Warning level of natural disaster risk due to hot weather is level 1.
Due to the influence of hot weather combined with reduced humidity in the air, there is a high risk of fires and explosions in residential areas due to increased electricity demand. In addition, hot weather can also cause dehydration for the human body when exposed to high temperatures for a long time.
Note that the forecast temperature in hot weather bulletins and the actual perceived temperature outside can differ from 1 - 3 degrees Celsius, or even higher depending on the condition of the buffer surface such as concrete and asphalt roads.
