High temperatures are expected to scorch central Vietnam over the next days, raising the risk of wildfire in the region, according to the National Center for Hydro-meteorological Forecasting.
Average highs will range between 35 and 38 degrees Celsius in localities from the north-central province of Thanh Hoa to south-central Phu Yen Province.
Mercury may exceed 38 degrees Celsius in some areas.
Temperatures normally hover around 30 degrees Celsius in tropical Vietnam.
The blistering weather pattern in central Vietnam is forecast to linger in the upcoming days, posing threats to local forests as forest fires can easily break out under such conditions.
Hundreds of hectares of forest was destroyed as wildfires erupted in the north-central province of Ha Tinh three times between June 28 and July 12, with authorities having had a hard time putting out the flames due to the hot weather and strong winds.
Forest fires also occurred in Nghe An, Quang Binh, and Thua Thien-Hue on June 28 and July 1.
Temperatures between 35 and 37 degrees Celsius are in the forest in northern Vietnam, including Hanoi, on Tuesday.
Showers, however, may occur in some areas in the evening.
The UV index in the capital and the central city of Da Nang will be at a harmful level on Tuesday, as residents are advised to wear protective clothing and sunscreen when outside.
