    Results from this layer were seen on March 31st during a earlier warming event after a prolonged cool period.

Weather Forecast

Cloudy conditions will prevail on Saturday with light flurries producing 5-10 cm of new snow.  Light SW winds are forecast with treeline temperature hoovering around -5.  Similar conditions are expected on Sunday with less snow.  The avalanche hazard will rise on Monday with clear skies and double digit temperatures expected.

Snowpack Summary

Mod SW winds forming windslab along alpine ridge tops. A temperature crust can be found on most lower elevation slopes and a sun crust on southerly facing slopes into the alpine. At elevation and if buried by blown snow this will present some avalanche danger. At lower elevation, when intact, is provides stability & support.

Avalanche Summary

No avalanches reported today. A fridge sized chunk of cornice fell on an alpine East facing slope south of the Icefields failed to trigger anything.

Confidence

The weather pattern is stable on Saturday
