UPDATE: Flood alerts issued for southern and eastern Norway

Melting snow and rising temperatures will likely lead to spring floods in several places in Norway this week, both in the south and the north.

The temperatures are rising in Norway, and with the heat comes snowmelt and spring floods.

A large number of flood danger warnings have been issued, and the Norwegian Water Resources and Energy Directorate (NVE) asks people to follow the news and secure loose items.

The flood danger has already reached the orange level (i.e., considerable danger) in the Trysilvassdraget, Altaelva, and Krøderen areas. 

They expect the flood danger to reach the orange level in several places during the next week.

‘Important to follow updates online’

“The most important thing people can do is follow updates on varsom.no. We regularly update the site with new information. Right now, the greatest danger is present in parts of Troms og Finnmark,” hydrologist Anne Fleig at the NVE told Norwegian newswire NTB.

The danger warning for Troms and Finnmark is expected to remain in place up to and including Wednesday.

Fleig further said that the melting snow was a major driver of flooding risk.

More precipitation is expected on Tuesday, and the meteorologist emphasized that the danger is greatest when it rains.

The NVE has also sent out a number of danger warnings at the yellow level. However, Fleig says that some warnings are more uncertain than others and that it is, therefore, important to follow updated information.

Weather alert for torrential rain and thunderstorms issued in Norway

More heavy rain is expected in eastern parts of Norway on Tuesday evening. Around 12 millimetres are expected, and a yellow weather warning has been issued.

On Monday, parts of eastern Norway received 42.7 millimetres of rain, the monthly average for May being 60 millimetres.

The heavy rain flooded streets and some basements in parts of the capital.

The public has asked to avoid swimming in Oslo’s harbour areas after the rain due to the presence of intestinal bacteria.

A yellow warning has also been issued for lighting in eastern Norway. The public has been asked to unplug appliances and avoid open plains and large trees. Swimming has also been discouraged.

Around 30,000 and 40,000 lightning strikes were registered in Norway over the past 24 hours.

During a yellow weather warning, the public is asked to “be aware” of “challenging situations”.
