The probability of a major spring flood is by far the highest in northern Norway, with up to a 95 percent probability. This is what NVE writes in the Spring Flame Analysis released Thursday afternoon.
Large spring floods mean floods at the orange level, which can cause serious damage.
In Trøndelag there are several waterways with up to a 90% probability of flooding, and in southern Norway there is a 75% probability of major flooding at Gudbrandsdalslågen in Losna. The same applies to the upper parts of other water courses.
in eastern Norway.
Meters of snow
The images at the top of the article illustrate the situation in Nordland. The images show the building connected to the pipeline tunnel at the Storelvvatn power plant, operated by the Salten Power Company.
The building was completely buried by snow when crews were on site about 14 days ago. Only the building’s antenna protruded from the snow.
The fact that the building is six meters tall speaks volumes about the colossal amount of snow that will eventually melt. It will cause problems if the heat comes abruptly.
– What we fear most is a higher temperature for a long time and more degrees at night so that the fusion accelerates. So staying away from the water will be a challenge, says Remi Pedersen, department head at Sulitjelmaverket.
40 percent above normal
Right now, there is 40 percent more snow in the area than normal at this time of year. Among other things, Salten Power Company has taken advantage of the two and a half meter Kjelvatnet magazine to be better prepared for what is to come.
Operational engineer Thor Åge Jensen has worked at the Salten Power Association for almost 40 years. He says the situation is rare but not unique.
“We have been dealing with these situations before, but fortunately there are many years between each time,” says Jensen.
Lots of snow both north and south
Northern Norway has received a large amount of snow this winter, but also in the mountainous regions of southern Norway there is a lot of snow. In a snow report dated May 7, NVE wrote that the snow melting in some parts of the mountains in southern Norway has just started. Elsewhere, it hasn’t been seen to have reduced snowfall at all.
The season at Sognefjellet showed that there has been more snow in recent weeks. In Sjusjøen there was twice as much snow as normal.
The trend is the same in central Norway, and snowfall is so extreme in northern Norway that it has trouble measuring itself. The measuring stations have simply snowed.
You have to go back to 1997 to find a snowier winter in Troms and Finnmark.
