Typhoon Yagi, known in Vietnam as Typhoon No. 3 of 2024 (Vietnamese: Bão số 3 năm 2024), originated from a tropical depression northwest of Palau, entered the South China Sea, and rapidly intensified into a super typhoon. By 7 September, Yagi made landfall in Vietnam's Haiphong City and Quảng Ninh Province, causing catastrophic damage to lives and property. The typhoon and post-typhoon severe weather brought strong winds and heavy rainfall to the entirety of northern Vietnam, triggering a series of adverse effects such as flash floods and landslides in mountainous areas. It also resulted in historic floods in northern Vietnam in early September 2024.
The Vietnamese government assessed Typhoon Yagi as the "strongest in 30 years in the South China Sea" and "the strongest in 70 years on land," noting many "unprecedented characteristics." Government reports estimate that Typhoon Yagi and the subsequent floods caused property damages of 83.7 trillion VND (approximately US$3.45 billion) and resulted in over 300 deaths and disappearances. Yagi is considered one of the most catastrophic natural disasters in Vietnamese history. [1]

Affected Provinces and Damage
According to a UN OCHA report dated September 14, 2024, 27 provinces were affected by Typhoon Yagi. These provinces were mainly located in the Northeast, Northwest, Red River Delta, and northern part of the North Central Coast region.
