Standing water in some areas of Preston has caused delays throughout the day.
The Met Office had issued a yellow rain warning for Lancashire as rain continued to fall throughout the night and into Friday morning.
Flyde Road and Aqueduct Street have both had slow moving traffic throughout the day due to flooding.
Preston is looking to mitigate flooding in the area with a series of flood scheme drop-in meetings throughout October, hosted by the Environment Agency.
The Environment Agency is working with Lancashire County Council to improve the Preston and South Ribble flood risk management scheme.
The current proposed scheme is likely to cost in the region of £45 million.
The flood defences will include: flood walls, localised use of glass panels and embankments.
The project launched in March 2019 although construction is not expected to commence until 2021.
