Part of the 2022 Pacific typhoon season

Tropical Storm Sonca (transliterated from Vietnamese Sơn Ca), was a weak but damaging tropical storm that impacted Vietnam in mid-October 2022. The thirtieth tropical depression, and nineteenth tropical storm of the 2022 Pacific typhoon season, Sonca developed from a scattered area of convection within a broad low-level center. As it became slightly organized, the Japan Meteorological Agency (JMA) classified the system as a depression on October 13, while the Joint Typhoon Warning Center (JTWC) followed suit the next day, naming the system 22W. Not long after, the system intensified into a tropical storm, receiving the name Sonca by the JMA. It soon made landfall on Da Nang, Vietnam. Sonca rapidly weakened over land, and the JTWC and JMA both issued their final advisories on Sonca.

Sonca, despite being weak caused heavy damage throughout central Vietnam, bringing 700 mm (28 in) of rainfall resulting in major flooding. Overall, Sonca was blamed for 12 fatalities, and damages inflicted costed 2.4 trillion VND (US$101.5 million.)
