A strengthened cold front affected several locales in northern and north-central Vietnam on Wednesday before traveling down south.
This cold spell arrived in the mountainous provinces of northern Vietnam early Wednesday morning, the National Center for Meteor-hydrological Forecasting reported.
Under the effect of the cold front, northern Vietnam will experience drizzling rain that is forecast to taper off by the end of Wednesday, while north-central and mid-central provinces will see chances of heavier rain.
Chillier weather of 14 to 17 degrees Celsius, which could drop to 13 in high-altitude spots, will also dominate the northern area.
Hanoi residents will see temperatures ranging between 15 and 17 degree Celsius with chances of drizzle throughout the day.
Meanwhile, north-central Vietnam will see temperatures fluctuating between 15 and 18 degrees Celsius.
The cold spell also brings about northwest breezes of level 3-4 offshore and level 2-3 in inland areas, as well as chances of level 6-7 gale winds and rough seas in the Tonkin Gulf and the shoreline from Quang Tri Province to Ninh Thuan Province.
Catastrophe alerts of level two have been issued for rough sea situations caused by strong winds of up to level eight in the East Vietnam Sea including Vietnam's Hoang Sa (Paracel) Islands and Truong Sa (Spratly) Islands.
