Avalanche forecast for Nordenskiöld Land Friday 2017-03-10

3
Considerable
Published:

The snowpack is very unstable. Avoid areas with wind-deposited snow. It is also possible to trigger avalanches in a persistant weak layer in old snow found in bowls and gullies.

Storm slab avlanches

2 - Small
Spontaneous release
Many steep slopes
Possible

Avoid terrain traps and steep slopes until the new snow has stabilized. The avalanche problem is generally widely distributed on any steep slope with deep new snow. Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical sign.

3 - Medium
Low additional load
Some steep slopes
Possible

Avoid skiing in steep terrain (more than 30 degrees) and in runout zones. NB, remote triggering is likely. Make very conservative route choices, especially in unknown terrain, after snowfall and if temperatures rise. Identifying areas where the weak layer is present might be difficult and requires experience. Danger signs are whoumpf-sounds, cracking and recent avalanches. However, absence of signs does not mean it is safe.

For planning your trip and recognizing avalanche terrain, use maps.

Norway has 1:50 000 maps for the whole country. Maps can be bought at bookstores and sports shops, or printed from the net.
