According to the National Center for Hydro-Meteorological Forecasting, on September 10, a cold air mass is approaching the northern border of Vietnam. This weather change is expected to bring significant drops in temperature across the region.

In particular, areas in the northeastern mountainous and midland regions may see scattered rain showers and thunderstorms, with some places experiencing heavy rainfall. The cold snap is anticipated to lower temperatures to below 19 degrees Celsius in certain locations, marking the onset of the autumn season.

Residents are advised to prepare for the chilly weather, especially in the evenings and early mornings when temperatures are expected to be at their lowest. The cold air will also bring about changes in wind patterns, contributing to a more pronounced autumn feel in the region.

As this weather system develops, local authorities are urged to monitor the situation closely and provide timely updates to the public to ensure safety and preparedness against potential weather-related disruptions.
