Regions: Kananaskis.

We are expecting some new snow this week which will bury a few layers in the snowpack that will likely become persistent problems.

Confidence

Moderate - Intensity of incoming weather systems is uncertain on Tuesday

Weather Forecast

A slow change is coming here over the next few days.  On monday about 5-10cm is expected to fall throughout the day and overnight then starting later in the day on Tuesday we can expected a slightly stronger system to cross the region and give us another 10-15cm.  Long story short, this week we can expect to see 30cm of snow (hopefully) but its gonna still be windy and warm out of the SW. 

Avalanche Summary

No new Natural avalanches were observed.

Snowpack Summary

Very little change out there these days.  The strong chinook flow has continued to batter the snowpack in all open areas.  I believe in some areas even dirt and rock are being moved around...  Sun crusts on the solar aspects and facets and surface hoar on the more northern aspects where it hasnt been beaten down by the winds...  When we do get some new now (expected later in the week) we are likely to have a few layer in the snowpack that will be an issue.

Avalanche Problems

Wind Slabs

Dense wind slabs are common in Alpine terrain and open areas at Treeline, especially in lee and cross-loaded features.
Be careful with wind loaded pockets while approaching and climbing ice routes.>Avoid shallow snowpack areas where triggering is more likely.>

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
