There are fears the dam near Rotherham could collapse

You can read a selection of comments and reports below.

Philip: "I had to walk eight miles in the rain yesterday as my car packed in. I waded through three feet of water. Then, I had to wait on top of bus shelter as the rain got worse and the current got stronger near the main road at Magna.

"It was like a disaster movie. Plus we had no electricity all night either."

Keith: "We were woken up by our daughter at 3.30am. She had been ordered to leave her house in Whiston, Rotherham as the Ulley Dam was expected to burst. She came to stay with us.

"Her neighbour was having difficulties in finding the evacuation centre so now my daughter and her two boys have gone to her mother-in-law's house. We are accommodating the neighbour and her husband and two children.

"The little one - who is only two - thinks she has gone on holiday. Let's hope she it will be a short one."

Lisa: "I was without power for most of day and night and unable to even cook tea for my little boy.

"My husband went away with work and cannot get home because of chaos on the railway, and I can't reach my parents who live in Sheffield, so I am feeling a bit alone. My aunty had to wade home through waist deep water with the territorial army yesterday after being stuck on the bus in Sheffield for over five hours.

"I am just holding my breath now and hoping the nearby Ulley Reservoir doesn't burst."

Danny Savage, BBC North of England correspondent: "Flood waters, abandoned cars and an eerie silence.

"The centre of Sheffield has been washed out by the floods and its infrastructure has taken a terrible battering.

"The Meadow Halls Shopping Centre stands like a moated castle with its carparks underwater.

A nearby main route into the city is littered with cars caught in the torrent. Some of them are lying on top of each other, and all are filled with water and mud - completely written off.

"At its peak, the water in Brightside Lane - home to many businesses - was six feet high.

"Most of it has now subsided, leaving myself and anyone else around to pick up stranded fish and throw them back into the River Don.

"A few miles away, in the village of Catcliffe, the waters are still rising. More than 30 homes have been flooded this morning, as the River Rother burst its banks.

"The local pub, The Plough, has only been reopened for a few weeks. As well as being under new management, it's also underwater."

Severe weather: Yorkshire pictures

David: "I was coming back from Birmingham, on a journey that normally takes two hours. It took me 7-8 hours.

"Half of Sheffield looks like a warzone, the other half looks like scenes from Water World. Living on the outskirts of Sheffield, I had a tough task of getting home. I was able to get home, it just meant turning off the computer route planners and flipping through my A-Z to find the back routes in and out of the city."

Beatrice Brennan: "Just a word of thanks for a bus driver called Steve, who drove my son and his friends all over Sheffield from his school. The bus left school at 3.30. The children arrived home at 8.45pm! It usually takes one hour."

Ben Brown, BBC correspondent, whose car was swamped by floodwaters: "We tried to drive through the water and then broke down, so we had to abandon it.

"We got through with someone in their Range Rover which got us through the next bit of water."

Matt: "My wife works at the Northern General Hospital - a three mile drive from where we live. It took her three hours to drive one mile last night whilst endeavouring to get there for a night-shift.

"In the end, she was turned back by police as water had cut off the area. Staff at the Northern General have been working 24 hours straight simply because no one can get near it and no one can leave."

Sarah Carter, East Halton: "I was in the middle of this mess. I had to walk through a foot of water to get to my parked car. I drove slowly through three washed out roads. They closed down the entrance to my village and so I wasn't able to get home.

"I took shelter in the office of an oil refinery and stayed the night with family. I only arrived home at 10am this morning."

Jim Cooper: "The water came from a completely unexpected direction, completely flooding the garden and patio. After 10 years of living here we've seen nothing like it.

"This morning there is something of a surreal carnival feeling in the street - with kids playing in the sodden ground. But the water was only a few inches from the house yesterday. So it could easily have been less of novelty and more of a disaster."

Keith, Stickney: "Sadly, my school couldn't keep the flood water out and 80 pupils missed their GCSE Science exam."

Phil Mackie, BBC correspondent: "The River Teme is one of the big rivers that's really filling up with the overspill from the brooks, streams and smaller rivers which burst their banks yesterday.

"It's smashed through the bridge at Ludlow in Shropshire before pouring into homes and shops in a wide area in Tenbury Wells in Worcestershire.

"The town centre has been cut off, but the waters are beginning to recede.

"The Environment Agency issued a severe flood warning last night, giving businesses and householders some valuable time to save their belongings ahead of the rapidly rising flood waters.

"The local high school has been turned into a reception centre for dozens of people who had to leave their homes.

"As a consequence, the town is filled with children enjoying an unexpected day off school. They are wading through the murky, brown, waist-deep water.

"The flood surge on the Teme is now heading downstream towards Worcester.

"It's expected to merge with a similar surge along the River Severn which is threatening the towns of Upton upon Severn and Tewkesbury."

Neil: "I drove back from Ashby to Wakefield last night - the journey was horrendous! I left the M1 and cut across to the A1 at Doncaster. I have never seen rain and floods like I witnessed yesterday.

"A big thank you to those drivers who adapted their driving to suit the conditions. However there were still a few who insisted on tearing down the road with little or no regard for fellow road users or the conditions."

Emma: "My brother went to South Elmsall and told us that cars were completely underwater - with only their roofs poking out. My boyfriend is at his friends' house and round their street there is up to three feet of water. It's crazy I have exams at college this week and all the buses have stopped!"

Sally: "I didn't get home at all last night. I was stuck in traffic for four hours. I finally managed to get to a friend's place one mile from where I work and stayed there.

"Many of my colleagues were stuck at work overnight and watched the RAF rescuing people from nearby factories. I need to get home - although I don't know how - to see that my cat's OK."
