The National Center for Hydro-Meteorological Forecasting announced that the northern region, excluding Lai Chau and Dien Bien, will experience thunderstorms from the night of 16/4 until the end of 17/4. Rainfall is expected to be 20-40 mm, with some localized areas receiving over 100 mm.

These thunderstorms could bring tornadoes, lightning, hail, and strong gusts, risking uprooted trees and damage to homes, transportation infrastructure, and other facilities. Local heavy rainfall may also trigger flash floods in small rivers and streams, landslides in hilly areas, and inundation in low-lying regions.
