a low-pressure area first monitored approximately 500 km (310 mi) west of Guam.

The storm retained its strength as it crossed Visayas and later Calabarzon before weakening over Manila Bay prior to its final landfall in Bataan.

The National Disaster Risk Reduction and Management Council in the Philippines reported 23 deaths, 32 injuries and 2 missing individuals.

At 06:00 UTC of September 5, the United States Joint Typhoon Warning Center (JTWC)[nb 1] started to monitor a tropical disturbance in the Philippine Sea, located about 446 nmi (513 mi; 826 km) to the east-southeast of Legazpi, Albay.

At that time, multispectral animated satellite imagery revealed a low-level circulation center with cloud lines circling along the feature.

The system was also in an area conducive for further development, with poleward outflow, favorable wind shear, and 30 °C (86 °F) sea surface temperatures.

[6][7] Meanwhile, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) at 23:30 UTC as a circulation was now evident along the system and an organizing convective band to its south-southeast.

[8]The same agency further upgraded the storm to a tropical depression on the next day as it further consolidated, with a persistent area of thunderstorms over an obscured low level circulation center (LLCC).

[9][10] Moving northwestward under the periphery of a subtropical ridge to the northeast, its organization continued to improve with an eye feature developing and at 06:00 UTC that day, the depression strengthened to a tropical storm according to the estimates of JMA and PAGASA, with the former naming it Conson.

[11][12][13] At 09:00 UTC (17:00 PHT), the PAGASA reported that the system further intensified to a severe tropical storm while nearing Samar Island.

[18] Conson then traversed Visayas, making additional landfalls in Daram, Santo Niño, Almagro, and Tagapul-an in Samar.

[21][22] Traversing the Sibuyan Sea allowed Conson to briefly form a well-defined radar eye while maintaining strength.

[32][33] As it continued tracking westward on September 10, however, high vertical wind shear exposed its LLCC, weakening the storm.

At 21:00 UTC, the JTWC issued its final bulletin on the storm, indicating that Conson already made landfall near Da Nang and it rapidly weakened overland.

[45] The Philippine Coast Guard (PCG) suspended sea trips in the northern tip of Mindanao as early as September 6.

[50] Flights from Manila to Tacloban and Legazpi Airport (and vice versa) were cancelled on September 7 due to inclement weather.

[54] Due to Conson's approach in the country, over 500,000 soldiers were released and put on standby as its government prepared emergency plans to ride out the storm.

[60][61][62][63] Roofs of houses in Liên Chiểu District, Da Nang were secured as a precaution while boats on Thọ Quang were moved onshore.

[70] By April 4, 2022, the National Disaster Risk Reduction and Management Council in the Philippines reported 23 deaths, 32 injuries and 2 missing individuals.

[56] Rains from Conson also submerged rice fields in Libertad, Antique and destroyed a spillway in San Francisco, Quezon.

[71] Although Conson rapidly weakened before making landfall on the Vietnamese coast, the storm and its rainbands still produced heavy rainfall and winds.
