The water is rising in Nesbyen, and highway 7 is closed between Bromma and Gol, writes NTB.
Detour takes place via E16, informs State Highways Authority.
Possible evacuation
The large bodies of water will move downwards towards Drammen. On Sunday, NVE sent out a red danger warning to several municipalities located around the Drammensvassdraget.

– There is great uncertainty in the forecasts, but the water level at the Mjøndalen bridge will probably be higher than it was after the extreme weather “Hans” earlier in August, Drammen municipality writes in a press release.
The flood protection that has been set up along the Drammenselva is designed to handle a flood level of 3.5 meters above the water level in the fjord, but the water level is expected to reach this level. In the worst case, this means that the flood protection is not sufficient to prevent the water from flowing into residential areas, writes the municipality.
Mayor Monica Myrvold Berg says the situation is very demanding, and that it is important that everyone understands the seriousness of such large amounts of water.
– It is important that no one underestimates the risk of flooding and does what they can to secure their own values and themselves. Hopefully the flood protection the municipality has put in place will work well this time too. But we cannot ignore the fact that the water masses rise above the level that the flood protection is able to handle, says Berg.
Notifies evacuation
Among other things, Ringerike municipality further north on Sunday again warned about potential evacuations of areas around the rivers in Hønefoss.
Close to 1,800 residents were evacuated earlier in August as a result of the extreme weather “Hans”.

– It is difficult to say how it will develop, says Nesbyen mayor Tore Haraldset Hallingdølen.
To Dagbladet, the mayor says that there are now 30 people who have evacuated themselves.
– The water is not rising much now, but it has been reported that it will rise more during the evening. Now water has started to flow into the cellars, but they were already damaged, says Haraldset to Dagbladet at 7.30pm on Sunday evening.
Many of the houses that are affected are the same ones that were affected by the extreme weather “Hans”.
Highway 7: Flooding
– Can go higher than under “Hans”
The Drammensvassdraget is hardest hit by the large amounts of rainfall, informs hydrologist at the NVE flood warning, Elin Langsholt, to Dagbladet on Sunday evening.
– In Ringerike, Tyrifjorden and Randsfjorden, it is rising, and it will continue to do so. It will culminate on Monday or Tuesday, it seems, since no rain has been reported, says Langsholt.
The water will flow down towards Hokksund and Mjøndalen, where there is an orange flood warning.
Langsholt says that the water level in the Drammensvassdraget can go higher than during the extreme weather “Hans”.
The water is also rising in Mjøsa and Øyeren, but here it is not expected that the water will rise quite as high as during the previous extreme weather.

Evacuees in Ål can move home
In the neighboring municipality of Ål, the evacuees have been allowed to move back again after the geologists on Sunday evening gave the green light, the mayor told NRK.
– The area has been checked by a geologist, says Ål mayor Solveig Vestenfor NRK.
She says to Hallingdølen that there is no danger of new landslides. The evacuees are therefore allowed to return home.
– But some take up the offer to spend the night at the hotel until tomorrow, she says.
Around 100 people were evacuated in Ål municipality in Hallingdal on Sunday due to the risk of landslides.
On Saturday, the municipality warned that the rain could create challenges, especially in areas where landslides occurred earlier this month, writes Hallingdølen.
