Debris avalanches, debris flows and slushflows warning yellow level for Troms and Finnmark and parts of Nordland

2

Yellow level

Published: Valid: from 06.06.2020 07:00 to 07.06.2020 06:59
Next forecast before:
  • Danger decrease: Monday morning 15. Jun. 2020
  • Height: 0 - 1800 moh

Consequence

Some landslides are expected. A few large events may occur. Exposed roads may be closed. Debris avalanches/shallow slides: Soil slides and rapid movement of saturated soil in steep terrain. Debris flows: A "flood" of water, soil and rocks in steep creeks. Surface runoff in steep terrain can cause streams to change regular flow patterns. Slushflows: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes.

Advice

Keep yourself updated about the development of the weather, the landslide and flood situation. Keep away from steep slopes, as well as streams and rivers with high discharge.

Description

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.
