The meteorological agency warns of the risk of natural disasters due to heat at level 1. Due to the influence of hot weather, some places are experiencing severe heat combined with low humidity in the air, so there is a high 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.
The National Center for Hydro-Meteorological Forecasting noted that the forecast temperature in hot weather reports and the actual outdoor temperature may vary by 2 - 4 degrees Celsius, or even higher depending on buffer conditions such as concrete and asphalt roads.
Previously, according to the Head of the Weather Forecast Department, the North experienced a record heat wave in August. From August 2 to 4, hot and severe heat will occur widely in the Northern and Central regions. This heat wave has the highest temperature in the Northern region, concentrated in the midlands and deltas of the North with the peak of the heat wave on August 3 and 4.
The highest temperature is generally from 38 - 40 degrees Celsius, some places above 40 degrees Celsius such as Lang (Hanoi) are 40.3 degrees Celsius, Phu Ly (Ninh Binh) is 40.2 degrees Celsius (while in the Central region, the highest temperature is only generally from 36-38 degrees Celsius, some places are approximately 39 degrees Celsius).
"According to statistics in the Northern region, there have been 20 meteorological stations that have recorded the highest temperature values of the day exceeding the previous historical values recorded in the same period in August" - Mr. Huong provided information.
According to Mr. Huong, although the temperature value recorded during this hot period is not the highest level ever recorded in the summer in the North (usually occurring in June or July), however, compared to the same period in August in previous years, this is still a rare temperature.
