Warning level of natural disaster risk due to hot weather is level 1. Due to the impact of hot and intense heat combined with low humidity in the air, there is a risk of fire and explosion in residential areas due to increased electricity demand and the risk of forest fires. 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 2 - 4 degrees Celsius, and may even be higher depending on the condition of the buffer surface such as concrete and asphalt roads.
