"It was too bad for them - they were scared."

Ryan Gray, from the Coastguard, said: "Flood water up to 6cms in depth will take a human being off their feet and if it does so, it's very unlikely that the person will be able to stand up again."
"This was a metre and a half of flood water - it was lifting vehicles up and taking them down, the current of the water.
"There was a little bit of panic, thankfully the rescue teams are very well trained and they managed to calm the scene down and rescue people."
