According to the National Center for Hydro-Meteorological Forecasting, the area from Da Nang to Binh Thuan, the Central Highlands and the South will have scattered showers and thunderstorms, locally heavy rain with rainfall from 15-30mm, locally over 70mm (thunderstorms are concentrated in the late afternoon and night).
According to the Southern Hydrometeorological Station, during October, the Southwest monsoon will gradually weaken, and the South will have several Northeast monsoons with a tendency to gradually strengthen until the end of the month.
Temperatures tend to decrease gradually. Heavy rain occurs in the first 20 days of the month, and the last days of the month see a gradual decrease in both area and volume of rain due to the strong activity of the Northeast monsoon during this period and its diffusion to the region.
From the night of October 6 to October 7, the area from Ha Tinh to Thua Thien Hue will have moderate rain and thunderstorms, with heavy rain in some places.
People and tourists need to be on guard against the risk of flash floods on small rivers and streams, landslides on steep slopes in the above province, especially in the districts of Bao Lam, Cat Tien, Da Huoai, Da Teh, Di Linh, Lam Ha, and Bao Loc City.
