Areas of south-east Norway were evacuated and residents braced for more landslides and flooding as rivers swollen by days of heavy rain carried large amounts of water through the mountainous landscape on Thursday.
People living near waterways were moved to safety, taking their belongings from their homes and moving their cars to higher ground, while helicopters were on standby to help move people out of remote areas.
The Begna river, which runs through the town of Honefossen, had burst its banks and because of fear of landslides, the municipality announced an evacuation.
The Red Cross and the civil defence sent around 200 people to a nearby hotel by bus.
one Velo, a local resident, wrote online: “Darn, this is bad. I don’t think everyone understands how much water we are talking about. The peak is far from being reached. More is to come when the locks are opened.”
Authorities did not provide a nationwide count of evacuees, but according to Norwegian broadcaster NRK, the figure was up to at least 4,000.
The initial damage estimate was at 1 billion kroner (roughly £76 million), according to the Norwegian Natural Perils Pool, an insurance regulator.
“We expect far more damage reports in the future,” spokeswoman Stine Neverdal said, stressing the figures were preliminary.
Although the rain has mostly stopped, authorities say the flooding is expected to continue until at least Friday. Major roads and train lines are likely to be closed for days.
