You can trigger a slab avalanche on a wind-drifted slope at upper elevations. On northerly or easterly-facing terrain, one of these might break deeper into buried weak layers and grow into a destructive slide. Lower-angled slopes in wind-sheltered terrain offer safer conditions. Move away from steep slopes with wet snow later in the day.
On March 7th, a backcountry skier was caught and killed in an avalanche near Vail Pass. The avalanche released on a northeast-facing slope near treeline, about 2 to 3 feet deep. Our deepest condolences to the deceased skier's family, friends, and community. You can read the preliminary accident report here.
