According to the National Center for Hydrometeorological Forecasting, rain will ease, and temperatures will begin to rise from September 12-13, bringing a much-needed break in the weather.

From September 10-11, Northern Vietnam will experience heavy rain, with some areas receiving very heavy rainfall and thunderstorms. Starting from September 12, rain will decrease, with scattered showers and occasional thunderstorms expected until September 19.

Central Vietnam will also experience sunny weather today (September 10), with scattered rain and thunderstorms in the evening and night. Particularly in Nghe An and Ha Tinh, moderate to heavy rain is expected. From September 11-19, the region will experience mostly sunny days, with isolated rain and thunderstorms in the evenings.

In the Central Highlands and Southern Vietnam, scattered showers and thunderstorms are forecast, with localized heavy rain expected during the afternoons and evenings.

On September 10, northern mountainous and midland regions, including Lao Cai and Yen Bai, are predicted to receive 40-80mm of rain, with some areas seeing over 150mm. Rainfall levels will remain high on September 11, with 30-60mm of rain expected, and some areas could see over 120mm.

The Red River Delta, along with Hoa Binh, Thanh Hoa, and Nghe An, will also face heavy rain through the night of September 10, with rainfall between 50-120mm and some areas exceeding 300mm. Rain will continue into September 11 with similar intensity.

Meanwhile, Hanoi will see moderate to heavy rain through September 12, with scattered thunderstorms. From September 13-19, occasional showers and thunderstorms are expected, particularly in the evenings, while the days will see reduced cloud cover and sunshine. Daytime temperatures are forecast to rise to 31-33°C, with nighttime lows of 23-26°C.

The meteorological agency has warned of potential flash floods, landslides, and strong winds during thunderstorms, which could lead to flooding in low-lying areas. Rivers across Northern Vietnam are swelling, with the water levels of several major rivers surpassing historical highs.

At 7am on September 10, water levels on the Thao River in Yen Bai had reached 35.32 meters, surpassing the historical flood level from 1968 by 1.1 meters. Water levels on the Cau River at Dap Cau were recorded at 6.12 meters, and on the Thuong River at Phu Lang Thuong, levels reached 6.65 meters, both near the third-level flood warning.

In the next 12-24 hours, water levels are expected to continue rising in several rivers, including the Red River in Hanoi, where floodwaters are predicted to reach the second warning level.

On the night of September 9, Hanoi’s Mayor Tran Sy Thanh issued an urgent directive instructing city authorities to prepare for large-scale floods on major rivers, prioritizing flood response measures to protect residents and infrastructure.

As Northern Vietnam continues to face heavy rain and potential flooding, authorities urge residents in flood-prone areas to remain vigilant and follow evacuation orders where necessary.
