New and wind drifted snow has begun to pile up on the old, tired and worn, and in many cases, faceted snow surface. With so many varying surfaces out there it's difficult to know where all the problems lie but it's safe to say we are going to see an increasing avalanche danger over the next 24 hours. We should initially see some loose, dry avalanches and shallow, sensitive soft slabs within the new as it slides off of either slick and hard, or weak and faceted surfaces in the high country. In sheltered areas, human triggered new snow sluffs are likely to step down into the weak, faceted snow that exists near and below the old snow surface. In exposed terrain, blowing and drifting snow is forming unstable wind slabs on the leeward sides of ridge crests and terrain features. Expect drifts to become deeper and more widespread over the next 24 hours. And finally, as new snow piles up and starts to form a slab over the weak, faceted snow, we are going to see a new persistent weak layer problem. Conditions are changing and we are going to have to be on our toes for awhile.
