Typhoon Wipha will affect Vietnam, Myanmar, and Other Regions

 

Affected by Typhoon Wipha (No. 6) (Figure 1), it is expected that from July 21 to 24, heavy to torrential rain will occur successively in central and northern Vietnam, Laos, central and northern Thailand, Myanmar, Bangladesh, and eastern India. Some areas will experience extremely heavy rain, accompanied by severe convective weather such as short-duration intense rainfall and thunderstorms with strong winds. The cumulative precipitation in most of these regions will range from 70 to 140 mm, with some areas receiving 150 to 200 mm. Notably, localized areas in Vietnam's Ninh Bình, Thanh Hóa, and Ngh? An provinces, Laos' Xiengkhouang and Borikhamxay provinces, Thailand's Sayaboury Province, Myanmar's Karen State, and Tanintharyi Region are expected to exceed 300 mm (Figure 2). Additionally, central and northeastern Vietnam, and eastern Laos will experience strong winds of 68 gales ,with gusts reaching 911 (Figure 3).

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.
