According to the National Center for Hydro-Meteorological Forecasting, yesterday, April 19, in the Northwest, the area from Thanh Hoa to Phu Yen had hot and extremely hot weather with the highest temperature commonly ranging from 35-37 degrees Celsius, in some places above 37 degrees Celsius.
The area from Nghe An to Quang Ngai has intense heat, some places have especially intense heat with the highest temperature commonly 37-39 degrees Celsius, some places over 40 degrees such as Muong La (Son La) 42.4 degrees Celsius
Dien Bien , Son La and the area from Nghe An to Quang Ngai have severe heat, some places have especially severe heat with the highest temperature commonly 37-39 degrees Celsius, some places have over 40 degrees such as Muong La (Son La) 42.4 degrees Celsius, Song Ma and Yen Chau (Son La) 41.3 degrees Celsius, Tuong Duong (Nghe An) 40.3 degrees Celsius, Nam Dong (Thua Thien - Hue) 40.7 degrees Celsius... The lowest relative humidity is commonly 20-55%.
It is forecasted that in the Northwest and the area from Thanh Hoa to Phu Yen, there will be hot and extremely hot weather, with some places being especially extremely hot with the highest temperature commonly ranging from 36-39 degrees Celsius, and some places above 40 degrees Celsius. The lowest relative humidity is commonly 20-55%. The Northeast will have hot weather from April 21.
Warning of severe heat, especially severe in some places in the Northwest, the area from Thanh Hoa to Phu Yen is likely to last until around April 23, from April 24 the heat will gradually ease. In the Northeast on April 22 there will be widespread heat, from April 23 the heat will gradually decrease.
Due to the effects of heat and intense heat combined with low humidity and the southwest wind causing the foehn effect, there is a risk of explosions and fires in residential areas due to increased demand for electricity and the risk of forest fires. In addition, heat can also cause dehydration, exhaustion, and heat stroke to the human body when exposed to high temperatures for a long time.
Mr. Hoang Phuc Lam, Deputy Director of the National Center for Hydro-Meteorological Forecasting, said that in 2023, the ENSO phenomenon (irregular cyclical changes in wind and sea surface temperature in the Eastern Pacific Ocean) will remain neutral from now until about June 2023. After that, the sea surface temperature in the central Pacific Ocean will tend to increase gradually and lean towards the El Nino warm phase.
It is forecasted that from April to June 2023, the temperature across the country will be approximately equal to or about 1 degree Celsius hotter than the average of many years. Each heat wave usually lasts 3-5 days, this year it may be longer, about 5-7 days, especially in the Central region, more than 7 days. The peak of summer will be June-July in the North and from late June to August in the Central region with the possibility of severe heat (from 37 to 39 degrees Celsius) and especially severe heat (from 39 degrees Celsius and above). It is forecasted that the heat wave will end in the South from June, the North will last until early August, and the Central region until the end of August.
