Environment Agency workers spent the early part of the day clearing river blockages ahead of expected heavy rain.
Dave Throup, of the Environment Agency, said the "weather window" of dry, calm weather had given staff the chance to prepare for later.

"The compounding factor is half of that might fall in the space of an hour," Mr Throup said.
"This could lead to surface water, which will find its way quickly into the rivers which have not yet had a chance to recover from yesterday's rain."
