HÀ NỘI — The National Center for Hydro-Meteorological Forecasting predicts that there will be widespread hot and intense heat across the country for at least two more days, until April 30. After that, the heat is expected to gradually ease starting from May 1.

This prolonged heatwave poses an increased risk of natural disasters, especially at level 1, with specific regions like Sơn La, Hòa Bình, and from Thanh Hóa to Phú Yên facing a level 2 risk.

On April 28 and 29, the provinces of Sơn La, Hòa Bình, and Thanh Hóa to Phú Yên will experience exceptionally intense heat. Temperatures are expected to commonly reach 39-42 degrees Celsius, and in some areas, exceed 42 degrees Celsius. Relative humidity levels are forecasted to range from 30-35 percent.

Likewise, the northern, central highlands, and southern regions will experience scorching and intense weather, with temperatures ranging from 36-39 degrees Celsius, occasionally exceeding 39 degrees Celsius. The humidity is expected to be between 40-45 per cent.

From Khánh Hòa to Bình Thuận provinces, hot weather is expected to range from 35-37 degrees Celsius, with some areas exceeding 37 degrees Celsius. Humidity typically ranges from 45-50 per cent.

Meteorological experts are warning about the potential hazards that can arise from intense heat and low humidity. These hazards include an elevated risk of explosions and fires in residential areas due to increased electricity usage, as well as an increased likelihood of forest fires.

Prolonged exposure to high temperatures can lead to dehydration, exhaustion, and heat strokes.

It's important to note that forecasted temperatures may differ from actual outdoor conditions by 2-4 degrees Celsius or more, depending on surface materials such as concrete or asphalt.
