Trains have been cancelled, flights delayed and roads blocked as snow sweeps the region.
Between midnight and 10am today Norfolk Police had received 116 weather-related calls.
Out of those calls, seven were because of injuries from road traffic collisions, 14 were damage only incidents and 13 were because of highway obstructions.
Roads
Drivers have been urged to take care on Norfolk's roads, with snow, ice and slush making for hazardous conditions.
Snow fell across most of the region overnight on Monday, with many drivers waking up to snow-covered roads.
By early morning, well-used roads had already turned to slush, which, PC Dan Taylor said, would quickly turn to ice in the cold temperatures.
He said: 'Obvious observation, but the roads are very slippery with the excess snow and slush which is quickly turning to ICE in -6 degrees!
'Please take care on the roads and take it slowly. Already had broken wheels on cars bouncing off kerbs.'
He said the officers in Earlham had already helped push a broken down vehicle off the road in the area.
The ambulance service tweeted at 9.40am to say they had already been called to almost 30 crashes across the region.
There are generally delays across the county, including on major routes such as the A140 from Diss to Norwich.
First Norwich tweeted to say that all its services were running, but that there may be minor delays because of the weather.
Sanders Coaches said all their services were running too, except for the 610 school service to Reepham High. They asked users to be patient, as some may be slightly delayed.
• Emergency services were called to a crash on Byfield Court in Sprowston just before 6.30am on Tuesday morning.
• At about 7am, a car crashed into a central reservation on the southbound A11 at Spooner Row. Emergency services are arriving on scene.
• The B1132 at Kirstead was closed from just after 5.45am and 10am after a BMW car and motorbike crashed. The male motorbike rider was taken to hospital by paramedics.
• The A146 is blocked southbound near Yelverton, causing long delays in both directions.
