As of October 6, cold air will dominate the weather in Northern Vietnam, leading to chilly nights and mornings, especially in mountainous areas. Meanwhile, Central Vietnam, from Ha Tinh to Hue, is expected to experience heavy rainfall, with some areas facing very heavy downpours.

The National Center for Meteorological and Hydrological Forecasting has indicated that the cold air will continue to influence the weather in Northern and North Central Vietnam. In the North, the weather will be cool during the night and morning, while the afternoon will see clearer skies and sunshine. However, rainfall will shift from the North to Central Vietnam, where heavy rain and thunderstorms are anticipated.

Forecasts suggest that the regions from Ha Tinh to Hue could receive rainfall ranging from 50 to 100 mm, with some areas exceeding 200 mm. There is a risk of intense rainfall exceeding 100 mm within three hours, which could lead to flooding in low-lying areas and urban centers. Additionally, the risk of flash floods in small rivers and landslides in mountainous regions is heightened.

During thunderstorms, there is a possibility of strong winds, lightning, and hail. The weather forecast for October 6 across various regions in Vietnam is as follows:
