Southern Britain is braced for a "wild Wednesday" of storms and rising water levels, with no prospect of an end to the misery in sight.
The Government's Cobra emergency committee will convene again this morning after David Cameron pledged that "money is no object" in providing relief to communities devastated by floods.
But the Prime Minister also warned that "things may get worse before they get better", with hundreds of flood warnings and alerts still in force.
As if to underline his words, within hours 1,700 homes in the Thameside village of Datchet suffered power cuts, leaving engineers scarmbling to fix the fault.
The Environment Agency (EA) has said rises in the level of the River Thames are among the biggest threat over coming days.
Windsor and Maidenhead, Berkshire, as well as parts of Surrey, are now considered at risk, on top of the 1,000 properties reported as flooded over the past week.
