UK floods: River levels rise as rain and wind sweep in
Thousands of sandbags are being piled up to protect homes and businesses as more heavy rain and gale-force winds sweep across southern Britain.
With river levels expected to rise, the Environment Agency has made 30,000 sandbags available to properties near the Thames in Berkshire and Surrey.
Princes William and Harry have helped pile sandbags in Datchet, Berkshire.
All train services west of Plymouth are cancelled for the rest of the day, and there will be no replacement buses.
First Great Western said coach companies had refused to run rail replacement services in Cornwall due to the "unsafe" conditions.
In Wales, more than 16,000 properties remain without power following Wednesday's winds of up to 112mph.
A man has died in hospital after being hit by a falling tree in his garden in Gwynedd during Wednesday's storm.
The Environment Agency has issued 24 severe flood warnings covering parts of Cornwall, Devon, Somerset, Dorset, Gloucestershire, Hampshire, Berkshire and Surrey.
The latest warnings are for various places along the south coast of England.
The Met Office said that following the heavy rain that had fallen in many places during the day, it expected "potentially damaging" severe gales in southern England during the evening and into Saturday morning.
Snow has started falling in parts of northern England, Northern Ireland and parts of Scotland.
BBC Weather's Peter Gibbs said that with gusts of up to 80mph likely, there was a danger of high tides bringing fresh coastal flooding.
The weather is expected to gradually improve on Saturday, the Met Office says, leaving a better day on Sunday and "less intense" showers on Monday.
The Environment Agency said flood levels on the Thames had "stabilised in the last 24 hours", but the latest rainfall would cause levels to rise again and stay high for several days.
Programme director Peter Willison said: "This remains a very live event. I expect we will see further property flooding."
Alex Tribick from the Spelthorne Business Forum in Surrey said the local currency had "changed from the pound to the sandbag".
Earlier, Prime Minister David Cameron said the government would "fight at every front to help people" hit by floods.
He said money would be no object in a "massive national effort", saying: "I want people to know that the government absolutely stands behind this relief effort."

Some parts of the Somerset Levels have been flooded for several weeks, while areas near the Thames in Berkshire and Surrey have seen major flooding in recent days.
As well as the 24 severe flood warnings, the Environment Agency has issued more than 400 less serious flood warnings and alerts, mostly in southern England and the Midlands.
In addition to the cancellation of all trains in Cornwall, there is widespread disruption on UK railways and Network Rail is advising customers to check before travelling.
Some roads are closed because of flooding. See BBC Travel News for more.
Meanwhile, a Royal Air Force (RAF) Tornado jet has captured detailed aerial pictures of areas affected by the floods.
High-resolution imagery captured from the aircraft, deployed from RAF Marham, in Norfolk, will help in the planning of relief operations.
Defence Secretary Philip Hammond said: "This Tornado-borne surveillance capability is very much proven in a combat role in Afghanistan but its versatility is underlined by its use today, here at home, to support ongoing flood relief efforts."
