A drought has been declared in the West and East Midlands, the Environment Agency said.

Hot weather has left much of the UK in for a reprieve as the third heatwave this summer comes to an end.
Temperatures which have exceeded 30C in several parts of the country and broken multiple records over the weekend are widely forecast to cool.
Met Office meteorologist Greg Dewhurst said: "The heatwave is starting to come to an end as low pressure starts to move in from the Atlantic.
"We say goodbye to high pressure as this area of low pressure takes over, bringing bands of heavy rain, some thundery downpours, but also bringing in some fresher conditions across many parts."
As well as disruption to local communities as they brace for a scorching summer, British farmers have told GB News that they are feeling the strain of the lack of rainfall.

NFU Deputy President David Exwood highlighted the stark contrast in conditions facing farmers, which could result in yields being affected.
He told GB News: "After the wettest 18 months on record, we've now had one of the driest springs on record, and that's challenging because it means crops haven't grown. Development is slow, yields are going to be affected."
He noted that while the sunny weather has been enjoyed by Britons across the country, for farmers "that crucial spring period of planting and growth just hasn't given the results that it needed to."
Exwood, who runs a mixed arable and beef farm in Sussex, added: "If it remains hot and dry, it will get very challenging."
