The National Center for Hydro-Meteorological Forecasting updates the weather forecast for tonight and tomorrow (April 20) in regions across the country.
On the night of April 19 to April 20, the Northern region, Thanh Hoa and western Nghe An experienced scattered showers and thunderstorms, common rainfall of 15-30mm, with localized heavy rain over 70mm in some places.

Dangerous weather phenomena that may accompany thunderstorms include tornadoes, lightning, hail and strong gusts of wind. At the same time, the risk of flash floods on small rivers and streams, landslides in hilly areas and flooding in low-lying areas is present.
These weather patterns can directly affect agricultural production, causing trees to fall, damaged houses, traffic works and infrastructure.
Functional agencies recommend that people and tourists should proactively monitor weather developments, limit movement when there are heavy thunderstorms, especially in hilly areas, along rivers and streams. It is necessary to reinforce houses, reinforce signs, corrugated iron roofs; avoid sheltering under tall trees and power poles during thunderstorms and lightning to ensure safety.
