Parts of the UK have already seen close to the whole month’s average rainfall in just the first nine days, with more rain spreading eastward across the country on Wednesday.
As clean-ups are ongoing for businesses and residents in the South East, rain is expected to be heavy and relentless in north-west England and western Scotland.
Flood warnings are still in place for East Wittering and the Bracklesham coast, Medmerry, Climping and Littlehampton Rope Walk in West Sussex due to high tides.
One person was taken to hospital after flooding at the Medmerry Holiday Park, between Bracklesham and Selsey, where 180 people were evacuated overnight on Tuesday.
Lee, from South Wales, who was staying at the site, told the that he woke up at 01:30 BST to find his bed was “rocking and floating on water”.
He said his van had also been submerged in water, and he had lost everything.
“I’ve lost all my tools and my two work laptops. My clothes were in my caravan too.”
