Revellers heading to Glastonbury Festival are "certain" to face another year of muddy mayhem, weather experts have warned.
Forecasters warn persistent rain throughout the week guarantees waterlogged scenes at Pilton for the second festival in succession.
Two years ago, after a month's rain fell in less than two hours, around 300 tents were washed away in floods.
To avoid a repeat this year, festival boss Michael Eavis has spent more than £750,000 (€1.1bn) on flood prevention measures, including new barriers.
Festival-goers will also be invited to leave their rain-soaked tents behind so they can be dried out and reused in impoverished countries.
Stephen Davenport, senior meteorologist for MeteoGroup UK, said the amount of surface water set to build up this week means mud baths are inevitable.
He said: "With the amount of rain that is about to fall in Somerset, it will be a mudfest.
"With heavy showers still around, and maybe thunderstorms, there will be more rain soon moving in tomorrow, heavy in the afternoon with thunderstorms again possible.
"We could be looking at a total of 60mm to 80mm (2.4in to 3.1in) of rain between now and the weekend - that's quite a deluge, so mud bath ahoy. Local flooding is likely."
The wet weather is expected to continue until the Arctic Monkeys headline the festival on Friday.
