The Environment Agency warned that flooding from major rivers could continue into Tuesday amid widespread disruption from Storm Babette, which is causing “life-threatening” conditions in some areas.
Three people have died since the storm hit the UK on Wednesday, while a search continues in Aberdeenshire after reports of a man trapped in a flooded vehicle.
Flooding has caused travel disruption across Britain’s rail network, with train operators advising customers not to travel on Saturday.
The Environment Agency (EA) has announced three severe flood warnings for areas around the River Derwent in Derbyshire. This means that deep, fast-moving water not only poses a significant risk of death or serious injury, but also causes significant disruption to local communities.
Catherine Smith, EA’s flood duty manager, said: “Severe river flooding is expected to affect parts of the East Midlands and South Yorkshire from today into Sunday following continued heavy rainfall from Storm Babette. There is a possibility that it will.”
“Severe river flooding impacts are occurring on the River Derwent in Derby, where we have issued a severe flood warning, and other locations across the Midlands and parts of the north of England are also experiencing significant flooding today. There is a possibility that it will come out.
“Flooding is likely to continue on some large rivers, including the River Severn, River Ouse and River Trent, until Tuesday.”
The EA has issued more than 300 flood warnings with a low risk of flooding across England since Thursday, with the highest numbers in Yorkshire and the East and West Midlands.
As of Saturday afternoon, 275 warnings were still in effect, while authorities said 237 flooded properties had been reported and a further 20,000 were protected by defences.
Scotland has also been badly affected, with a red weather warning warning of danger to life in parts of Angus and Aberdeenshire for the second day in a row.
In Wales, a severe flood warning has been issued for the village of Llandrinio in Powys and isolated areas of land at the junction of the Severn and Winwy.
Power outages caused by Storm Babette affected about 100,000 customers, but 96% had been reconnected by Saturday morning, leaving 4,000 customers without power, according to the Energy Network Association.
A man in his 60s died after being caught in rushing floodwaters in the Shropshire town of Cleobury Mortimer on Friday.
Police Scotland previously announced that a 56-year-old driver was killed when a fallen tree hit his van near Forfar, Angus, on Thursday night.
On Thursday, a 57-year-old woman also died after being swept into a river in the area.
