The extreme weather, which will cause temperatures to remain at above 35 degrees C for 10 to 19 hours per day, will come alongside low humidity of between 40% and 55%.
Medical experts warn of dehydration, exhaustion, and heat stroke if the human body is exposed to high temperatures for a long time.
The hot weather is set to subside from June 22 in the North, but the blistering heat in the Central region will continue for several days after.
