Northern Vietnam cold wave, Digi Mart USA News: Northern Vietnam is expected to experience the first widespread cold wave of the winter season next week, following the passage of a strong cold front, with temperatures dropping below 13°C in some areas while central Vietnam is hit by heavy rain.
According to the National Center for Hydro-Meteorological Forecasting, a strong cold front is moving south across the north. Scattered showers and thunderstorms are forecast in the north, with afternoon temperatures generally between 29 and 32°C.
In the late afternoon and evening of November 8, the cold air mass will affect the northeastern region, followed by the northwestern region, the north-central and central-coastal regions, and parts of the south-central region. Inland, winds will shift to the northeast at force 3–4, reaching force 5 in coastal areas and force 6 in some locations, with gusts up to force 7.
From the night of November 8, mountainous areas of northern Vietnam will be hit by the cold wave, with some high-altitude areas recording particularly low values. Other parts of northern and north-central Vietnam will feel the cold starting November 9.
During this cold wave, minimum temperatures in northern and north-central Vietnam are generally expected to range between 16 and 19°C, while some mountainous areas are forecast to fall below 13°C.
In Hanoi, the cold air mass began affecting the area on the evening and night of November 8. From that evening until the morning of November 9, rain and showers fell, with heavy rain and thunderstorms in some areas.

During thunderstorms, there is a high probability of tornadoes, lightning, hail and strong gusts of wind. Such storms can affect agricultural production, bring down trees, and damage houses, transport infrastructure and other structures.
Heavy rain may cause flash floods on small rivers and streams, landslides on slopes, and flooding in lowland areas.
