Parts of Northern Ireland under 3ft of water after heavy rain
Parts of Northern Ireland are said to be under 3ft of water due to heavy rain.
Parked cars have been stranded, shops and houses sand-bagged and traffic diverted in Newry, Co Down.
An area of Belfast close to the Lagan River has also been affected.
Newry and Mourne councillor John McArdle said he was wading through water in his Wellington boots, and added: "You would think you are in Venice, that's what it is like."
Police described Bridge Street through Newry as "impassable" to traffic.
Mr McArdle claimed he had never seen flooding like it, and added that two main shopping centres in the city were also badly affected.
A number of other roads have been closed, with the Lisburn and Moira area west of Belfast badly hit.
Police are advising motorists that the Hillhall Road, Lisburn, is flooded in both directions.
The rain has been accompanied by gales in places.
Northern Ireland could see 30-40mm falling on high ground tomorrow, a Met Office spokesman said. He added: "Because we have had a lot of rain we could see some localised flooding."
