The snowpack is not likely to get a good freeze overnight, so loose wet avalanches at lower elevations may be a problem in addition to those already identified in the "Avalanche Problem" section.
Confidence
Moderate - Freezing levels are uncertain
Weather Forecast
Tuesday will bring light flurries with accumulations between 5 and 10cm. Alpine temperature will reach a high of 0 °C with freezing levels near 2400m or higher. Ridge-top winds will be from the southwest at 30 km/h gusting to 60 km/h. Long term forecasts have a significant snowstorm arriving on Thursday will accumulations near 25cm. Apparently it's not yet Spring!
Avalanche Summary
A few naturally triggered slabs have been observed in very steep Alpine terrain on solar aspects in the past 24 to 48hrs. These slides were up to size 2.0 and were 50cm deep on average.
Snowpack Summary
Moist snow on all aspects up to 2300m and higher on solar aspects, but moderate winds kept the upper Alpine cooler. Both surface and buried wind slabs are found in wind prone areas in the Alpine and these have been building more into the Treeline with the persistent winds. The March 15th crust down 30 to 50cm on solar aspects has been active in recent days in isolated terrain (see avalanche summary). Cornices are large, are feeling the heat of the April sun, and should be avoided.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Cornices
Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
