Debris avalanches, debris flows and slush slides warning orange level for parts of Nordland and parts of Troms

3

Orange level

Published: Valid: from 19.03.2022 07:00 to 20.03.2022 06:59
Next forecast before:
  • Danger ongoing: Saturday early morning 19. Mar. 2022

Consequence

Landslides are expected, some with considerable consequences. Large slides may reach settlements, roads and railways.

Advice

Keep water paths and culverts free of snow, ice, gravel, waste, twigs and leaves. Clogged waterways with dammed water may cause landslides. Municipalities, Counties and other emergency operators should continuously evaluate the need for preparedness and prevention measures.

Description

Landslides are expected, some with considerable consequences. Large slides may reach settlements, roads and railways. Heavy rain is expected. Relatively high temperatures and windy conditions causes significant snowmelting. Steep slopes, as well as streams and rivers with high discharge, are particularly exposed. Risk of slushflows is especially high in areas with more than 50 cm snow. The snow may in some places be fully water-saturated. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows.
