Specifically, due to the increased activity of cold air, the tropical convergence zone with its axis maintained through the Central Central region combined with the East wind disturbance operating in the upper atmosphere at an altitude of 1500-5000m, therefore, from October 30 to November 4, the Central provinces will continue to experience widespread heavy rain, including: From October 30 to November 1, heavy rain will be concentrated in the area from Nghe An to the North of Quang Tri province (former Quang Binh province) with a total rainfall of 200-300mm, locally over 600mm.

"Current data does not show signs of extreme rain like the period of October 27-29. However, long-term forecasts from models are not highly reliable, so we need to continue monitoring and updating," noted Deputy Head of Weather Forecasting Department Vu Anh Tuan.
