The Suffolk Resilience Forum has formally called an end to the major incident that was declared in response to the tidal surge.
King's Lynn was one of the first places hit by yesterday's tidal surge, where the North Sea topped the town's flood defences.
The beach huts on Southwold seafront were damaged large waves during last night's storm.
Thousands of people across Norfolk have been advised that it is now safe to return to their homes.
Around 10,000 properties were visited yesterday, with many residents encouraged to evacuate.
However, following consultation with the Environment Agency, all partner agencies have now agreed that a phased return can begin.
Thousands of fish have been evacuated from a sea life sanctuary in Hunstanton in Norfolk following last night's flooding.
The Environment Agency says the greatest danger has now passed following the tidal surges in the last 24 hours.
Officials said in some places tidal heights were as high or higher than those seen during the 1953 floods but improved coastal defences meant the damage was far less significant.
Surges later today will be up to half a metre lower and there are still flood warnings in place, but there are no longer severe warnings in East Anglia.
Toby Wilson from the Environment Agency paid tribute to the job done by flood defences along the coast:
"Clearly for many communities who were impacted overnight it's been a devastating event.
"Our thoughts go out to those who have been evacuated, whose homes have been flooded, but it didn't have the impact of 1953 and I think that's a testament to the investment in flood defences."
It was busy night for Norfolk's emergency services, after a tidal surge battered the county's coastline. Here are the key facts and figures from the last 24 hours:
- Norfolk Fire and Rescue service attended 116 incidents including nine flood rescues.
- More than 600 people made use of the various rest centres around the county.
- 10,000 properties were visited with residents advised to evacuate.
- Highways assisted with 21 fallen trees and 11 road closures.
Several homes by the sea in Hemsby in Norfolk have been destroyed by large waves.
The Environment Agency has reduced the number of severe flood alerts to 19. There are now far fewer warnings in the Anglian region and none in the North-East.
