A major incident has been declared in Norfolk after large parts of the county suffered serious flooding.

Firefighters dealt with more than 300 calls in 12 hours overnight.

About 50 crews were called out across the county.

Long Stratton is particularly badly hit, with video captured by staff at the Netherton Steakhouse showing cars having to crawl through standing water on the A140.

Police also said there was flooding on the same road at Pulham Market, while the conditions had also led to a car going into a hedge further south on the A140 at Dickleburgh.

People have been told to only travel today if absolutely necessary.

The A47 is shut between Easton and Honingham and is likely to be closed for some time.

The A11 is closed at the A1075 junction at Thetford.

There are no trains between Norwich and Diss.

A three-car crash on the A11 at Spooner Row near Wymondham saw one southbound lane closed while the vehicles were recovered.

Heavy flooding also closed New Road and Mill Road in Belton, while the torrential rain was causing delays on the A143 near Scole and the A146 between Loddon and Gillingham.

Konectbuses said there is major disruption this morning and passengers were told to expect severe delays to all services, particularly routes 1, 4, 3, 6, 8, 11, 84.

In an update on Twitter, Norfolk Police said: "We are continuing to deal with flooding on roads across the county, working alongside @highwaysEAST and @Norfolkfire where required.

"Slow down, drive to the conditions, do you know how deep the floodwater is?"

Meanwhile, more than 600 people in areas such as Norwich, Hethersett and Wroxham were without power at the end of a busy day for UK Power Networks engineers.

Dan Holley, of Norwich-based Weatherquest, warned that, despite the level of disruption already caused, there was "several more hours of rain to come".

He added: "Since midnight, Tibenham Airfield has recorded 33mm, this falling on already saturated ground."

There are flood alerts in place on the tidal River Yare from Thorpe St Andrew to Breydon Water, the River Waveney from Diss and the River Dove to Ellingham, including Bungay, as well as at the Welney Causeway near Downham Market.

In Suffolk, there is a more serious flood warning in place for the Chediston watercourse at Halesworth.

In a statement on their website, Anglian Water said: "Due to the wet weather we are currently helping a lot of customers.

"Our top priority is to prevent flooding to people's homes, and we will deal with those issues first. Because of that, it may take us a little longer than usual to deal with problems affecting wastewater systems and sewers, but please rest assured we will help all customers as soon as we can.

"Some of the problems we are dealing with are caused by the huge amount of rain that has fallen recently, meaning the ground is already saturated and a lot of flood water is getting into our sewers. This means water doesn't drain away as quickly as it usually would.

"These problems often fix themselves, though, when the rain stops."
