A new cold front is set to descend on Northern Vietnam starting October 27, bringing lower temperatures, scattered rain showers, and thunderstorms, particularly affecting the Red River Delta and northern coastal areas.

Mountainous regions could see temperatures drop as low as 14°C, according to the National Center for Hydro-Meteorological Forecasting.

This cold air mass is expected to bring cooler weather throughout the North and parts of Central Vietnam, with heavy rains predicted along the coast, influenced by Typhoon Trami (Typhoon No. 6).

From October 26, daytime highs in Hanoi will reach 30-32°C but will fall to around 25-26°C as the cold front takes effect, while early mornings are expected to drop to around 20°C, creating cool, crisp air with higher humidity.

Coastal cities, including Quang Ninh, Hai Phong, and Nam Dinh, could experience cool temperatures throughout the day, and mountain areas near the northern border, such as Lang Son, may see temperatures ranging from 25°C to as low as 14°C by October 28.

Meteorologists expect these conditions to persist for two days, after which weather in Northern Vietnam may clear up with drier air and sunny, warm days. Another cold front is anticipated in early November, which could bring further cool weather.

As Typhoon No. 6 nears the coast, provinces from Quang Tri to Binh Dinh have already experienced rain showers and thunderstorms.

Heavy rains are forecasted from October 26 to 28, with rainfall expected to reach 200-450mm and possibly exceeding 600mm in some areas. Heavy rain could also affect the northern Central Highlands, with some areas experiencing up to 300mm of rainfall.

The Central Highlands and Southern Vietnam, particularly on the evening of October 27, are expected to see scattered rain showers, with heavier rains anticipated between October 29 and 31.

The prolonged rain and localized downpours may lead to urban flooding in low-lying areas, flash floods along rivers, and landslides on steep slopes.
