Tropical storm Kai-Tak has entered the East Vietnam Sea and become the country’s 15th storm of the year, while a cold front continues to produce low temperature across the country.
The typhoon, which had formed off the central Philippines, was located about 430 kilometers southeast of Song Tu Tay Island, part of Vietnam's Truong Sa (Spratly) Archipelago, as of Monday evening, according to the National Center for Hydro-meteorological Forecasting.
Average wind speed was between 60 and 75km an hour, with gusts reaching 100km per hour.
The storm was forecast to travel southwestward at a velocity of 15km per hour.
By 7:00 pm on Tuesday, Typhoon Kai-Tak is anticipated to be 230 kilometers south of Song Tu Tay Island, and continue its southwestward journey over the next 24 to 48 hours.
It is expected to reach the southern part of Truong Sa on Wednesday evening, packing winds of 60 to 90km per hour and squalls of up to 117km an hour.
According to Le Thanh Hai, deputy director of the weather forecasting center, the storm may not make landfall in mainland Vietnam and instead travel toward Malaysia, reducing the chances of it affecting Vietnamese townships.
However, rough seas and strong winds can be expected in the maritime area east of Truong Sa, Hai added.
Additionally, a prolonged cold spell has influenced most provinces and cities across Vietnam and is expected to remain until Wednesday.
Average temperatures in the northern region have been between nine and 11 degrees Celsius.
Mountainous areas such as Sa Pa Town, Lao Cai Province, and Mau Son Commune in Lang Son Province have experienced temperatures as low as two to four degrees Celsius.
Southern Vietnam has also entered its coldest time of the year, with temperatures dropping under 20 degrees Celsius at night and in the early morning.
