    For some reason this doesn't surprise me, seeing as though Kirkwood is reporting up to 8 feet at the higher elevations over the last 4 days. There's plenty inbounds going off right now. No reason to be heading into the backcountry just yet.

    Hopefully the new snow is bonding, but I bet we see some big naturals before that happens. Is it going to stay cold between now and Saturday?

    Decreasing winds and minimal overnight precipitation are giving the snowpack a chance to bond and stabilize. Formal tests continue to produce shears 4 to 5 feet deep in the storm snow layer and at the buried melt freeze crust found at the old/storm snow interface. Easy human triggering of avalanches is still occurring on test slopes. Significant avalanche danger continues to exist in the backcountry. Avalanche danger is CONSIDERABLE near and above treeline on NW through SE aspects steeper than 32 degrees. Below treeline, avalanche danger is MODERATE with pockets of CONSIDERABLE on terrain steeper than 35 degrees. Despite a decrease in natural avalanche activity, human triggered avalanches should be expected by backcountry travelers. Some avalanche activity may be surprisingly large.

    Mountain Weather 2 Day Forecast
    Mostly cloudy skies today with scattered snow showers. Mountain valley highs 32 to 42 degrees. Overnight lows 18 to 28 degrees. Friday will be partly cloudy with mountain valley highs 37 to 47 degrees. Moderate southwest winds will continue to decrease Thursday before an increase in speed and easterly shift overnight into Friday. Moderate southwest winds are forecast to return Friday afternoon.

    Today's Safety Tip
    Do not let your guard down as this storm subsides. Significant instability remains in the snowpack and is waiting patiently for you to apply to needed trigger. Human triggered avalanches will occur today if you apply the trigger on steep terrain. Utilize safe, protected routes in all aspects of travel for ascending, descending, and traversing. Strive to pick the best areas and do not let convenience lead you into questionable terrain.
