Lifeboats have evacuated dozens of homes and offices in Rhyl after several hundred properties flooded during high tides and gale force winds.
The storm hit the north Wales coast, causing major disruption with roads closed, schools shut and trains stopped.
Two severe warnings - suggesting there is a danger to life - were issued for the area earlier on Thursday, but were later lifted.
Here is footage of the RNLI helping with the rescue in Rhyl.
