Extreme flooding can be expected again: Norwegian water agency

Water levels in some of southern Norway’s water courses are currently at their highest level for over a century.

Flooding of the extending currently seen in the region is “extreme and rare,” according to a hydrologist with the Norwegian Water Resources and Energy Directorate (NVE).

“This is something we will see more of in the future,” NVE climate advisor and hydrologist Hege Hisdal told NRK.

Floods now seem to have peaked in water courses in the south and the water will now gradually recede, although it will take several days for larger rivers to return to normal levels, according to the broadcaster’s report.

“An extreme amount of rain has fallen in a relatively short time. The unusual element was a series of low pressure fronts that followed each other with a lot of rain – it has rained a lot over a large area,” Hisdal said.

Some areas have reported the highest water levels since 1900, writes NRK.

“This is very extreme and quite unusual,” Hisdal said, adding that “it is unfortunate that ongoing climate changes increase the probability of this happening.”

While flooding in the affected area of Norway is a natural phenomenon, NVE has observed a significant increase in both temperature and precipitation since the 1900s, Hisdal told NRK.

As such, more flooding as a result of both rainfall and melting snow is likely, she said.

“It is a result of increases in temperature and precipitation, and although we have a had a lot of big floods, including this one, we know that we can expect this again in the future,” Hisdal said.

Norway to get a taste of summer with 20C days this week

Summer is finally here! Or least it is if you live in southern Norway, where a warm front coming up from Europe will bring t-shirt temperatures of 20C by Thursday, according to forecasts.

Norway to get a taste of summer with 20C days this week

Warm air from southern Europe will combine with a high pressure zone which will bring clear skies and sunshine, with summery weather coming towards the end of the week, Norway’s national weather forecaster Yr has reported. 

“Thursday and Friday especially will be nice,” Ingrid Villa, a meteorologist at the Norwegian Meteorological Institute, told the public broadcaster NRK. “Then we will probably get temperatures of over 20 degrees Celsius in some places.” 

Patches of 20C warmth are expected both in western Norway around Bergen and in Western Norway around Oslo, with the area around Tromsø expected to have slightly cooler weather, although Villa said that “it will absolutely be something like summer there too”. 

The warm sunny weather is, however, expected to pass northern Norway by, with grey overcast skies expected for much of this week. 

But if you think summer has come to Norway to stay, you risk disappointment as much cooler temperatures are expected next week.  

“There’s nothing unusual in getting an early taste of summer in April and the start of May, and then we can quickly go back to cooler more spring-like weather,” Villa said.
