Flooding and landslides generated by tropical storm Kammuri have killed at least 100 people and left 50 others missing in northwest Vietnam, according to the Vietnam News Agency.

Because more rain is forecasted Monday, the officials are worried about future casualties.

Starting Friday, the geological phenomenon and rapid flooding of the low-lying areas have cut the main roads in the country’s northern mountain provinces neighboring People’s Republic of China.

Moreover, the heavy downpours damaged tens of thousands of homes in the mountainous regions, sweeping away a myriad of domestic animals, burying many inhabitants under mountains of mud and leading to the disappearance of an estimated 50 others, the country's news agency reported.

The natural phenomenon also hit down trees, as well as telephone and electricity lines in Lao Cai Province.

Local officials mobilized hundreds of troops in order to look for survivors and to help people in the areas most flooded by the weekend tropical storm. The rescue teams are using both trucks and boats to get to the occupants in the affected areas. They concentrate more on finding the people who were reported missing. 

"We have reached some areas that had been isolated for two days," Thao A Tua, Provincial disaster official told AFP, the largest French news agency.

"The water is receding but very slowly," stated official Luong Tuan Anh of Yen Bai province, where 29 people passed away. "Many villages remain unreachable by car."

Countless tourists were stuck in Lao Cai but local officials said none of them were among the killed or injured people.
