Hundreds of people are stranded on New Zealand’s South Island after flash flooding spawned by heavy rainfall washed out the only roadway into an area popular with tourists.

The country’s weather service said parts of the island saw more than three feet of rain in the span of nearly three days, triggering landslides and inundating roadways.

The New Zealand Transport Authority released a video on Tuesday showing the extent of damage on Milford Road, the lone highway leading to Milford Sound, where more than 300 people, including tourists, are reported to be trapped.
