Due to the influence of hot weather combined with reduced humidity in the air and southwest winds causing a flat surface effect, there is a risk of fire and explosion in residential areas due to increased demand for electricity and the risk of forest fires.
Hot weather can also cause dehydration, exhaustion, and heat stroke in the human body when exposed to high temperatures for a long time.
Note, the forecast temperature in hot weather reports and the actual outdoor temperature may vary by about 2 - 4 degrees Celsius, or even higher depending on buffer conditions such as concrete and asphalt.

The National Center for Hydro-Meteorological Forecasting predicts that from the night of June 8 to 10, the North will have scattered showers and thunderstorms, with some places having heavy rain. The rain will be concentrated in the late afternoon and night.
Regarding the trend of temperature in June, the average heat platform across the country is approximately approximately the average for many years; Particularly, the Northern region is 0.5 - 1 degrees Celsius higher than the average of the same period.
Hot weather is likely to appear widely in the first days of June 2025 and may continue to occur in some months in the North and Central regions.
The meteorological agency warns that it is necessary to be on guard against the possibility of severe and especially severe heat in the above areas.
The increased heat waves pose a very high risk of fire and explosion in the Northern and Central regions.
