Afternoon temperatures climbing into the low & mid 40s, combined with intense solar radiation will make surface snow wet, loose & unstable. If you notice dripping cornices, the ability to squeeze water out of a handful of snow, or slushy & easily penetrated old surface snow take warning. Rapid warming will change the physical properties of snow, destroying bonds & creating loose-wet avalanche possibilities.
Thursday's new 10cm of wind blown snow has created slabs & scoured other terrain. Friday's winds out of the North & Northeast were uncommon & have loaded South & Southwest aspects. The irregularity of the winds has deposited snow in areas that usually are barren & coincidentally cornices have formed too. The wind slabs have not yet shown much reactiveness.
We received 10cm of new wind-blown snow Thursday night. The winds were strong from the North & Northwest forming slabs & cornices. The new snow was still relatively soft due to warm temperatures & did not produce any alarming results when tested. Moist snow & some water was seen in the first 15cm of the snowpack making penetration with boot & snowmobile easy. Our snowpack is still very thick & overall has a relatively stable characteristic.
A weak disturbance will bring a chance of light showers today through Monday morning with some cooling. Dry and warmer conditions will return through the middle of next week, then a change to a wetter pattern with gusty winds is becoming more likely later in the week through next weekend, with heavy rain and mountain snow possible.
