Avalanche forecast for Heiane Wednesday 2019-02-20


Wind slabs are a problem at high elevations. Wet avalanches can release in lower areas in steep terrain. Avoid areas beneath visible gliding cracks, glide avalanches can occur.

New snow (slab avalanches)

Buried weak layer of new snow

Be careful in steep slopes and around terrain traps 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 dangersign.
2 - Medium
Low additional load
Some steep slopes

Wet snow (loose snow avalanches)

Loose snow

Be careful in avalanche release and runout areas. Avoid skiing in terrain traps. Timing is important. Stability decreases when the snow surface gets wet and soft. Wet snow avalanches tend to release spontaneously.
2 - Medium
Spontaneous release
Some steep slopes

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.

Visit www.ut.no for topographic maps online. For slope angle maps, see NGI slope angel maps ("helning" means slope angle).

Modelled snowpack and historic and current weather information can be found on the webpage senorge.no. This site uses information from the weather stations and interpolate values from the stations for gridded maps.
