Warning level of natural disaster risk due to hot weather is level 1. Due to the impact of hot weather combined with low humidity in the air, there is a risk of fire and explosion 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 2 - 4 degrees Celsius, or even higher depending on the condition of the buffer surface such as concrete and asphalt roads.
The National Center for Hydro-Meteorological Forecasting added that it is forecast that from the night of March 31st to April 1st, the North may be affected by a weak cold air wave. Therefore, in the period from April 1st to April 2nd, the weather will be cool, and the mountainous areas will be chilly.
Warning, due to this weather change, there will be a conflict between weak cold air and hot air mass, causing the mountainous areas of the Northern and North Central regions to be likely to experience strong thunderstorms, accompanied by the risk of tornadoes, lightning, hail and strong gusts of wind.
These phenomena often occur quickly and unexpectedly, can cause roofs to be blown off, trees to fall, and affect people's lives, production, and lives.
The meteorological agency recommends that people closely monitor weather forecasts, limit going out when there are thunderstorms, and proactively reinforce houses, protect property and vehicles to minimize damage.
