Britain has been drowned in torrential rain over the past 24 hours, causing widespread flooding throughout the country and chaos for millions of people. The Met Office issued a yellow weather warning for a large swathe of Southern England for Wednesday evening and into Thursday morning as downpours battered the UK. Temperatures have also plummeted into single figures and conditions are forecast to be generally unsettled over the weekend, with a broad range of dry and rainy weather.
But in an alarming sign, the latest weather charts show a huge Atlantic weather front quickly travelling eastwards towards the UK over the weekend.
This could smash into the UK as soon as Monday afternoon, significantly increasing the chance of prolonged periods of torrential rain.
Met Office meteorologist Alex Deakin said the pattern of the Atlantic jet stream appears to be north-south, “which is very evident indeed”.
He warned low pressure areas will be driven in by the jet stream towards northern areas of the UK, which will trigger periods of rain throughout the country.
But he warned that with this “amplifying jet stream, that could mean things get stuck”, which could bring with it “persistent rain for a number of days”.
Mr Deakin said: “On Monday, there is low pressure nearby and a weather front sitting across the UK.
“But the jet stream isn’t really engaging with the low pressure and is staying to the south.
“The pattern of the jet stream is more north-south, particularly in the Atlantic, which is very evident indeed.

“There is the possibility of one weather system just lying across the north of the UK and getting stuck, which could bring persistent rain for a number of days.”
The Met Office warned in the latest forecast on its website there will be heavy rain across the northwest of the UK and “more organised showers” forming across the southwest.
This rain will continue into Tuesday “before more prolonged, organised rain arrives”.
The rest of October is forecast to be dominated by more unsettled weather coming in from the Atlantic, with the north and west of the country taking the biggest hit.
The Met Office said: “Sunshine and scattered showers to start to the period on Monday, these showers will be mostly widespread and heavy in the northwest.
“More organised showers potentially developing in the southwest.
“Winds will be moderate to fresh for most.
“Showers continuing in the west on Tuesday before more prolonged, organised rain arrives.
“Temperatures trending upwards through the first few days of this period before they remain just above average.
“The rest of October will be dominated by weather arriving from the Atlantic.
“Often unsettled and windy, with outbreaks of rain. Wettest in the north and west.
“Briefer dry interludes. Driest conditions likely across south and southeastern areas. Winds lighter here, with risk of overnight fog at times.”
