Typhoon "Kajiki" Impacts Northern Laos and Northern Thailand

Typhoon Kajiki, the 13th typhoon of this year, made landfall near the northern coast of Ha Tinh Province, Vietnam, around 19:10 on the evening of the 25th (Beijing time, same as below). At the time of landfall, the maximum wind speed near the center was 13 levels (38 m/s). Observations indicate that parts of central Vietnam, central Laos, northern Thailand, and Myanmar have experienced rainfall of 100-250 mm in the past 24 hours, with localized areas exceeding 250 mm (Figure 1).

At 10:00 AM on the 26th, the center of Typhoon "Kajiki" is located within the Xiangkhouang Province of Laos (Figure 2). It is expected to move northwestward at a speed of approximately 25 kilometers per hour, with its intensity continuing to weaken (Figure 3). From August 26 to 27, affected by Typhoon "Kajiki" and its remnants (Figure 4), heavy to very heavy rainfall is anticipated in parts of central and northern Vietnam, northern Laos, northern Thailand, and central and eastern Myanmar. Most of these areas are expected to receive cumulative rainfall of 60-100 mm, with some regions experiencing 120-160 mm, and localized areas exceeding 200 mm (approaching or surpassing historical extreme values for the same period).

Attention should be given to the adverse impacts of strong winds and heavy rain on power infrastructure, transportation, and other sectors 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.
