The 10 day outlook for the forecast region is showing snow starting Thursday ending Saturday with acuminated values of 10-20cm. This is followed by clearing skies and a decrease in temperatures for the remainder of the week.
Snowpack Summary
A broad contrast in conditions exist in the forecast region. While the valley bottom is still green, a winter snowpack is starting to develop at higher elevations. You can expect to find wind slabs, faceted layers and highly variable condition in the alpine. Upper elevation gulleys could be holding over 100cm creating a serious avalanche threat.
Avalanche Summary
Natural avalanche activity has been observed through the forecast region. In most observations avalanches have released from high alpine terrain with an increase in activity as high wind values rip through the valley.
Confidence
Avalanche Problems
Wind Slabs
Strong winds have transported the early season snow, creating wind slabs at upper elevations. While traveling in avalanche terrain be weary of active snow transport and high wind values as this will likely spark an increase in avalanche activity.
- Be careful around wind loaded areas near ridge crests, cross loaded gullies and roll-overs.
Aspects: All aspects.
