Prolonged rainfall may increase the risk of urban flooding and landslides in mountainous areas.
Speaking with reporters, Mai Van Khiem, Director of the National Centre for Hydro-Meteorological Forecasting said, “From now until the end of 2025, about two to three storms or tropical depressions are likely to form over the East Sea, with one or two possibly affecting Vietnam.”
According to Khiem, moderate to heavy rains will likely persist in central Vietnam through mid-December 2025, concentrating mainly in areas from Ha Tinh to Danang, Khanh Hoa, and the eastern parts of Quang Ngai to Dak Lak.
Forecasts show that in November 2025, total rainfall across most regions nationwide will be 10-30 per cent higher than the long-term average, with some areas expected to see even greater increases. In contrast, the northern mountainous region may record 10-20 per cent less rainfall than the average, while the northern delta will remain close to normal levels.
In December 2025, rainfall in provinces from Quang Tri to Danang and the eastern areas from Quang Ngai to Dak Lak is expected to range between 250-580 mm, 50-150 mm above the long-term average.
In the north and from Thanh Hoa to Ha Tinh, rainfall will generally range 15-40 mm, while Ha Tinh itself may reach 80-150 mm, about 5-10 mm below average.
Other regions are forecast to record 40-80 mm, 10-40 mm above the long-term average for the same period.
