The RAC is warning the knock-on effects from Storm Dennis "will be felt by drivers for some time yet".
Spokesman Rod Dennis said: "Aside from the current road closures, with so many flood warnings still in force, there is a very real risk more roads will be affected by flooding over the next few days.
"It's vital drivers take no risks - if they can't be sure the water is shallow enough to safely drive through, turning around and finding another route is always the best option."
The Environment Agency for England has removed flood warnings for the Wainfleet area in Lincolnshire.
"Levels are dropping but we're continuing to monitor the situation," the agency said.
With more rain predicted, it's worth keeping an eye on the various flood alerts and warnings in place across the country on the Environment Agency website here.

Welsh First Minister Mark Drakeford has defended his government's investment into flood defences following widespread damage caused by Storm Dennis.
Mr Drakeford visited several homes on Monday in one of South Wales' worst hit-communities, Oxford Street in Nantgarw, which saw heavy flooding on the weekend leaving properties and businesses ruined.
The Welsh Labour leader tells the PA News agency: "There has been major investment in flood defences, and the impact of the events over the weekend would've been even worse if it weren't for the investment that had already been made.
"Of course there is more to do. We have a £350m investment programme over this Assembly term in flood and coastal flooding programmes.
"The impact of global warming is real and there for anyone to see, the science tells us we will have to face in greater frequency these intense weather events in future."
We reported earlier how two new severe weather warnings - meaning danger to life - had been issued for Upton upon Severn in Worcestershire.
BBC reporter Phil Mackie, who is in Upton, has captured a photograph that shows just how swollen the river there has become.

Labour MP Rachael Maskell has called for improved flood defences for the city.
She says: "There's a lot of frustration felt. There's been a lot of talk and lots of surveys done, but we need action.
"Certainly I'll be pushing the government when Parliament returns to get on and get proposed schemes in place.
"In the Clemonthorpe area of York, we should have a barrier across the road not sandbags. But also further down the river, individual properties need that resilience so they don't flood."
More than 200 flood warnings are in place across the UK, including six severe - or "danger to life" - warnings for the rivers Lugg, Severn and Wye.
There are three for the River Severn - two of those are in the town of Upton upon Severn, in Worcestershire, and one in Uckinghall in Gloucestershire.
The River Wye's two warnings are for Hereford and Hampton Bishop, where there is also a severe warning for the River Lugg.

The village of Nantgarw near Cardiff has been badly affected.
Ian Best lives there with his family and told BBC Radio 5 Live how he raised the alarm with his neighbours when he realised the water was coming in.
"It was awful," he said. "I had my daughter crying upstairs. You don't know how high it's going to come, and when we could see the cars floating down the road... it just happened so quickly.
"We had a phone call at 4am - by 4.30 we were underwater."
Ian has already taken up his kitchen floor.
"I spoke to the insurers," he said. "As long as we take plenty of photos we can take it up and start drying the rooms out - but the floor underneath doesn't look too good."Copyright: BBC
"We've got another room we can't get into at the moment because the furniture's floated and I can't open the door so I'll have to take the door frame off.
"Devastated doesn't come close to it. We're looking at tens of thousands [of pounds]."Copyright: BBC
Labour leadership candidate Sir Keir Starmer says it's an "appalling decision" not to hold a meeting of the government's emergency committee, Cobra, to discuss the severe flooding.
He tweeted: "The recent flooding is a stark reminder that the government is not doing enough to get to grips with the climate crisis.
"Ministers should be taking a lead on this situation, not ducking their responsibilities."
Prime Minister Boris Johnson is not expected to visit any flood-hit areas on Monday, but Downing Street said he was being kept updated about events.
The PM made visits to flood-hit Matlock in Derbyshire and Fishlake, near Doncaster, during the election campaign in November.
Environment Agency chief executive James Bevan says some communities "remain at risk as the larger rivers continue to rise".
He tweeted to say the agency will "remain on the ground and in incident rooms 24/7 to get people back to their homes and businesses" as soon as possible.

5 Live's Rory Carson has been speaking to people in Pontypridd, where he says the clean up operation is well under way.
Geraint Day is chair of Clwb Y Bont - a club that promotes Welsh language and culture in the centre of the town.
"Sunday night was the time it was really bad," he said, "looking in the function room now it's covered with mud. The ceiling has stayed up but the rest of the club is a complete mess, the bar, everything is covered in mud... there's not a hope of saving anything electrical.
"Anything with soft furnishing is going to be covered with flood mud and contaminated with sewage as well."Copyright: BBC
Mr Day said he has "no idea" how much it will cost to repair.
"Because it's an area of high risk flooding, despite the flood walls, we can't get insurance for flood protection so we'll have to do it ourselves."
He said they're appealing for donations, and relying on volunteers: "We'll pull together and reopen I'm sure."
Part of Aberdare in Rhondda Cynon Taff was turned into a lake after about a month's worth of rain fell in Wales in just 48 hours.
Natural Resources Wales, which shot the footage below, said the level of rain was "unprecedented" as railway lines were turned into canals, and roads into rivers.
Some people who have been trapped in their homes in Nottingham since Saturday night say they believe it is down to a design fault with a £430,000 flood alleviation scheme.
The flood alleviation scheme for Thoresby Dale in Hucknall was completed by Nottinghamshire County Council less than two years ago.
People in four houses on Thoresby Dale have not been able to leave at all since Storm Dennis hit over the weekend, because opening their gates would cause water to flood their homes.
Others have not been able to drive their cars down the street. The council has been asked to comment.
"We are now over 40 hours in and water is still coming up from the system that should be taking flood water away," said Ian Stevens, who is among the trapped residents. Read more here.
