According to forecaster Pham Phuong Chi from the National Center for Hydro-Meteorological Forecasting, this northeast monsoon is approaching Vietnam and will trigger a fresh round of stormy conditions across the northern region.

The rain is forecast to begin from the afternoon of May 7, initially appearing in scattered patches across northern provinces and the western parts of Thanh Hoa and Nghe An.

By the night of May 7, the rain band is expected to expand, covering the entire northern region and extending into north-central provinces including Thanh Hoa, Nghe An and Ha Tinh.

“The peak of this rainfall event will last from the night of May 7 through the end of May 8, with common rainfall totals ranging from 20-40mm, and some areas likely to experience heavy downpours exceeding 100mm,” Pham Phuong Chi said.

Notably, under the influence of this late-season cold air mass, temperatures across northern Vietnam on May 8 are expected to drop below 29°C, bringing cooler and more comfortable conditions.

Thunderstorms and extreme weather risks in the south

Beyond the northern developments, southern Vietnam and Lam Dong province are also forecast to experience scattered showers and thunderstorms between May 6 and 7, mainly in the late afternoon and evening. Rainfall is expected to range from 10-30mm, with some locations exceeding 60mm.

Meteorological authorities warn that as Vietnam is currently in a seasonal transition period, this round of thunderstorms is likely to be accompanied by dangerous phenomena such as tornado-like whirlwinds, lightning, hail and strong gusty winds.

Residents are strongly advised to limit outdoor activities during thunderstorms. Those already on the move should seek safe shelter immediately to protect both life and property.
