The latest weather warning issued for this week. Pic: Met Office 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 the forecaster also warned of potential power cuts.
“There is a small chance of fast flowing or deep floodwater causing danger to life,” it added.
Firefighters evacuate dozens
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 holiday park.
Instead, residents spent the night on camp beds in a nearby leisure centre.
Speaking outside the leisure centre on Wednesday, one man said it was unclear when they would be able to return.
A female resident added: “We are without a home at the moment but it was better to be safe than sorry.”
West Northamptonshire Council said “a very limited number of people remain” at the park.

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 dozens of flood warnings in place.
These cover areas where flooding is expected in Oxfordshire, Buckinghamshire, Northamptonshire and Bedfordshire.
