Avalanche Forecast
Regions: Waterton Lakes.
Weather Forecast
Weekend temperatures will rise to just above freezing at mid elevation during mid day. Combined with solar influences watch for weakening of near surface layers and ridge line cornices. No new snow is forecast. Expect moderate westerly winds.
Snowpack Summary
Hard slabs are now found in all open areas at treeline and above. They overlie a layer of low density snow on top of strong temperature or sun crusts or old wind slabs. Deeper persistent instabilities are presently bridged by a strong mid-pack in most locations. Watch for shallow higher elevation areas where triggering is still a possibility.
Avalanche Summary
March 4 saw a small cycle of natural avalanches failing on the previous crusts down 20 to 40cm as the snow from earlier in the week was redistributed on to northerly lee areas. No avalanches were observed on Thursday, March 5th
