The formation of strong surface crusts has effectively put a lid on avalanche concerns in the region. Expect rugged travel conditions.
A helicopter flight on Wednesday allowed for wider observation of the natural wet avalanche cycle that occurred in the region over the few days prior. Avalanches up to size 2.5 (large) were observed on all aspects and all elevations, with larger slides running surprisingly far given the low snow coverage in many runout zones.
The upper snowpack has been heavily saturated by recent rain. Moist or wet snow now extends down roughly 30 cm from the surface and a surface crust has begun to form. This crust will extend to lower elevations and become increasingly thick and supportive in the coming days.
The mid and lower snowpack contains several old crusts but remain generally well-bonded and strong.
Snow depths decreased significantly as a result of the rain, particularly below treeline where many areas are again below threshold depth for avalanches. Where coverage remains, it has become patchy and disconnected at all elevations and aspects.
