Regions: Kananaskis.

Not a lot of good news over the next couple of days.  Only a few cm's of new snow forecast and a cold front will cause temps to drop into the -20 range so we can look forward to continued weakening of the midpack.  Watch for soft slabs.

Confidence

Good

Weather Forecast

Increasing cloud cover later Monday into Tuesday with some very light flurries in the forecast that will likely only total a few cm's.  An arctic cold front will slip into the area on Tuesday dropping temps into the -20 range .  Some gusty NE winds Monday night swapping to more W / NW  on Tuesday.

Avalanche Summary

No new observed or reported on Monday.

Snowpack Summary

Little change again over past 24 hours with only trace amounts of new snow falling in valley bottoms and 1-2 cm at treeline. Light to moderate westerly winds continuing to stiffen windslabs on immediate lees slopes and in gully features.   

Avalanche Problems

Wind Slabs

30-40cm thick hard windslabs are being encountered on north to southeast aspects at treeline and above. Expect wide propagations due to the hard nature of these slabs.
Be aware of the potential for wide propagations due to the presence of hard windslabs.>Be aware of thin areas that may propagate to deeper instabilites.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4

Storm Slabs
