Points saillants

A strong overnight freeze is keeping the surface crust intact throughout the day. All freeze, no melt.

Be prepared for rugged travel (especially at lower elevations), with creeks opening up and variable surface conditions.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

A natural size 2 glide slab avalanche was observed in the highway corridor on Friday.

A few natural wet loose avalanches up to size 2 were observed in the forecast area last week while freezing levels hovered around 3000m.

Snowpack Summary

Cooler temps will keep a surface crust intact on all but lower elevation solar aspects.

The April 13th crust is down 15-30cm. The robust March 21 crust is down 40-80cms. These crusts could provide sliding layers when/if things warm up dramatically.

Weather Summary

High pressure creating a stable weather pattern with continued overnight freeze/ recovery.

Terrain and Travel Advice

  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
