The Environment Agency today warned more flooding was possible in the South East as up to an inch of rain threatened to fall on saturated river catchments.
A week after Sussex was hit by the worst flooding for 40 years, rivers that burst their banks had receded but surrounding flood plains remained full.
Forecasters from the Press Association's independent weather centre predicted rain currently over France could sweep across the South East by midnight.
The Environment Agency said the downpours could bring some localised flooding and urged homeowners to stay vigilant.
Flood watch warnings were issued for the River Ouse between Barcombe and Lewes, the River Uck and the River Cuckmere.
An agency spokesman said: "We will be keeping a very close watch on weather patterns.
"We would urge those living close to rivers covered by flood watches to be on their guard and be prepared for flooding, which is a possibility."
