Speaking to the House of Commons today he said river levels has risen sharply on the River Severn, the Rivers Yarrow and Darwen in Lancashire and the Rivers Colne, Calder and Aire in West Yorkshire.
He said: "Reports are still coming in of the number of properties flooded from rivers and surface water but current indications are that this is of the order of 500.
"Some businesses have been affected and there have been a number of school closures, often because of transport problems rather than flooding of the school itself. Roads (including some motorways and trunk roads) and railways have been hit in the affected areas leading to delays."
However he said there had been no significant problems so far for essential services including water and power supplies.
One severe flood warning is still live from the Environment Agency, on the River Severn around Bewdley. Mr Benn said further severe warnings could not be ruled out due to more rain being forecast.
Mr Benn: "The risk of further flooding therefore remains high in some areas."
