In recent days, the midlands and mountainous areas of the North have had scattered showers and thunderstorms, with some places experiencing heavy rain. Meanwhile, the main weather in the Northern Delta is dry and sunny. The highest temperature during the day is around 29 - 32 degrees Celsius.
According to the National Center for Hydro-Meteorological Forecasting, from October 19 to October 22, the North is likely to have scattered showers and thunderstorms in some places due to the impact of a cold air mass.
However, due to the weak cold air intensity, the temperature decrease is not significant. Temperatures in the Northern Delta generally fluctuate from 24 - 31 degrees Celsius.
From the night of October 22, the nights and mornings will be cold, with temperatures dropping by about 2-3 degrees Celsius compared to previous days. From October 23, the weather will be mostly sunny during the day.
"The cold air that appears at this time will almost certainly cause rain because of the conflict between the warm and cold air masses. The rain will be relatively heavy and may be accompanied by thunderstorms and strong gusts of wind.
"Then, when the cold air moves deeper, the weather quickly turns dry," said Mr. Nguyen Duc Hoa, Deputy Head of Climate Forecasting Division, National Center for Hydro-Meteorological Forecasting.
The North Central region is also likely to be affected by this cold air mass. From the night of October 19 to 22, the North Central region will have scattered showers and thunderstorms, with some places experiencing heavy rain.
