Strong winds and large waves are expected to cause further coastal flooding on Monday.
The Environment Agency issued one severe flood warning in Dorset - meaning "there is significant risk to life" - and 87 flood warnings where flooding is "expected" across almost every region in England and Wales.
The Met Office issued a "be aware" yellow warning for wind as gusts of up to 70mph are expected on the west and south-west coast of Britain and the east coast of Northern Ireland.
This will cause ''exceptionally high waves'', the Met Office predicted.
Transport network has been hit
Heavy rain fell across much of the UK on Sunday night, with up to 1.6in (40mm) expected on higher ground.
The Environment Agency estimates that about 220 properties have been flooded so far as miles of coastline have been battered and roads and fields across the country are under water.
The transport network has also been hit, with roads closed and trains delayed or cancelled in many areas.
First Great Western warned passengers there was a risk to services in Cornwall, Devon, Somerset, Wiltshire and Dorset.
The Thames Barrier was in operation on Sunday night to protect people and property along the river.
'Significant flooding' expected
In Oxford a 47-year-old man died when his mobility scooter fell from a flooded path into a river.
Thames Valley Police were called to Osney Lock near the city centre at 6.30pm on Saturday after receiving a report that the man had fallen into the river.
A police spokesman said the man's death was being treated as unexplained but was not believed to be suspicious. His next-of-kin has been informed.
The Environment Agency (EA) urged communities in Dorset and Oxfordshire to remain prepared for ''significant flooding'' in the lower reaches of the Thames, Dorset Stour and Frome rivers.
Ongoing flooding is expected on the Somerset Levels and rivers in the South East, including the Severn, remain ''very high'' after recent rainfall.
Jonathan Day, flood risk manager at the Environment Agency, warned that the risk of flooding continued this week.
Public urged to be prepared
He said: ''Although high tides are now falling, there remains a risk of coastal flooding, especially on the south and west coasts.
''In addition, wet conditions have left the ground saturated in many areas, increasing the risk of river and surface water flooding.
''We would urge people to be prepared by checking their flood risk, signing up to free flood warnings and keeping an eye on the latest flood updates via the EA website and Twitter.
''Environment Agency teams remain out on the ground across the country and will continue to work around the clock to protect communities at risk."
