The flooding in West Yorkshire is the worst in 70 years authorities have said.
A ‘major incident’ was declared after more than 2000 homes were flooded and left without power.
Troops have been called in to assist emergency services in the hardest hit areas in Calderdale and Leeds.
West Yorkshire Police’s Assistant Chief Constable, Angela Williams, said: “The flooding situation we have experienced in West Yorkshire is quite simply the worst we have seen in 70 years, according to our partners in the Environment Agency.
“As a result we declared a major incident yesterday evening and received support from the Ministry of Defence who deployed 100 soldiers to assist with emergency and recovery efforts in Calderdale and Leeds.”
She added: “We want to thank members of the public for their support working with us, in what has been a truly dreadful and dangerous situation.

“Again, I’d advise residents to stay safe, try and stay upstairs in properties that are flooded and to ring 101 if they feel they are in danger.
“Please don’t try and drive through roads or over bridges which are closed due to flooding.
“They are closed because they are dangerous and we have had numerous calls from residents trapped in vehicles which have become submerged when they have tried to cross flood waters.
“Also, please don’t play in flood waters.
“The water will contain debris and maybe dangerous. Please help us help you by not putting yourselves in danger and by staying safe.”
In Leeds, the Kirkstall Road area of the city was badly affected, with flooding also reported in the Calls area, Leeds city centre.
Around 12,000 homes were also reported to be without power at one point with more than 20 roads closed.
