(PLO)- The North and Central regions are entering the longest heat wave so far this year. This heat wave lasts from now until May 23. The temperature can reach 39-40 degrees, some places higher.
Mr. Nguyen Van Huong, Head of Weather Forecasting Department, National Center for Hydrometeorological Forecasting, has just made a comment about the current heat wave in the North and Central Vietnam.
According to Huong, due to the impact of the western hot low pressure circulation area combined with the wind effect, from May 16 in Son La, Hoa Binh, the Northern Delta, provinces from Thanh Hoa to Quang Ngai widespread heat.
From today, May 17, this large-scale heat wave extends to the entire North, provinces from Thanh Hoa back to Phu Yen and lasts until May 23.

Particularly in the Northeast, from May 19, the heat will temporarily decrease, but only one day later, from the 20th, 21st and 22nd, the heat will return to the Northeast and expand to the whole North.
“This large-scale heat wave is the longest heat wave so far this year in the Northern region and central provinces. The common temperature is from 36-38 degrees, the western mountainous area from Thanh Hoa to Quang Ngai is affected by strong winds, the temperature can reach 39, 40 degrees. This heat wave will last until the 23rd. After the 23rd, it is likely to end” – Mr. Huong said.
Mr. Nguyen Van Huong further noted that the temperature in the meteorological tents compared to the actual temperature outside can vary from 2-4 degrees, depending on the area, if it is on a concrete or asphalt surface, the temperature will be different. may be even higher.
Mr. Mai Van Khiem, Director of the National Center for Hydro-Meteorological Forecasting, said that after 3 years of La Nina’s influence causing heavy rains and floods, ENSO is now turning neutral. The El Nino phenomenon is forecasted to appear in the second half of summer 2023 and maintain until 2024 with a probability of about 70-80%.
In El Nino conditions, in most regions of the country, the average monthly temperature tends to be higher than normal. The heat can be more and more intense. Possibility of multiple records for the absolute highest temperature.
Storm/tropical depression activity may not be much, but is more concentrated in the middle of the season, more anomalous in nature, both in intensity and trajectory. It is worth noting that El Nino often causes a rainfall deficit. Rainfall tends to decrease, but records for the heaviest rainfall in 24 hours are possible.
Data from the Electricity of Vietnam (EVN) also shows that, since the beginning of the year, hot weather, drought, and water shortage have seriously affected hydropower reservoirs.
By May 11, there were 11/47 large hydroelectric reservoirs whose water level had reached dead water level or near dead water level, including: Lai Chau, Trung Son, Dong Nai 2, Buon Tua Srah, Huong Son, Tri An, Ialy, Ba Ha River, Xekaman 1, Dakr Tih, Sesan 4.
Besides, there are 21/47 large hydropower reservoirs with the remaining capacity of less than 20%. 16 lakes have water level lower than the minimum water level of the Inter-Reservoir Operation Procedure. Meanwhile, the hot weather makes people and businesses tend to consume more electricity. The above conditions lead to the situation of power supply in the hot season will be very difficult.
Therefore, the important solution at this time, EVN proposes to the People’s Committees of provinces and centrally-run cities to pay attention to directing the use of electricity economically and efficiently, especially at peak hours of electricity use.
The Prime Minister urgently requests to cope with the risk of heat and drought
(PLO)- Prime Minister Pham Minh Chinh has just sent a telegram about proactively implementing urgent measures to cope with the risks of heat, drought, water shortage, and saltwater intrusion.
