Brits look set for five more days of torrential rain following downpours which have caused major flooding and forced hundreds of people to flee their homes.
There will be no let up in the showers that have seen Scottish Border areas worst hit and even two road bridges washed away near Dumfries.
Residents have been evacuated from flooded homes and roads and rail links blocked, causing travel chaos.
ScotsRail said the rail line between Dumfries and Carlisle "will be closed until further notice" and rail replacement transport has been requested for Friday morning.
The incident happened after a major incident was declared in Hawick with up to 500 properties feared to be at risk of flooding.
The Met Office tweeted there has been 370mm of rain recorded at Honister Pass in Cumbria between 1am on Wednesday and 6pm on Thursday.
It reported 132mm of rain at Eskdalemuir in Dumfries and Galloway in the same period.
And there are currently 65 flood warnings and alerts in England and a further 21 in Scotland.
The Met Office is predicting persistent and heavy rain on Friday which could become drier by the afternoon with a risk still of heavy showers.
Then looking to weekend maps from WXCHARTS and Netweather and there is a massive band of heavy rain coming in from the Atlantic on Saturday morning.
While those downpours are expected to ease for much of the country during the day, Sunday will start again with fresh showers and head across the country from the west.
AccuWeather senior meteorologist Tyler Roys warned the UK could be drowned in five inches of rain this weekend, with torrential rainfall forecast for both days.
He told Express.co.uk : "Generally, 0.75in (38 mm) to 3in (75mm) of rain will occur Saturday and Sunday across the UK with highest amounts in southern England, Midlands and Wales with the AccuWeather Local StormMax of 5in (125mm)."
Met Office meteorologist Aidan McGivern also warned another weather system will quickly approach the UK on Saturday, pushed though by an Atlantic jetstream.
He said: "It's not long before another system turns up, carried along by the jetstream.
"You can see two streams with this jet stream, one of them engaging some warm air towards the Iberian peninsula and developing some wet weather systems there and another pushing systems through to the UK.
"There is a chance this initial front moving in for Friday night there's a chance some of this activity to the south, some of this warm air and the jet stream, could develop it further."
The Met Office is predicting rain every day from Friday through Tuesday, with gales possible early next week.
