The Northern region (except Lai Chau, Dien Bien) and North Central region from the night of April 16 to April 17, due to the influence of cold air compressing low pressure troughs combined with wind convergence above 1500m, it is forecast to have rain, moderate rain and scattered thunderstorms with rainfall from 20 - 40mm, locally very heavy rain over 100mm. From April 17, the North will turn cool.

Localized heavy rains are likely to cause flash floods on small rivers and streams, landslides on slopes, and flooding in low-lying areas. Disaster risk level warning due to tornadoes, lightning, and hail is level 1.
