Dozens of flood warnings are in place across England, with a yellow rain alert also due to come into force.

A flood warning means flooding is expected and “immediate action” is required, including turning off gas, water and electricity, moving items upstairs and moving family, pets and cars to safety.
An alert means flooding is possible and people should “be prepared” by packing a bag containing vital belongings such as medicines and insurance documents, and keep checking flood warnings.
There are no severe flood warnings, meaning a risk to life, yet in force.
The River Ouse through York is expected to peak on Monday evening with the Environment Agency warning people to avoid low lying roads and footpaths near the water.
Riverside properties in central Boston, Lincolnshire, are also at risk especially in the hours around the high tide due at about 08:20 on Tuesday.
Warnings are also in place along the coast in Cumbria and north-west England, the North East of England and Yorkshire, the south-east coast including Dover and Folkestone, and Cornwall in the south west.
BBC meteorologist Nikki Berry said the heavy rain would affect Wales and England over the next 36 hours until Tuesday evening.
It is coming from the south west and will reach northern England on Monday evening, where it will sit overnight before moving to southern England.
Many places will see between 15 and 25mm of rainfall but some areas could get between 30 and 50mm.
Ms Berry said the rain was “not especially unusual” but flooding problems will be exacerbated by previous heavy rainfall.
She said it was unconnected with Hurricane Lorenzo, which originated off the coast of West Africa and has been heading towards the UK.
There is “uncertainty” over what effect the storm, which will no longer be a hurricane by the time it reaches the UK on Thursday or Friday, will have as it may pass harmlessly to the north west, Ms Berry said.
