This is the dramatic moment a flash flood swamped a restaurant sending tourists running for their lives. <br /><br />Dozens of people had been gathered in the cafe at the Khao Yai National Park in Nakhon Nayok, Thailand, yesterday (August 13).<br /><br />But a sudden monsoon downpour caused a deluge and a stream burst its banks - sending tonnes of water gushing into a nearby seating area.<br /><br />The resort in the popular wildlife area was packed with locals who had the day off for a national holiday celebrating the country's annual Mother's Day. <br /><br />Hundreds of visitors were stranded after the downpour at different parts of the national park.<br /><br />Onlooker Wanruadee Wongpheung said: ''The water had come down from the river at the Nang Rong waterfalls. It was scary and I was worried about all the people who were there.''<br /><br />Hundreds of visitors were stranded in a resort inside the sprawling park with water levels too high for them to leave. They had to wait until evening when the water had subsided. <br /><br />Park official Wichai Pornleesaengsuwan said the flash flood was caused by heavy rainfall coming down from the mountains. <br /><br />He said: ''This is the worst flooding I have seen here for ten years. We are trying to ensure that everybody is safe and there are no injuries.''
