Low - Due to the number of field observations

Avalanche Summary

There have been no recent reports of avalanche activity. That being said there is little to no information being passed on from the region recently. Exposure to large overhanging cornices remains a significant concern. As the sun comes out over the weekend I would expect see cornices weaken and loose snow avalanches run from steep sun exposed slopes during the warmest parts of the day.

Snowpack Summary

New snow falling last week has been redistributed by south and east wind at upper elevations. This is likely sitting on a hard wind crust in exposed alpine areas and sun crust on aspects facing the sun. Elevations below 1300m roughly are experiencing a daily melt-freeze cycle and the snowpack is likely moist or wet throughout its entire thickness. A persistent weak layer buried late February may be found down approximately 70-100cm and a deep persistent weak layer is still lingering near the bottom of the snowpack in all areas.
