    Up to 30cm of new snow and accompanying wind will create fresh windslabs at higher elevations by Friday. These windslabs will likely settle quickly, due to the warm temperatures. The layer will be most active just after the storm.

    Currently the warm temps encourage the potential for loose and wet avalanches. As the temps cool off to below 0, the danger of loose wet avalanches decreases significantly. Pay attention to temps at your location and anticipate temps far above you.

    The Feb 12 surface hoar is still causing isolated slides. Areas of most concern is terrain with a weak, shallow and rocky snow-pack. In deeper snow-pack areas these layers are not as reactive. Large triggers like cornices may trigger this layer.
