New heavy rain warning issued by Met Office across flood-ravaged Britain

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 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.

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.

Rainfall totals for central/southern parts of the country were exceptional earlier in the week, representing more than a month's worth of rain in 48 hours.

Some places saw more than that - up to three month's worth of rainfall over the same period.

The last thing these areas need is further wet weather and yet, here we are, with another low pressure system spreading from the southwest.

Its travel northwards is unlikely to cause too many problems as it's moving quite quickly but it certainly won't help the flood recovery.

This rain system will stall over northern parts of the country tomorrow with the risk of some localised flooding and travel disruption.

However, as the rain returns south more slowly, it may deliver another inch or so of rainfall to precisely those areas that suffered earlier in the week and that's definitely a situation that requires close attention.

The weekend offers respite for all but the northwest as high pressure builds in - but a further storm system later on Sunday brings a further opportunity for heavy rain and strong winds.

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.
