COCKERMOUTH, England (AFP) – Britain's flood-hit northwest braced Saturday for more devastation after river levels rose again and forecasters warned of more rain following unprecedented torrential deluges.

Prime Minister Gordon Brown surveyed the grim aftermath on a visit to the badly hit town of Cockermouth, with houses filled with muddy water, silt and sludge carpeting the roads and cars left awkwardly where the floods left them.

The floods forced hundreds of people out of their homes and left a policeman dead after the bridge on which he was standing was swept away.

Some 314 millimeters (12.3 inches) of rain fell in 24 hours – the highest level since records began – over the county of Cumbria as torrential rains swept across Britain and Ireland this week.

In Devon, southwest England, a canoeist also died after being pulled from the River Dart, which was swollen by the heavy rains. The 46-year-old man became trapped against a tree, emergency services said.

Meteorologist Paul Mott said more rain was expected on Sunday and in subsequent days, adding: "Some will be quite heavy and there will be more prolonged showers on Tuesday.

"But it's not going to be nearly as heavy as Thursday – it’s just going to be a very slow recovery."

The Environment Agency said river levels were rising again in Cumbria and the emergency services once again urged people not to go back to their homes.

An estimated 1,300 homes have been affected by flooding across the region, 1,000 left without power, and hundreds of people displaced. Almost 70 people remained in temporary accommodation late Saturday.

Brown met people unable to return home at a reception centre in a hotel in Cockermouth, which lies on the edge of the scenic Lake District, and pledged an extra one million pounds ($1.65 million) to help flood-hit communities.

"This is the second time I have been flooded out, in 2005 I was out for six months. This time it’s hopeless. I don't know when I will get back home," said 88-year-old Doris Studholme.

"I've lost everything again. Last time they had to carry me out, this time they came quickly and got us out before the flood."

Four bridges collapsed in the area, including one in the coastal town of Workington which was swept away on the raging waters of the river Derwent.

Policeman Bill Barker, who was due to celebrate his 45th birthday on Saturday, was directing motorists away from the bridge when it collapsed on Thursday. His body was recovered on a beach downstream.
