Organisers have apologised for pulling the plug on the MFEST music festival.
30,000 people had been expected at the event, which had been due to take place this weekend.
A music festival has had to be cancelled over safety concerns due to the adverse weather conditions.
The Human League, Texas, Bob Geldof and Cher Lloyd were all due to play at the two-day MFEST at Harewood House near Leeds.
Organisers said they were disappointed but had been left with no choice.
