The Environment Agency put a flood alert on the River Ouse at Barcombe and warned householders to be prepared in case they were flooded out.

A spokeswoman said: "The rainfall for the last few days means the ground is now soaked with water. It can't soak up any more and it is just running off into the rivers.

"Having said that, should the rain pass through as we are hoping the levels should drop naturally. But we are keeping an eye on the weather."

Storms and high winds were forecast to batter the countryside for the rest of the morning but die off in the afternoon.

Lighter wind and showers have been predicted for the next few days.

The scheduled ferry service from Newhaven to Dieppe at 8am this morning had to be cancelled due to winds of up to 50 knots.

Neither of the two Transmanche ferries had yet returned from trips to Dieppe yesterday because of concerns about the stormy conditions.

Karl Davenport, at the Transmanche Freight Office in Newhaven, said: "The weather over in Dieppe is not too bad, but here it has been probably the worst we've seen for quite a while."

He said they hoped to run this evening's 5pm service from Newhaven as planned.
