Typhoon Kajiki will affect Central and Northern Vietnam

Affected by Typhoon Kajiki (No. 13) (Figure 1), heavy to very heavy rainfall is expected in central and northern Vietnam from August 24 to 25. Specifically, localized downpours or intense rain are anticipated in the provinces of Yen Bai, Phu Tho, Hoa Binh, Ha Tay, Ha Nam, Thai Binh, Nam Dinh, Ninh Binh, Thanh Hoa, Nghe An, Ha Tinh, Quang Binh, and Quang Tri. Accumulated precipitation in most of these areas is forecasted to be between 50 and 90 mm, with some regions receiving 100 to 180 mm, and isolated areas exceeding 280 mm (Figure 2). Coastal areas in central and northern Vietnam will experience strong winds of 7-8 gales, with gusts reaching 9-10 (Figure 3). Additionally, heavy to very heavy rain is also expected in Laos and northern Thailand, with localized intense downpours in central Laos.

Attention should be given to the adverse impacts of strong winds and heavy rain on power facilities, transportation, and other industries in the aforementioned regions. Additionally, there is a risk of secondary disasters such as flooding, landslides, mudslides, and urban waterlogging that may be triggered by the intense rainfall.
