The heatwave is due to the southern edge of a low-pressure trough connecting with a hot low-pressure zone from the westward.

From tomorrow, the soaring temperature of up to 38 degrees Celsius and humidity of 45-60 percent are likely to hit the Northern region and provinces from Thanh Hoa to Phu Yen on the large scale from 12 a.m. to 5 p.m. Amidst the warnings above, local people need to raise awareness for forest fire risk under the prolonged heatwave.

The heatwave is forecast to last until the beginning of June.
