Early this morning, frost formed atop Mau Son peak in Lang Son province as temperatures plunged close to 0°C, creating a striking natural scene that drew in tourists and prompted local authorities to issue cold-weather warnings.

On January 22, Hoang Quoc Huy, Head of the Mau Son Meteorological Station, confirmed with VietNamNet that temperatures dropped to just 0.1°C at 8:00 a.m. today.

The freezing conditions, coupled with light rain and dense fog, caused a thin layer of frost to develop around 5:00 a.m. The ice gradually thickened, coating fences and meteorological equipment across the summit.

According to the Lang Son Hydro-Meteorological Station, a strong cold front continues to affect the region. The skies remain cloudy, with occasional drizzle. Following the rain, temperatures dropped sharply. Northeastern winds have strengthened, causing widespread cold weather. Regional temperatures range from 8–15°C, while Mau Son recorded temperatures between 2–7°C and humidity levels from 67–85%.

“Several tourists have already made their way to Mau Son to witness the frost,” said Huy.

Deputy Chair of Mau Son Commune, Dao Thi Mai Huong, noted that due to temperatures falling below 10°C, local authorities have suspended classes for kindergarten and primary school students to protect their health.

In response to the extreme weather, Lang Son’s Provincial Committee for Civil Defense issued a directive urging local authorities to closely monitor weather forecasts and provide timely information to communities. Leaders of communes and wards have been asked to review their emergency response plans and offer guidance to residents, particularly boarding school students, on how to stay safe in the cold.

Authorities have also warned against the use of coal stoves in enclosed spaces, which poses a risk of carbon monoxide poisoning.
