According to the National Center for Hydro-Meteorological Forecasting, currently (April 14), in the North, there is a weak cold air mass moving southward, compressing a low pressure trough with its axis at about 24 - 27 degrees north latitude.
Forecast 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, in the Northern region (except Lai Chau, Dien Bien) and Thanh Hoa there will be rain, moderate rain and scattered thunderstorms with rainfall from 20 - 40mm, locally heavy rain over 100mm. In thunderstorms, there is a possibility of tornadoes, lightning, hail and strong gusts of wind. From April 17, the North will turn cool.
Thunderstorms occurring after a prolonged heat wave can cause extreme phenomena. The meteorological agency warns that thunderstorms accompanied by tornadoes, lightning, hail and strong gusts of wind can affect agricultural production, causing trees to fall, damage to houses, traffic works, and infrastructure.
Localized heavy rain is likely to cause flash floods on small rivers and streams, landslides on slopes and flooding in low-lying areas. Warning level of natural disaster risk due to tornadoes, lightning, and hail is level 1.
