The tropical depression hit central Vietnam on Tuesday and brought heavy rains.

More rains are forecast for some parts of northern and central regions Thursday as a cold spell is moving from southern China to Vietnam, the disaster agency said. Also, adding another tropical depression was expected to hit the Philippines on Thursday evening and could strengthen to a tropical storm when it moves to the South China Sea.

Agriculture Minister Nguyen Xuan Cuong was quoted as telling a government emergency meeting Wednesday that it was the first time in a decade that northern and central regions suffered such a big volume of rains in a short period of time.

Rains of up to 50 centimeters were reported over the three-day period until Wednesday in some parts of central and northern regions.

Vietnam is prone to floods and storms which kill hundreds of people each year.
