An RAF Chinook helicopter was heading back to Croston this afternoon to continue repairs to vital flood defences.
A breach in the earth banking alongside the River Douglas led to the village being inundated on Boxing Day.
Yesterday a Chinook from Hampshire, piloted by Ft Lt Chris Dodd from Euxton near Chorley, dropped huge sandbags into the gap in a bid to prevent the river bursting through again with Storm Frank threatening the region today.
Another Chinook from the same base was due in Croston at lunchtime today to continue the work as residents battened down the hatches in case of a new flood.
Three “severe” flood warnings from the Enviornment Agency remained in place, although the signs were looking more positive as the storm appeared to be passing to the north of the county.
A Lancashire County Council spokesman said: “The worst case scenario is that there may be an overtop of 100mm at the bottom end of the breach later this afternoon.
“But if this does occur the land around the breach will refill for a period of around an hour either side of high tide – expected between 2pm and 3pm today.
“As water levels have reduced significantly and pumping continues throughout the coming days to remove water from this area, risk to further flooding to properties in Croston remains low.”
Residents are being urged to remain prepared in case of further flooding, although the forecast in the area for the next 48 hours is for predominantly dry weather with temperatures dropping.
