Natural avalanches are possible, human-triggered avalanches are likely. Small avalanches in many areas, or large avalanches in specific areas, or very large avalanches in isolated areas.
Things are heating up and spring is in the air, but there are still problems lurking deeper in the snowpack. Rising temperatures could make these older layers more reactive for a time, and smaller surface slides could also set them off. Be aware, take the right equipment and learn the skills.

Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.
Riders' weight, rapid warming or a smaller surface avalanche could cause weak layers deep in the snowpack to fail. This could create a very large avalanche event, so keep this in mind when planning your route. Will you be in a place of relative safety if this happens? If not, is that a risk you should you take? Whumphing and cracking are signs you are on unstable snow. Remember you could even set off this problem from a distance or from a flat area.

There could be some areas of windslab near ridges, after recent W, SW and NW winds. Watch out for obvious build-ups of snow, signs of previous wind on the snow surface, and shooting cracks. Keep in mind that a small windslab avalanche could start a bigger persistent slab avalanche.

As the sun gets stronger and the air temperature increases, surface snow will become unstable. Even a small slide could trigger a deeper slab. These wet avalanches could also behave like slabs, making them larger and more dangerous.

Recent avalanches:
Snowpack: Periods of moderate to strong NW, W and SW winds in the days following the last big snow storm (which ended on on Feb 21st) have resulted in areas of windslab near ridges. There is a weak interface between the snow that fell in the last storm and the previous snow layers - this can be found at most elevations and aspects. There are also weak and unstable layers lower in the snowpack and near ground, which now have a considerable weight on them and can produce large avalanches when they fail.
Mostly fine for the next few days with light to moderate N and NW winds. Freezing level 1250 Wednesday, increasing to 3200m by Saturday.
