The fire service's Kevin O'Neill said it was the most severe flooding he had ever dealt with.
"We have had all our crews out since virtually two o'clock yesterday afternoon and all through the night dealing with incidents relating to flood water," he said.
"I don't think we've either seen a time when the flooding has been as devastating as this or has affected the road transport as badly."

"The water was as high as the pumping station outside," she said.
