Heavy rain could spark travel disruption across much of the UK, with a warning that flooding in some places could cause “danger to life”.
The Met Office has issued an amber warning for rain across parts of north Wales and northwest England, including Manchester and Liverpool, for 24 hours from midday on Wednesday.
Fast-flowing or deep floodwater is “likely”, according to the forecaster, and a good chance some communities could become cut off, suffer power cuts and see train and bus services cancelled.
A yellow warning for rain covers the north of England, the Midlands and north and central Wales until 6am on Thursday, while another is in place for southern and eastern Scotland from midday today until 6pm tomorrow.
Much of the south coast is likely to see lightning, with a yellow warning for thunderstorms in place from 8am until 7pm on Wednesday.
Chief meteorologist Andy Page said areas exposed to strengthening northerly winds are most likely to see the highest rainfall.
Northern areas are expected to remain cloudy and wet on Thursday, but southern parts can expect drier conditions, with sunshine becoming more widespread by the end of the week.
The news is better for bank holiday Monday, which is expected to be dry for much of the country, feeling warm in the sunshine.
A woman has suffered life-changing injuries after being stabbed by a member of the public at the accident and emergency department where she was working.
The victim – believed to be a nurse in her 50s – was attacked at Royal Oldham Hospital in Greater Manchester, where she is now being treated.
It is understood she was injured with a bladed article or a sharp instrument – and not by a knife.
Officers were called at 11.30pm on Saturday.
A 37-year-old man is in custody after being “swiftly arrested at the scene” on suspicion of attempted murder, Greater Manchester Police said.
Detectives are not looking for anyone else in connection with the incident and say there is no threat to the wider public.
Jim McMahon, the Labour MP for the area, described it as a “senseless attack”.
He posted on Facebook: “We are all shocked at the senseless attack on a nurse in the A&E department of the Royal Oldham Hospital.
“Our thoughts are with the nurse, family and friends as we wish a full recovery.”
Detective Sergeant Craig Roters said it was a “serious incident which has left a woman in a critical condition”.
The victim’s family and colleagues will be supported, he added.
The local community can expect to see an “increase in police presence” while enquiries are carried out, Mr Roters said.
“We know that news of this nature will come as a shock, and if you have any concerns or anything you would like to share, please speak to [officers].”
Conservative Party leader Kemi Badenoch has called on Sir Keir Starmer to sack Treasury minister Tulip Siddiq over allegations she lived in properties linked to allies of her aunt, Sheikh Hasina, the deposed prime minister of Bangladesh.
It comes after the current Bangladeshi leader, Muhammad Yunus, said London properties used by Ms Siddiq should be investigated.
He told the Sunday Timesthe properties should be handed back to his government if they were acquired through “plain robbery”.
Tory leader Ms Badenoch said: “It’s time for Keir Starmer to sack Tulip Siddiq.
“He appointed his personal friend as anti-corruption minister and she is accused herself of corruption.
“Now the government of Bangladesh is raising serious concerns about her links to the regime of Sheikh Hasina.”
Ms Siddiq insists she has “done nothing wrong”.
Her aunt was ousted from office in August following an uprising against her 20-year leadership and fled to India.
On the same day, the prime minister said: “Tulip Siddiq has acted entirely properly by referring herself to the independent adviser, as she’s now done, and that’s why we brought into being the new code.
“It’s to allow ministers to ask the adviser to establish the facts, and yes, I’ve got confidence in her, and that’s the process that will now be happening.”
Police in Aberdeen have widened the search area for two sisters who disappeared four days ago in the city.
Eliza and Henrietta Huszti, both 32, were last seen on CCTV on Market Street after leaving their home on Tuesday at around 2.12am.
The sisters – who are part of a set of triplets and originally from Hungary – crossed the Victoria Bridge to the Torry area and turned right on to a footpath next to the River Dee.
They headed in the direction of Aberdeen Boat Club but officers said there is no evidence to suggest the missing women left the immediate area.
Specialist search teams, police dogs and a marine unit have been trying to trace the pair.
Further searches are being carried out towards the Port of Aberdeen’s South Harbour and Duthie Park.
Police Scotland said it is liaising with authorities in Hungary to support the relatives of the two sisters.
Chief Inspector Darren Bruce said: “Eliza and Henrietta’s family are understandably extremely worried about them and we are working tirelessly to find them.
“We are seriously concerned about them and have significant resources dedicated to the inquiry.”
The sisters, from Aberdeen city centre, are described as slim with long brown hair.
Officers have requested businesses in and around the South Esplanade and Menzies Road area to review their CCTV footage for the early morning of Tuesday 7 January.
Police added they are keen to hear from anyone with dashcam footage from that time.
