In sintesi

Warm spring like daytime conditions and freezing overnight temperatures is strengthening the snowpack.  Mid elevation winds should keep surface temperatures from getting overly warm and keep wet loose instabilities in check.  Be aware of solar aspects in the afternoon, as warming surface snow may become less predictable.

    Weather forecast today shows it is heating up again to mid 40's and low 50's even at higher elevations, with direct solar impacts on south facing slopes.  With that being said, last night was the 3rd night in a row with a solid overnight freeze with inversion (colder temps in the valleys, warmer temps in higher elevations) combined with moderate active winds mid slope.  Look for signs of loose point release instabilities in the late afternoon on solar aspects like roller balls and wet saturated snow underfoot. Caution should be used when traveling in steeper rocky terrain in the afternoon, where smaller wet loose instabilities and sticky-manky snow could pull you into terrain traps.

    Yesterday traveling at all elevations, signs of old warming runnels were spotted on due south aspects but roller ball and signs of new Wet Loose were minimal or non existent.  Early day surface condtions will be firm and icy.  A sharps kit will be useful for folks getting a true alpine start.  Though north aspects are still holding cold-chalky snow, especially at mid and higher elevations.

Avalanche Discussion

  • Warm spring like days mid winter, summon the exploration of further out, deeper zones in the mountains. Continue to make good plans, travel with experienced backcountry partners and keep safety margins on the forefront of decision making while on quest for new turns.
  • This past week, diurnal melt/freeze temperatures have had a direct effect on the old Deep Persistent week layer we had as a problem over the past several weeks.  We haven't seen or heard of any human triggered instabilities pertaining to that layer in over 10 days. For now we have pulled that problem from our forecast.
