An intensifying tropical storm called Kai-Tak (locally known as Helen) is forecasted to hit the northeastern East Sea on the tonight of Aug.16.

An alert has been issued to all boats operating on the sea.

According to the Central Hydrometeorological Broadcasting Centre, the storm's centre will be 880km east-northeast of Vietnam's Hoang Sa (Paracel) archipelago at 1pm Aug. 17. The storm is currently moving at 75-102km per hour.

The storm will affect the country's Truong Sa (Spratly) archipelago and southern coastal area from Binh Thuan to Ca Mau provinces. It will increase the chances of heavy showers in the country's northern, Central Highland and southern areas, while the central region continues to see scorching sun.

To cope with the storm's effects, the Central Storm and Flood Prevention and Control Centre has sent a message to provinces and relevant sectors to help boats reach land in time.

The storm will also cause rain in the Philippines as it passes over northern Luzon Island .

In recent days, heavy rain in the northern mountain provinces caused flooding and landslides, resulting in the deaths of two women in Son La and Ha Giang provinces. Many properties and paddy areas have reportedly been damaged although the extent of the damages has not been announced.-VNA
