Avalanche activity is more likely as sun and rising temperatures affect the snowpack.
Minimize your exposure to cornices, and steep south facing slopes in the heat of the day.
Recent winds have varied, watch for small but reactive wind slabs on all aspects. Greatest reactivity is expected where slabs form over a crust.
Cornice falls are unpredictable and can trigger large avalanches on deeply buried weak layers. Avoid exposure to large cornices, on ridgelines and on the slopes below.
Rising temperatures and strong sunshine will increase potential for wet avalanches. Warming will be most intense on steep south facing slopes, especially near rocks.
No new avalanches were reported on Tuesday.
Earlier in the week, natural wind slabs were reported from north and east facing alpine slopes. Several were cornice triggered, stepping down to buried weak layers.
Small loose wet avalanches continue on steep south-facing slopes in the afternoon.
Expect to find dry snow on high north-facing slopes, crusty or moist snow at lower elevations and on sun affected slopes, and firm, wind-affected snow in exposed terrain.
The mid to lower snowpack remains generally well-settled and strong, with old weak layers now buried 50 to 200 cm deep. Large triggers, such as cornice collapses still have the potential to trigger these deeper layers, particularly on high, shaded north aspects.
Below treeline slopes are melting fast and generally below threshold for avalanche activity. Watch for stumps, rocks and open creeks.
