The RAF has been called to Croston to help boost flood defences.
Homes in the village have already been devastated by flood water, with a yellow warning for rain in place for Tuesday evening and Wednesday.
A Royal Air Force Chinook was brought in to help lift sandbags, following a breach of the bank in the River Douglas.
The Ministry of Defence tweeted a picture of a Chinook and said: “A @RoyalAirForce Chinook from @RAF_Odiham has been tasked to lift 1 tonne sandbags in Croston, Lancashire #floods.”
Police said Meadow lane was closed between A59 and Croston, to facilitate work on River Douglas.
A message from Lancashire Police on Twitter said: “There is a flood risk in Croston due to a breach in the bank at the River Douglas just north of Rufford.
“Work is on-going to repair the bank and we are working with @EnvAgency, @ChorleyCouncil & others to support residents in the area.
“The military is also helping to support the repair work at the river bank and the Chinook helicopter will be helping to fly in materials.”
