Extreme weather “Hans”: – Record high water flows

The “Hans” extreme weather has left major devastation, and several people have been evacuated from their homes. But “Han”‘s rampage was not over.

– We’re still inside the incident, and have not seen the final full picture of what will happen in extreme weather “Hans”, Toril Hofshagen told Dagbladet TV.

Hoffshagen works as a special adviser to the Norwegian Directorate of Water Resources and Energy (NVE).

Wednesday morning showed NVE measurements 50 year old flood in places.

Special adviser Hoffsghagen says that water flows are still rising in some of the largest aqueducts, and mentions here both Drammensvassdraget, Gudbrandsdalslågen and Glomma.

He said that a record high water flow has now been measured at a measuring station in Drammenselva.

– Since measurements began in the 1940s such high water flows were measured at gauging stations on the Drammen river, he said.


He said that the NVE is now anxiously awaiting updates from the Meteorological Institute on rainfall into the weekend.

– Will increase

– In some of the smaller streams, the flow may decrease, which is fine, but some of the largest flows will increase towards the weekend, he said.

Hofshagen said those at NVE had been following the situation hour by hour since “Hans” announced his arrival on Monday.

– We are monitoring the situation around the clock, and are having a close and close dialogue with various agencies, said the special adviser.

– In the end, we will see the total consequences of “Hans”, which are still upon us, he added.

According to in-charge meteorologist Susana Reuder at the Meteorological Institute, the worst is over.

– By evening, the situation will calm down, although the consequences in terms of water levels and water flows could last longer, he told Dagbladet.

While there will be periods of rain in some parts of the country, much less rain is expected on Wednesday than has fallen so far this week.

The Meteorological Institute will make a new assessment of extreme weather in the morning, Reuder said.
