Across the UK temperatures will once again plummet, with the potential of reaching well below freezing in some areas. This is forecast after this week’s yellow weather warnings for rain – which are in place across Tuesday, Wednesday and Thursday.
The remnants of tropical storm Sebastien are causing heavy rain across southern England, with Met Office weather warnings in place.
This could mean one to two inches of rain across some areas as the remainder of the storm passes across the UK.
The Environment Agency said: “Rain could lead to flooding in parts of the South, south Wales, East and North-East. Coastal flooding is possible on Wednesday on the south coast of Wales.
“Land, roads and properties could flood and travel disruption is possible.”

Met Office forecaster Marco Petagna said: “Remnants of Tropical Storm Sebastien mean it will be windy on Tuesday into Wednesday with gales in the South and South-West, and high spring tides.
“It’s not a pretty picture, with warnings for rain for the next few days after some places had three times their normal rain in the first half of the month.
“Colder air arrives at the end of the week, perhaps generally hanging on for the first half of December.”
Temperatures have risen compared to last week’s freezing lows – when the mercury plummeted to -9.9C in Braemer, Scotland.
This was the coldest temperature of autumn so far, and now conditions look to be returning to those levels.
The Weather Outlook forecaster Brian Gaze said: “It’s floods then freeze this week, with -5C possible by Saturday night and snow risks in the North.”
According to the Met Office, on Friday when warnings for rain have expired it will generally turn colder, drier and brighter but with sharp night frosts.
There will still be showers which will continue to affect North Sea coastal areas, and some rainfall may clip southwest England on Saturday.

The Met Office also forecasts cold polar air arriving from Friday which could remain for much of the next two weeks – with snow affecting the North and possibly the South.
On Saturday and into Sunday, it will be dry and cold for most with plenty of sunshine once any freezing fog patches clear.
A few coastal wintry showers are likely across northern and northeastern Scotland.
On Saturday it will be feeling cold with strong winds and widespread frost possible overnight away from the far south.
There is also a risk of gales in exposed areas.
The start of December looks to remain cold for many with overnight frost and fog possible with a risk of ice.
Any showers could be wintry in the north and over the hills at times further south.
Snow risk maps from NetWeather show heavy snow covering much of the UK at the beginning of December, with snow beginning in Scotland on December 2.
It will be heaviest in Scotland, before making its way to the North of England, Midlands, Wales and finally London and the South of England.
Snow will track southwards down the UK, covering almost the whole country in the white stuff by December 6.
Bitterly cold temperatures of -5C are set to appear by Saturday, November 30 in the North.
A Met Office forecaster said: “The beginning of December looks cold for many, with potential for wintry showers in the North, which may spread to higher ground in the South.”
