Heavy rain across the North West caused a river in Lancashire to burst its banks, making some parts of the county temporarily inaccessible.
The River Wyre flooded at about 0150 BST. Despite causing a deluge on nearby roads at Hambleton in Poulton-le-Fylde, no homes were damaged.
Officers had to use special 4x4s to drive through the floods and check local communities were safe.
The water has since subsided, a Lancashire Police spokesman confirmed.
"We were lucky," he said, "Hambleton is on a flood plain and there is a caravan park very close to the river.
"Fortunately there were no incidents. The flooding was caused by both the rain and the high tide from the Irish Sea."
He said all roads were now back open.
It comes as heavy floods hit parts of Manchester, with residents in Stockport and Cheadle being the worst affected.
Despite the high rainfall, a hosepipe ban remains across the North West.
Since the ban came into action on 9 July, United Utilities said it had saved 3 billion litres (660 million gallons) but low reservoir levels meant the restrictions must remain over parts of Cumbria, Lancashire, Greater Manchester, Merseyside and Cheshire.
