A new weather warning for heavy rain has been issued by the Met Office which could cause further widespread flooding and travel disruption.
The yellow warning has been issued for much of England and Wales, apart from North Wales, parts of the West Midlands and the North West, between 5pm on Thursday and 10am on Friday.
The Met Office said “there is some uncertainty in the details” of this warning, but some areas could see up to 30mm (1.18in) of rain in two to three hours, and perhaps as much as 60mm (2.36in) of rain in four to six hours.
“Lightning and strong, gusty winds” might also be hazards in some areas, it said, as it also warned of potential power cuts.
“There is a small chance of fast flowing or deep floodwater causing danger to life,” it added.
Flooding forced 43 people to be evacuated from a Northamptonshire holiday park overnight.
Firefighters and police helped to move people away from rising floodwater at Billing Aquadrome.
West Northamptonshire Council said “a very limited number of people remain there”.
The latest weather alert is in addition to a previous yellow warning for rain which was issued for Thursday, lasting all day and covering much of the North East, stretching from Newcastle upon Tyne to Skegness.
For that warning, the heaviest rainfall was likely to be across the Pennines and North York Moors, the Met Office said, where as much as 100mm (3.93in) of rain could fall.

The warnings bring the threat of more flash floods after some places saw more than twice their average monthly rainfall in just 48 hours earlier this week.
Woburn in Bedfordshire recorded 142.8mm (5.62in) of rain, more than twice its average for the entire month of September, in just two days.
Meanwhile, the Environment Agency has 26 flood warnings in place.
These cover areas where flooding is expected in Oxfordshire, Buckinghamshire, Northamptonshire and Bedfordshire.
