The National Hydro Meteorological Forecasting Centre said that a milder cold front has now moved into northern Vietnam, bringing much needed relief from the scorching heat in the northern and central regions.
Temperatures reached 37-39 degrees Celsius in the above regions on Monday, and expect to reduce to 28-30 degrees Celsius.
The cold front has caused showers and scattered thunderstorms across the northern and north-central regions. Northeasterly winds have gradually intensified at 30-38 kilometres an hour in the Gulf of Tonkin by this morning, Tuesday.
By this afternoon and night time, the cold front will spread across the south-central region and result in showers and thunderstorms in some places.
The southern region is at present cloudy and wet with temperatures lower than in the northern and central regions. Ho Chi Minh City from Tuesday noon will see medium to heavy rainfall with mercury hovering around 23-24 degrees Celsius.
