Kernpunkte

Overnight freezing levels will be high, allowing warm temperatures to saturate the front range snowpack. Watch out for wet loose avalanches at tree line and below east of the divide.

    If the snowpack dose not freeze overnight the hazard will be significantly higher.

    As temperatures warm, the basal facets may become a player again, especially in the relatively shallow front ranges. Consider overhead hazard, the consequence of a small avalanche triggering a deeper slab, and stick to deep well supported terrain.

Weather Forecast

Thursday night: Freezing level 1600m with 1- 2 mm of precipitation.

Friday: Mainly Cloudy. Freezing level 1800m. Moderate to Strong SW wind. 1-2 mm of precipitation.

Saturday: A mix of sun and cloud with isolated flurries. Freezing level 1400m. Wind SW.

Sunday: Cloudy.1-5mm of precipitation. Freezing level 1400m.

Snowpack Summary

Strong to extreme SW winds have formed wind slabs at all elevations. These windslabs have the potential to trigger weak layers deep in the snowpack during this warm period. The base of the snowpack consists of crusts and weak facets formed early in the season. The snowpack east of the divide is significantly shallower and inherently weaker.

Avalanche Summary

Public report of Natural Sz 1-1.5 loose wet avalanche activity at Bertha Lake on Thursday January 23.

Confidence

Freezing levels are uncertain
