Britain's heatwave is set to be washed away by heavy rain, but it could be more of a curse than a blessing as dangerous flash flooding is also expected. We have the latest warnings and forecast from the Met Office. But first, the headlines...

New Covid jab | The UK is the world's first country to authorise an omicron-specific booster vaccination, with an updated version of the Moderna jab set to be available in time for an autumn campaign.

The big story: Thunderstorms set to sweep Britain
After the latest heatwave, comes the rain, storms – and floods. The Met Office has warned that an "incredible deluge" expected in the UK over the next few days would hit hard ground and could cause flooding within an hour, with people urged to pack up their valuables now and move them to a higher level.
A yellow warning for thunderstorms is in place across Monday and Tuesday, but meteorologists said it is not clear exactly where the storms will strike.
Up to 50mm (2in) of rain is expected within two hours in some parts – a volume that is likely to flood low-lying areas quickly.
Met Office spokesman Grahame Madge said anyone travelling by car should be "prepared to get stuck" and expect flooded roads and run-off from fields. Environment correspondent Olivia Rudgard has the latest warnings and weather forecast.
It comes after weeks of little rain and warm conditions have caused droughts in large areas of Britain, leaving land parched. See some of the most striking pictures and search for water restrictions by postcode.
With fears over the drought ravaging British crops, farmers say shoppers must be prepared to buy wonky vegetables.
The National Farmers' Union urged people to "pull together" and accept buying wonky vegetables, as the lack of water threatens to produce shrunken onions and potatoes that might not ordinarily meet supermarket quality standards.

'If you can see me, weep'
As drought continues to also afflict Europe, severe dry conditions have caused water levels of the river Elbe to drop – exposing centuries-old "hunger stones" that are embedded into the banks to mark water levels during famines.
One stone, now visible in Děčín, where the Elbe flows from the Czech Republic into Germany, was carved with a warning in 1616 that reads: "If you see me, weep."
Read about other stones, which were common from the 16th to 19th centuries, that have been exposed with inscriptions with similarly macabre warnings.
The hobby enjoying a boom
There is, at least, one positive to come from the drought: there has never been a better time to go mudlarking.
If you are unfamiliar with the hobby, it involves sifting through river banks for lost items of value or historical significance – and it has made a comeback during the recent high temperatures.
India Sturgis explains how the lack of rain that has caused water levels to drop means the activity is enjoying a boom.
