The average temperature in most regions across the country is generally about 0.5 degrees Celsius lower than the average of many years; in particular, the provinces from Nghe An to Hue are generally 0.5-1 degrees Celsius lower than the average of many years in the same period.

"During this period, cold air continues to increase in frequency and intensity. Across the country, there is a continued possibility of dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind," Ms. Tran Thi Chuc noted.

Deputy Head of the Department Tran Thi Chuc warned that storms, tropical depressions and cold air cause strong winds, large waves at sea and affect the activities of ships. In particular, beware of heavy rains that can cause floods, inundation in low-lying areas and landslides in mountainous areas. Heavy rains, thunderstorms, whirlwinds and lightning can negatively affect traffic activities, production and public health.

In the context of climate change, weather and climate are becoming more and more complex with many dangerous and extreme forms such as heavy rain in a short time, flash floods, landslides, etc. Therefore, it is recommended that authorities at all levels and people regularly update and integrate meteorological and hydrological forecast and warning information in short-term bulletins of 1-3 days, to promptly adjust production plans, appropriate response plans, especially appropriate reservoir operation plans, ensuring safety of works and downstream areas, along with ensuring safety for production activities and people's lives.
