But a mass of cold air is expected to arrive in mountainous regions in the north starting Wednesday afternoon, before reaching other parts of northern Vietnam, according to the National Center for Hydro-Meteorological Forecasting.

North-central regions would also feel the brunt of the mass of cold air starting Wednesday night, with temperatures plunging down to 16-19 degrees at the lowest.
