Sodden communities along the River Thames are bracing for more floods as Britain counts the cost of a storm that's claimed several lives and left tens of thousands of homes without power.
At least three people were killed in separate incidents in Ireland, Britain and the English Channel after violent winds and heavy rain swept in from the Atlantic on Friday.
Pulling down power lines and disrupting transport networks across the region, the storm brought fresh misery to flood-hit communities in Britain, parts of which are suffering their wettest start to the year for 250 years.
Prime Minister David Cameron warned on Saturday that the worst was not yet over as he visited the Thames-side village of Chertsey, west of London, to see how the military were helping bolster flood defences.
"What we do in the next 24 hours is vital because tragically the river levels will rise again. So every sand bag delivered, every house helped, every flood barrier put in place can make a big difference," Cameron said.
More than 3,000 members of the military are involved in the flood relief effort, according to the defence ministry, as the government seeks to counter criticism that it was too slow to respond to the crisis.
Fourteen severe flood alerts warning of a risk to life were in place along the River Thames on Saturday night, with another two issued for the southwest of England, which has borne the brunt of two months of heavy rain.
Friday's violent storm pulled up trees, sent roofs flying off buildings, slammed waves into the coast and opened up a six-metre sink hole in a quiet street in Hemel Hempstead, north of London.
A 49-year-old taxi driver was killed when a building collapsed onto her parked car in the centre of London.
On the English Channel, an 85-year-old man died after high winds sent a "freak wave" smashing through a window of a cruise ship off the coast of north-west France, the ship's operator said.
Some 70,000 French homes were left without power as meteorologists registered winds of up to 150km/h, though most of these had been reconnected by Saturday night.
Meanwhile in Ireland, a 65-year-old man working for telecoms firm Eircom was killed in Cork when he was trying to erect a fallen telephone pole which fell on his head.
