Currently, a weak cold air mass is compressing a low pressure trough, moving from the North to overflow into the North. Forecast from the night of April 16 to April 17, the weather in the North (except Lai Chau, Dien Bien) and Thanh Hoa will have moderate rain, with heavy rain in some places, accompanied by tornadoes, lightning, hail and strong gusts of wind.
