Northern Vietnam to experience thunderstorms before heatwave

Hanoi and the provinces of Son La and Hoa Binh experienced rain and thunderstorms accompanied by hail on Saturday night.

This was due to the southern edge of a low-pressure trough with an axis at 23-25 degrees latitude connected to a low-pressure area in the west being compressed by a cool air mass moving down fromChina.

On Sunday morning, the National Center for Hydro-Meteorological Forecasting stated that the low-pressure trough with an axis at 23-25 degrees latitude will continue to be pushed down by the cool air mass in the next few days. Therefore, the northern provinces will maintain thunderstorm conditions, tornadoes, lightning, and hail in the afternoons and evenings.

From April 25, the low-pressure area in the west is likely to develop again, while the cool air mass in the north will no longer be present. The temperature in the north will gradually increase, and there is a possibility of widespread hot weather.

According to American site Accuweather, Hanoi's temperature from now until Wednesday will reach a maximum of 31 degrees Celsius during the day and 25 degrees at night.

From Thursday, the temperature will gradually increase to 36-38 degrees, 27 degrees at night. Areas located over 1,500 m above sea level such as Sa Pa will have temperatures next week ranging 17-27 degrees.

Elsewhere, the Central region has been experiencing widespread heat since April 19. Meteorological agencies predict that in the next three days, the heatwave area will gradually narrow as the hot low-pressure area in the west weakens.

The hot zone is concentrated in the area from Ha Tinh to Quang Ngai provinces, and Binh Dinh to Phu Yen, with the highest daytime temperatures commonly 35-38 degrees.

From April 25, as the hot low-pressure area develops again, the heatwave will expand to from Thanh Hoa to Nghe An.

Southern Vietnam and the Central Highlands will still experience widespread heat next week.

In the south, intense sunshine with temperatures reaching 35-38 degrees will continue. The southeastern region, home to HCMC, Dong Nai and Binh Duong, might experience temperature of above 38 degrees.

In the Central Highlands, temperatures are commonly between 34-37 degrees, some places above 37 degrees. However, in the afternoon and evening, the region, home to Lam Dong, Dak Nong and Dak Lak, may experience localized thunderstorms accompanied by tornadoes, lightning, hail, and strong gusts.
