In recent days, Northern Vietnam has been under the influence of a western low-pressure heat system, driving temperatures to 37–39°C. Some areas, including Hanoi, recorded highs of 40–41°C.

While heat continues in the Northern Delta on August 5, it is expected to ease slightly, with temperatures ranging from 35–36°C in most places, ahead of an incoming cooling rain.

Early on August 5, some northern mountainous and midland areas already saw heavy rainfall and thunderstorms. The region is expected to remain mostly cloudy with scattered showers, leading into widespread heavy rain from the evening of August 5 through August 7.

From the afternoon of August 5 through the morning of August 7, total rainfall in the mountainous and midland areas is forecast to reach 60–120mm, with isolated locations possibly exceeding 250mm.

After enduring days of extreme heat, northern provinces should be on alert for severe weather conditions including lightning, whirlwinds, hail, and strong gusts. Torrential rain may lead to flooding in low-lying urban areas, flash floods in small rivers and streams, and landslides on steep terrain.

Meanwhile, from August 5–6, central provinces from Thanh Hoa to Da Nang, as well as the eastern areas of Quang Ngai to Dak Lak and Khanh Hoa, will continue to face hot to extremely hot conditions. Daytime temperatures are expected to range from 36–38°C, with some places exceeding 38°C. Relative humidity will drop to 50–55%. This heatwave is likely to persist in the coming days.

Authorities also caution that the perceived outdoor temperature may feel 2–4°C higher than forecasted, especially in areas with heat-retaining surfaces like asphalt and concrete.
