Thousands of people were forced to leave their homes due to a deadly storm, which struck Canada’s Vancouver on Monday.
Local officials described the storm as a once-in-a-century weather event.
At least one person died, while two other people went missing.
RCMP Sgt Janelle Shoihet said that rescuers had not yet determined the number of the lost vehicles in the slide.
Motorist Kathie Rennie told CBC News she saw the landslide come down on traffic that was already at a standstill south of Lillooet.
“No sooner do we get back into our vehicles, the people that were in front of us are just screaming and running,” she said. “The look on their faces, it was like a tsunami was coming. It was the scariest thing that I’ve ever seen.
“I just turned around, and I’m just watching the whole side of the mountain coming down and taking out these cars… everything swept away. Just complete panic.”
The deadly storm comes after British Columbia suffered a record high heat wave over the summer that killed more than 500 people, and wildfires that destroyed an entire town.
Earlier this month, a tornado hit British Columbia – the first time one hit the area in five decades.
