Description Despite the weakening of Typhoon Maysak, its circulation, combined with prevailing weather conditions, has continued to bring heavy rainfall across northern Viet Nam, particularly affecting the mountainous provinces of Dien Bien, Lao Cai and Thai Nguyen. Continued rainfall has maintained the risk of flash floods, landslides and localised flooding, causing damage to housing, agriculture and critical infrastructure while disrupting transportation and local livelihoods. Authorities remain on high alert as additional rainfall is forecast over the coming days. According to rapid reports from the Provincial Departments of Agriculture and Environment of Lai Chau, Dien Bien, Lao Cai, Son La, Tuyen Quang, and Thai Nguyen, heavy rainfall and landslides between the afternoon of 8 July and 9 July caused widespread damage to housing, agriculture and infrastructure. One person was injured in Son La Province after falling rocks struck a vehicle. Four houses were destroyed, 141 houses were damaged, 36 additional houses were affected by flooding and landslides, and 45 households were evacuated due to landslide risks. Agricultural losses continued to increase, with approximately 243 hectares of rice fields, crops and other cultivated land flooded or damaged across six provinces. Floodwaters also killed or swept away 24 head of livestock and 350 poultry, primarily in Dien Bien and Thai Nguyen provinces. Transportation infrastructure was significantly affected as landslides and flooding disrupted traffic at 17 locations along National Highways 6, 4H, 12, and 32, as well as at 75 locations on provincial roads across Lai Chau, Dien Bien, Lao Cai, and Son La provinces. Damage was also reported to irrigation infrastructure, with 137 metres of irrigation canals damaged in Dien Bien and Tuyen Quang provinces.
