Avalanche Forecast

Fair - Intensity of incoming weather is uncertain

An approaching Pacific low will mix up the recent weather pattern starting Thursday evening. Overnight Thursday: Snow amounts 10-15 cm. Ridgetop winds moderate gusting strong from the SE. Freezing levels 1000 m. Friday: Snow amounts 10-20 cm. Ridgetop winds moderate-strong from the SW. Freezing levels 1200 m by the afternoon. Saturday/Sunday: A ridge will persist on Saturday bringing dry conditions and sunshine. Sunday will see dry and mild conditions with increasing high cloud. Freezing levels through the weekend will hover around 1500 m.

Reports od natural glide activity continued through the Skeena corridor. Loose wet avalanches up to size 1.5 continue on steep solar aspects. Explosive testing done within concerning glide slabs produced 2 size 1-2 releases. On Tuesday a large explosive control mission reported 10 size 2-2.5, and 1 size 3 avalanches. Slopes targeted were E-SE, 1500 m and below.

Forecast new snow and wind may build wind slabs on lee slopes, and behind terrain features. Recent spring-like conditions exist through the region. Melt and frozen surfaces continue on all aspects. Slopes that start to become wet, and slushy should be avoided because loose wet avalanches may occur. Lately, a lack of consistent overnight freezing has left the snowpack weak and unconsolidated, even isothermal below 1100 m, although some re-freezing has been reported in some areas. Glide cracks have opened up and pose the threat of large, full-depth releases, especially on steep rocky terrain features at low elevations. Large cornices loom, and ice cliffs pose a threat from above. For more information on Spring Conditions and ways to mitigate risk, please visit the new Forecasters Blog Post.
