Three people have been airlifted from a caravan park after serious flooding in West Wales, the fire service said.
Royal Air Force Sea King helicopters, inshore life boats and fire service rescue boats are in attendance at the Riverside Caravan Park in Llandre, Bow Street, near Aberystwyth, where "numerous people" need help.
The Mid and West Wales Fire and Rescue Service said: "There is large amount of water and a heavy current running through the caravan park."
The spokesman said: "Numerous people are surrounded by flood water and are requiring rescue by fire service boats, inshore life boat teams and RAF helicopters.
"At the moment three people have been rescued by Sea King helicopter there. There are approximately 20 fire service personnel in attendance with boats."
He said the caravans are all static and touring types.
Another 11 people are waiting to be rescued at the nearby Mill House Caravan Park at Dol-y-Bont, also in Llandre.
The spokesman said there were around 75 fire service personnel in the area, in 15 fire appliances and three or four fire boats.
About 4-5ft of water was flowing through the main street in nearby Talybont, where about 30 people were sheltering in the community hall and a local pub after being rescued.
The spokesman added people were waiting to be evacuated from around 25 more properties.
