The Internet can be affected
Vågane explains that the varying weather that is experienced in østafjells is due to the warm weather that is currently being experienced.
– The hot temperature leads to unstable air, which in turn can lead to heavy showers, hailstorms and thunder. We expect that different areas of østafjells will be affected by these.
YR’s website states that there is a risk of damage to object (s) as a result of lightning. The power supply and TV / internet may be affected.
