Kernpunkte

Freezing levels are forecast to be 3000 m on Tues and Wed. The hazard will rise throughout the day as temperatures warm and the snow becomes moist. More intense solar radiation and a quicker warm up is expected on Wed hence the higher hazard rating.

    Wind slabs can still be initiated around the lees of ridge crests, convex features, and where they sit on a sun crust. These are becoming more isolated as they settle out, but recent activity shows they are still possible to trigger.

    The warm sunny days that we have been having means loose wet slides can be expected on solar aspects in the afternoon. Expect an increase in this activity over the next few days as freezing levels rise. Start and finish your tours early.

  • Deep Persistent Slabs

    The Feb 12 surface hoar is still causing isolated slides. Areas of most concern is terrain with a weak, shallow and rocky snow-pack. In deeper snow-pack areas these layers are not as reactive. Large triggers like cornices may trigger this layer.
