Northern parts of the Indochina Peninsula are experiencing severe wind and rain

Typhoon Wipha (The 6th typhoon of this year) made its second landfall along the coast of Thai Binh Province, Vietnam, around 9:30 AM (BJT, hereafter) today (July 22). After making landfall, it weakened to a tropical storm, with maximum sustained winds near the center reaching 9 levels (23 meters per second) and the minimum central pressure at 980 hPa. Affected by the typhoon, on July 21, northern Vietnam experienced heavy to torrential rain, with localized extremely heavy downpours (Figure 2).

Typhoon Wipha is expected to weaken into a tropical depression around 5:00 PM on the July 22. Under the influence of its residual circulation, heavy to torrential rains will occur successively in the northern and western parts of the Indo-China Peninsula, Bangladesh, and central and northern India over the next three days (July 22-24). Some areas will experience extremely heavy rainfall, accompanied by severe convective weather such as short-duration intense rain and thunderstorms with strong winds. The cumulative precipitation in most of these regions is expected to be between 70 and 100 mm, with some areas receiving 120 to 180 mm, and locally exceeding 200 mm (Figure 3). Additionally, north-central Vietnam and eastern Laos will experience strong winds of 6 to 7 on the Beaufort scale, with gusts reaching 9 to 10. Attention should be given to the adverse impacts of the severe wind and rain on power facilities, transportation, and other sectors in the affected areas, as well as the potential for heavy rainfall to trigger secondary disasters such as flooding, landslides, mudslides, and urban waterlogging.
