A spokesman for the Met Office says it has been the wettest winter on record across England and Wales - where the precipitation records date back to 1766.
Some 435mm (17.1 inches) of rain fell from December 1 to February 24, beating the previous highest total of 423mm (16.6 inches) set in 1915.
Provisional rainfall figures show that the UK as a whole has had its wettest winter since records began in 1910.
Some 517.6mm (20.3 inches) of rain fell this winter, the previous highest total was 485.1mm (19.1 inches), set in 1995.
England and Wales endured the wettest winter in almost 250 years, according to new analysis from the Met Office.
Heavy showers are expected to strike most parts of the UK today, mainly in northern and western parts, but clear spells are also forecast.
The south-east of England may escape rain and remain clear and dry.
Temperatures are expected to be cold and windy.
On Sunday, early rain in north-east Scotland will ease to leave a day of sunshine and showers across the UK.
The showers will be mostly in western parts, these then giving way to more persistent rain in the south-west later - becoming less windy through the day.
ITV weather presenter Becky Mantin has the latest forecast:
The Environment Agency has issued more than 20 flood alerts for north England, the Midlands, the South East and Wales as heavy rain is set to lash the country.
The Met Office has also issued a number of severe weather warnings, for the Central, Tayside and Fife, London and the South East, south-west Scotland, Lothian Borders, the South West, Strathclyde and Wales.
It warned that heavy rain of up to 30mm (1.2in) will fall over high ground in Scotland during the morning, with thunderstorms and gusts of up to 60mph along the south coast of England.
Half a month's rain could fall in a single day in parts of the country this week.
The south west and Wales are likely to be the worst affected, with up to 25mm on Tuesday.
Towards the end of the week there will be spells of sunshine and showers, with temperatures climbing to 15C (59F) or 16C (61F) in London on Thursday and Friday.
