Snowy skies are in the forecast for today and tonight. Although Turnagain Pass is not favored for this storm, up to 3″ could fall by this evening and an additional 3 to 6″ tonight. The Portage zone and areas on the southern Kenai should see rain at sea level but up to a foot of snow by tomorrow morning at the mid elevations. The rain line should hover near 1,000′ and possibly lower. Will this system start building back the mid elevation snowpack? It could be a start, but another warm system looks to move in Monday night.
At the higher elevations, even small amounts of new snow will add weight to our existing snowpack. Sitting anywhere from 1 to 3′ below the snow surface is a thin layer of weak snow (buried surface hoar) . Friday’s earthquake gave this layer a good shake and triggering a large slide may becoming less and less likely, however it is still a concern. We can’t forget this layer is there in terrain above 2,500′, which can be easy as any obvious signs of instability are not likely to be seen. What we can do is listen for whumpfing, use safe travel protocol and choose lower angle slopes if we wish to avoid any uncertainty.
