Cornice Fall, Loose Wet
Travel & Terrain Advice
Use caution on steep solar aspects in the alpine and upper treeline. Avoid cornices and the slopes below them. Use sunscreen.
No new avalanches observed or reported. Some minor loose wet activity from steep rocky terrain.
Cornices will continue to weaken with warm temperatures and solar input. Largest hazard in the alpine and upper treeline on NW through NE aspects. These failures could possibly produce large (size 2) avalanches, or may trigger deeper layers on slopes below.
Steep solar aspects at treeline and above will likely produce small (size 1) loose wet avalanches.
Little change in the snow pack. All aspects becoming moist in the afternoon above treeline while some surface hoar lingers below treeline in protected terrain. Upper snow pack dense and settling on top of a thick old buried crust. Well settled and dense below.
|Surface||Moist above treeline and some surface hoar below treeline.|
|Upper||Well settled old storm snow on a thick old crust.|
|Lower||Well settled and dense.|
Inverted with light winds and temperatures approaching double digits in the afternoon in the alpine. Fog bands at below treeline elevations.
MONDAY - No precipitation, freezing levels to 2500 m. Light variable winds.
TUESDAY - No precipitation, freezing levels to 2500 m. Light NE to SE winds.
WEDNESDAY - 0-3 mm of precipitation, freezing levels to 2200. Light SE - S winds.
