Debris avalanches and debris flows warning yellow level for eastern and central parts of Vestlandet

2

Yellow level

Published: Valid: from 11.09.2018 07:00 to 12.09.2018 06:59
Next forecast before:
  • Danger ongoing: Tuesday morning 11. Sep. 2018
  • Danger decrease: Wednesday evening 12. Sep. 2018

Consequence

Some landslides are expected. A few large events may occur. Exposed railways and roads may be closed. Debris avalanches/shallow slides: Soil slides and rapid movement of saturated soil in steep terrain. Debris floods: A "flood" of water, soil and rocks in steep creeks. Surface runoff in steep terrain can cause streams to change regular flow patterns. Increasing water flow in streams may cause local flooding and ice jam flooding.

Advice

Stay updated on the latest weather developement and hydrological situation. Follow the weather forecast and radar at yr.no, and updates on varsom.no. Keep away from steep slopes, as well as streams and rivers with high discharge. Cleaning of drainage paths and culverts are recommended. Keep water paths and culverts free from snow, ice, sediments, waste, twigs and leaves.

Description

Steep slopes, as well as streams and river with high discharge are particularly exposed. Debris flows may reach the valley bottom even if they are triggered high in the terrain.
