She said: “The River Ouse is expected to peak at 5.3m above normal summer levels tomorrow lunchtime. Around 500 properties are directly affected by the flooding at present and the emergency services, the Environment Agency, City of York Council and the Armed Forces are working around the clock to protect and support the city and its residents. I would like to thank everyone who has worked so hard over the last few days, including residents and volunteers.

He said the water was waist-deep when he left.
The man, who was at an emergency rest centre at Archbishop Holgate’s School, said: “It’s not been a very nice night. I’ve had about 40 minutes sleep. Not a great way to spend Christmas.”
The Pallister family arrived at the centre with four children, who were still wearing their pyjamas.
They said the rescue services had been “really good” and checked on the family throughout the night.
Lisa Pallister, 36, said the water had not yet entered their home in the Huntington area of York but was expected to rise further during today.
She said: “We didn’t think it would reach us because we’re raised off the ground and have three storeys but, by this morning, it was on the steps and it is going to rise by lunchtime. So we had a boat ride out.
“We’re feeling all right. A bit tired, a bit shocked. We’re lucky though, a lot of other residents were flooded last night early on.
“The children have coped really well, they’ve been really brave, we were rescued out of there and they were brave.”
Mrs Pallister said they were now going to stay with parents until they could get back into their home. She said the school rest centre was full of evacuated residents when they arrived. Dozens of mountain rescue teams from across the north of England gathered in the car park.
