Avalanche Forecast
Regions: Jasper.
Weather Forecast
Jet stream lies over BC bringing strong NW alpine winds for next couple of days. 2 systems will bring continuous yet light snow with potentially more amounts in the Icefields. A snow warning exists just to the West which may trickle into the Icefields area. Milder temperatures are expected next couple of days and reduced winds by Tuesday.
Snowpack Summary
Moderate gusting strong swirling alpine winds are transporting the available 20cm or more of surface snow. Expect variable loading patterns with local terrain influences. Saturday's snow pit above Parkers Slabs was 190cm thick on a well settled mid pack. Whatever was on the surface is likely getting redeposited. Still overall variable snow depths.Â
Avalanche Summary
Saturday three size 2-2.5 avalanches were noted now 48-72 hours old, 40 degree plus, NW aspect, cross loaded gullies. Thursday' s explosive work on parkers slabs with 22 avalauncher rounds produced one size 2 slab avalanche in a wind loaded location on smooth steep rock slab. Patrol South today had limited visibility but swirling winds encountered.
