Torrential rain has brought flooding to the region with a major route impassable and the emergency services urging people to stay off the roads.
It comes after a Met Office yellow weather warning for potential flooding, travel delays and power cuts was issued. The warning is in place from 8am to 5pm today (Sunday, October 6).
Police have also issued warnings to drivers to avoid travel unless essential.
Nathan Clark, from Norfolk Police, said: "Across Norfolk we are experiencing high levels of surface water caused by today's heavy rain.
"This issue is currently particularly acute in the east of the county but all areas are affected.
"Police and partners advise on essential travel only and expect delays whilst we keep the roads as safe possible.
"Conditions are looking to improve into the evening but there are concerns that there will still be lots of surface water making dark conditions particularly difficult."
He added: "There's no threat to life directly from these floods but the issue is the amount of surface water which makes travelling difficult.
"If you're going down the A47 and you find yourself in deep water that's very risky.
"We just need people to take care, particularly on main routes.
"Conditions are going to start improving from now on but the surface water isn't immediately going away and you're going to find a lot of routes are still blocked."
Road traffic control is in place in the following busy routes:
- B1108 junction of the A47, one lane is closed.;
- A143 Beccles Road Gorleston, drain covers are being lifted by loaded drains;
- A47 between Easton and Mattishall lane partially blocked;
- And A1042 Ring Road Thorpe, heavy flood waters preventing movement of traffic.
Norfolk Police tweeted earlier: "Update: Officers and teams from @Highways East are having to close roads due to flooding. The A47 at Easton is currently impassable due to floodwater. If you chose to drive through flooded roads, do you know how deep it becomes?"
Meanwhile, Jason Tooke added: "Felbrigg to Roughton road, impassable in places. Also in Beach Road, Sheringham, a drain has collapsed and there is a lot of water."
Norfolk Special Constabulary also tweeted: "Be careful on the roads today - this is on the ring road in Norwich. A manhole cover has come up due to water pressure and caused damage to a vehicle."
Police are urging motorists to take extra care with standing water in places throughout the county, and to look for vulnerable road-users and be prepared to stop in longer distances.
Dan Holley, from Norwich-based forecaster Weatherquest, said that parts of Norfolk and Suffolk could see 20-30mm of rain and locally 40+mm on Sunday afternoon.
It has also led to delays or cancellations to public transport with communities cut off by flooded roads, and possible power cuts to homes and businesses.
Sarah Goodenough tweeted a photo of her daughters busy journey. She said: "It's taking my daughters hours to get home from Norwich to Carlton Colville and now her bus is filling with water."
Trains between Norwich and Great Yarmouth and Norwich and Lowestoft have been cancelled as the railway line between Brundall and Brundall Gardens has flooded.
Despite replacement buses being ordered, Greater Anglia has said it is yet to receive bus times because of the poor road conditions, and is urging people travelling to wait for the weather to improve.
The railway lines between Norwich and Sheringham have also been affected by the rain with services suspended until further notice.
It comes after flood warnings were issued across the region earlier this week, with homes in parts of the area evacuated.
Norfolk Fire and Rescue Service tweeted: "We are currently inundated with 999 calls regarding widespread flooding. Until further notice, please avoid making 999 calls unless there is a perceived risk to life.
"We recommend to all those at threat from flood water to take precautionary action such as placing towels and turning off the electrical supply. Where possible move valuables upstairs."
Football matches across the county have also been called off, including Sunday league games and a charity match at Bowthorpe's Football Development Centre.
