Norwegian authorities have issued a level 4 avalanche warning for multiple regions in Southern Norway, valid from Thursday. This warning is due to a combination of high precipitation and mild weather, which can cause avalanches to be triggered naturally. The Norwegian Water Resources and Energy Directorate (NVE) urges the public to avoid avalanche terrain and maintain distance from steep mountain sides. Regions such as Jotunheimen and Indre Sogn are particularly highlighted in the alert, as they are expected to experience wet and dry slab avalanches that could impact infrastructure or populated areas.

In addition to the regions already under warning, the avalanche danger is significant across the rest of the country and may increase in the coming days due to the ongoing mild weather. As this weather pattern continues to spread, more regions are likely to escalate to a level 4 warning, including substantial parts of the Vestlandet. Emma Julseth Barfod, a group leader in NVE's avalanche warning team, commented on the increase of danger and the need for caution among outdoor enthusiasts and residents in these areas.

As snowfall and rain persist, the risk of avalanches is expected to remain high, prompting officials to advise against engaging in activities in snow-covered mountainous terrain. The public is being reminded of the dangers associated with avalanche conditions and the importance of staying informed through official channels such as Varsom.no for the latest updates on avalanche dangers, especially as conditions may rapidly change with the weather fluctuations according to forecasts.
