On October 20th, Dr. Hoang Phuc Lam, Deputy Director of the National Center for Meteorological and Hydrological Forecasting, stated that strong northeast monsoon winds had swept in, weakening and dissipating Typhoon No. 5 while it was still at sea, causing the North to become colder, with mountainous areas experiencing freezing temperatures at night and early morning.

On October 20th, a cold front will affect the northeastern region of Vietnam, then the North Central region and some areas in the northwestern region. Northeast winds inland will be strong at level 2-3; coastal areas from Quang Ninh to Hai Phong will experience strong winds at level 6, gusting to level 7-8, due to the combined influence of the cold front and the circulation of typhoon No. 5.

From the night of October 20th to 22nd, the weather in Hanoi , the Northern region, and the North Central region will be cold at night and in the morning, while the northern mountainous areas will experience freezing temperatures at night and in the early morning.

During this cold spell, the lowest temperatures in Northern Vietnam and North Central Vietnam will generally range from 19-22 degrees Celsius, while in the mountainous areas of Northern Vietnam they will commonly be between 16-19 degrees Celsius, and in some high mountainous areas, temperatures may drop below 14 degrees Celsius.

Specifically for Hanoi, according to Dr. Lam, from October 20-22, there will be insignificant rainfall, mostly cloudy skies and colder temperatures, accompanied by northeasterly winds of level 2-3; the highest temperature will be 25-27 degrees, and the lowest temperature will be 21-23 degrees.

From October 23rd, temperatures will rise rapidly to 28-32 degrees Celsius during the day and 23-26 degrees Celsius at night; the weather throughout the following period will also be mostly dry and sunny.

Meanwhile, in Central Vietnam, the weather turned sunny after several consecutive days of heavy rain. However, from October 21st, the northern and central parts of Central Vietnam will experience scattered showers and thunderstorms, with localized moderate to heavy rain. From October 22nd to 24th, this area is likely to have moderate to heavy rain, with some places experiencing very heavy rain and scattered thunderstorms.

The Central Highlands and Southern regions will continue to experience the rainy season weather pattern, with sunny days interspersed with clouds, and scattered showers and thunderstorms in the late afternoon and evening.

Here are the specific weather forecasts for Hanoi over the next three days (October 20-22) :

Typhoon No. 5 is likely to dissipate quickly over the sea due to 'contact' with cold air.

After entering the Gulf of Tonkin, Typhoon No. 5 will encounter cold air and weaken rapidly before dissipating over the sea. However, this "collision" of weather patterns has the potential to cause strong and dangerous thunderstorms in the sea area.

Hanoi weather forecast for the next 3 days: Cold air mass arrives, temperature drops by 5 degrees.

Hanoi's weather forecast for the next three days (October 19-21) predicts generally no rain or light rain in the early morning. On the weekend (October 21), as the cold air mass moves in, the temperature will drop by 5 degrees.
