Warm temperatures and sunshine continue to create slushy surface snow and potential for heavy, wet avalanches.
Potential for wet avalanche activity (slab and loose) increases as temperatures rise, but concern is greatest on steep, sun affected slopes. Avalanches may initiate easily on the smooth crust below.
Small loose wet avalanche activity was reported on Friday and Saturday. We are still awaiting observations but expect that wet avalanche activity intensified during the rapid warming period on Sunday afternoon.
Around 30 cm of recent snow is becoming moist or wet in the warm temperatures and sunshine. It is reportedly bonding well to an underlying crust. Dry and even wind affected snow may be found on shady aspects in the alpine.
At low elevations the snowpack is melting out with each day of warm weather.
