While Dien Bien and Son La provinces have seen rain over the past two days, most of northern Vietnam has experienced hot weather due to the influence of a hot low-pressure area to the west. Daily high temperatures have generally ranged from 35 to 37 degrees Celsius, with some areas like Hoa Binh (Phu Tho) exceeding 38 degrees Celsius.

The National Center for Hydro-Meteorological Forecasting predicts that this widespread heat, with highs of 36 to 38 degrees Celsius and some areas above 38 degrees Celsius, will persist in northern Vietnam until the end of 4/8.

From the night of 4/8 to the end of 6/8, a low-pressure trough passing through northern Vietnam will bring widespread showers and thunderstorms. The rain will be concentrated in the midlands and mountainous regions, with Lai Chau and Dien Bien potentially experiencing heavy, prolonged rain into 7/8.

As the low-pressure trough weakens from 7/8, and the western low-pressure area develops again, hot weather will return to northern Vietnam, lasting until 10/8.

Accuweather forecasts temperatures in Hanoi tomorrow between 30 and 40 degrees Celsius, decreasing to 26-32 degrees Celsius by mid-week. High-altitude areas above 1,500 meters, like Sa Pa (Lao Cai), will see mid-week temperatures around 19-21 degrees Celsius.

Central Vietnam is currently experiencing hot, dry weather due to the western low-pressure area and foehn winds. This heatwave is expected to continue throughout next week in the provinces from Thanh Hoa to Da Nang, eastern Quang Ngai to Dak Lak, and Khanh Hoa, with temperatures generally reaching 35-38 degrees Celsius and exceeding 38 degrees Celsius in some areas.

The Central Highlands and southern Vietnam will see less rainfall next week due to weaker southwest monsoon activity. High temperatures in the Central Highlands will range from 29 to 32 degrees Celsius, while southern Vietnam will see highs of 33 to 35 degrees Celsius.

The floods from the night of 31/7 to 1/8 resulted in 10 deaths in Dien Bien and four injuries in Son La. Over 100 houses were completely swept away or collapsed, and more than 200 houses were flooded or partially damaged by landslides.

Numerous roads leading to communes in the former Dien Bien Dong district of Dien Bien province were impacted by landslides, causing traffic disruptions and isolating villages. Authorities have deployed helicopters to deliver essential supplies.
