In sintesi

Cornices remain the primary concern. Solar radiation is a common cornice trigger. Limit your exposure when it's cloudy and completely avoid cornices when it's sunny.

    Small amounts of new snow over old firm layers may produce small loose wet avalanches if the sun comes out in full force.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new reported.

Snowpack Summary

Small amounts of new snow (3-5cm) fell in the past three days. Winds were light to moderate (south through northeast) and may have created small wind slabs on lee features below alpine ridgetops. The new snow will likely be sitting on hard surfaces created by strong winds last week.Elevations below roughly 1300 m are experiencing a daily melt-freeze cycle and the snowpack is likely isothermal. The February crust and facet layer is 70-90 cm deep in the Houston Telkwas sled area and a deep persistent faceted weak layer is still lingering near the bottom of the snowpack in all areas.
