This is the dramatic moment sea water reached a gym as a fierce storm battered Morecambe Bay on Thursday.
At one point cars were left floating with 25 people trapped inside VVV Health and Leisure Club on Marine Road East.
Those inside had to place sandbags at the doors as water got into the pool and spin room.
Liverpool Coastguard said they had been busy around the Lancashire coast throughout the day.
Lancashire Fire and Rescue service said they had been called to 28 weather-related incidents, including collapsed structures, traffic incidents, flooding and one fire.
