Debris avalanches/shallow slides warning yellow level for deler av Innlandet og Viken

Oppdatert informasjon -

Varsel for deler av Innlandet og Viken er oppgradert til oransje nivå for tirsdag. Dette grunnet lokalt mye nedbør og generelt høy vannmetning i bakken.

Consequence

Landslides may be expected. Exposed railways and roads may be closed. Along the watercourses in the flood areas high discharge can lead to erosion of masses at the foot of slopes. Rapid decline of water levels after flood can also cause local landslides.

Advice

Keep away from steep slopes, as well as streams and rivers with high discharge. River erosion may trigger minor soil slips, which again may reduce the soil stability along the river. Be aware of such soil slips in areas mapped with quick clay, and areas with marine deposits. If such observations are made, do not hesitate to alert responsible municipal emergency staff at the local kommune.

Description
