According to the National Center for Hydro-Meteorological Forecasting, during the past 24 hours, on May 8, the Southern region experienced high temperatures ranging between 35 and 37 degrees Celsius in many areas and surpassing 37 degrees Celsius in specific locations, such as Phuoc Long (Binh Phuoc Province) at 37.2 degrees Celsius, Ta Lai (Dong Nai Province) at 37.4 degrees Celsius, Thu Dau Mot (Binh Duong Province) at 38 degrees Celsius, and Vinh Long Province at 37.4 degrees Celsius. Relative humidity was generally between 45 percent and 50 percent.
Over the next 24 to 48 hours, on May 9 and 10, the Southern region is expected to endure scorching heat, with some areas experiencing intense temperatures ranging from 34 to 37 degrees Celsius and even exceeding 37 degrees Celsius in certain places. Relative humidity levels are anticipated to range between 45 percent and 55 percent.
Localized heatwaves are expected from Quang Nam to Khanh Hoa provinces and the Central Highlands, with temperatures possibly exceeding 35 degrees Celsius in some places.
The combination of intense heat and decreased air humidity increases the risk of fires and explosions in residential areas due to heightened electricity demand and the possibility of forest fires. Moreover, the heatwave could result in dehydration, fatigue, and heatstroke due to prolonged exposure to high temperatures.
