Level 1 risk of natural disasters due to flash floods, landslides, and land subsidence caused by heavy rain or runoff.

Flash floods and landslides can have very serious impacts on the environment, threatening people's lives; causing localized traffic congestion, affecting the movement of vehicles; destroying public and economic infrastructure, causing damage to production and socio-economic activities.

The meteorological and hydrological agency recommends that local authorities pay attention to reviewing bottlenecks and vulnerable locations in the area to take preventive and response measures.

According to the National Center for Hydro-Meteorological Forecasting, on the evening and night of May 21st, other areas of Northern Vietnam will experience scattered showers and thunderstorms with rainfall amounts of 10-30mm, and locally heavy rain exceeding 60mm.

The Central Highlands and the southeastern region of Vietnam will experience scattered showers and thunderstorms with rainfall amounts of 10-20mm, and locally heavy rain exceeding 50mm in some areas.  

Thunderstorms accompanied by tornadoes, lightning, hail, and strong gusts of wind can affect agricultural production, cause trees to fall, damage houses, transportation infrastructure, and other facilities. Localized heavy rainfall can cause flash floods on small rivers and streams, landslides on slopes, and flooding in low-lying areas.
