A mountain pass in south-central Vietnam has become congested with traffic between provinces in the area because of serious landslides.

Repeated mudslides triggered by prolonged rain at the Khanh Le Pass since Saturday morning has blocked traffic between the tourist city of Da Lat in the Central Highlands and the beach city of Nha Trang in south-central Khanh Hoa Province.

Local authorities had to prohibit all vehicles from traveling on the route to ensure safety and deal with the situation.

According to Ta Thanh Tinh, an official from the Directorate for Roads in Vietnam, the rain started at around 5:30 am, causing rocks and mud to fall onto the pass.

Landslides occurred three times on Saturday morning and again in the evening, with the amount of rock estimated at 7,000 cubic meters, Tinh continued.

“As rain continued throughout the day, there are high risks of flash floods and landslips,” the official added.

The bad weather conditions have posed immense challenges for competent authorities to ease traffic congestion.

The Khanh Le Pass is 1,700 meters high and 33 kilometers long, being part of the over 120 kilometer long National Highway 27C, which is the essential route connecting Da Lat and Nha Trang.

The pass snakes around the mountain and consists of multiple curves and sharp turns.

On November 24, a couple were washed away by flash floods brought about by heavy rain as they were traveling on the mountain pass.

The body of the woman has been found while the man remains missing.

Due to an enhanced cold front, heavy downpours are forecast to continue from the north-central province of Ha Tinh to the south-central province of Phu Yen on Sunday, according to the National Center for Hydro-meteorological Forecasting.
