Thunderstorms expected from the evening of June 25 are set to bring an end to several days of extreme heat in the north, according to the National Centre for Hydro-Meteorological Forecasting. Central Vietnam, however, will remain under severe hot weather conditions.
From this evening and overnight, mountainous and midland areas in the north are forecast to experience heavy to very heavy rain, with rainfall of 20-40 mm, and in some places exceeding 130 mm. The Red River Delta, including Hanoi, is expected to see scattered showers and thunderstorms, with rainfall of 10-30 mm and localised areas exceeding 70 mm.
The thunderstorms are being formed by a strengthening trough combined with upper-level wind convergence. From June 26, the heatwave in northern Vietnam is expected to end, with daytime temperatures ranging between 31-34 degrees Celsius.
According to AccuWeather, Hanoi’s temperature on June 26 will drop by around seven degrees Celsius compared to the previous day, falling to 26-32 degrees Celsius. In Sapa (Lao Cai Province), temperatures are forecast to decrease to 19-21 degrees Celsius.
Meanwhile, areas from Thanh Hoa to Danang and the eastern parts of Quang Ngai to Dak Lak will continue to experience intense heat. On June 26-27, peak temperatures are expected to range from 36-38 degrees Celsius. In particular, regions from Nghe An to Danang and eastern Quang Ngai may reach 37-39 degrees Celsius, with some places exceeding 39 degrees Celsius. The heatwave in central Vietnam is forecast to persist for several more days.
Meteorological authorities warn that thunderstorms in northern Vietnam, the Central Highlands and southern regions may be accompanied by tornadoes, lightning, hail and strong gusts of wind. Localised heavy rainfall may also increase the risk of flooding in low-lying urban areas, as well as flash floods and landslides in mountainous regions.
Forecast temperatures are measured under standard conditions. In reality, outdoor temperatures, especially in areas with dense concrete, asphalt and limited greenery, may feel two to four degrees Celsius higher.
