Avalanche risk The Bottom Line

Avalanche danger continues to be LOW across our forecast zone.  The shot of snow that impacted Anchorage yesterday had very little effect to the south of Anchorage.  Mountains around Girdwood got up to 3 inches of light snow, Turnagain Pass got about an inch.  This minimal snowfall did not change the avalanche danger in our area.  

Surface conditions are still supportable crust interspersed with old raised tracks.  Skiing and riding quality is poor.  This crust could allow for easy travel into the far reaches of the Chugach on skinny skis or a fat tire bike.

Normal Caution means triggering an avalanche is unlikely but not impossible.

A complete lack of soft snow below 4000 feet makes avalanches an unlikely possibility.  

We’ve had a recent pattern of melt/freeze: temperatures alternating into the 40s F during day and freezing hard at night.  This has consolidated the snowpack and made it strong and firm.  Despite the presence of several crust layers, the snowpack is quite stable.  

Exceptions could exist at very high elevations that were not affected by melting temperatures.  If you look hard enough there are always be outliers to be found.  

Cornices are the other stability exception.  Unstable overhanging curls of snow at ridge crests can be found without much searching.  They can and will break back farther than expected if a person were to step onto one of these features.

 

Weather
Thu, March 6th, 2014

The snowfall yesterday hit Anchorage harder than Girdwood or Turnagain Pass.  There may be a slight benefit to the quality of skiing from this 1-3 inches of snow, but it is minimal.  

Mostly cloudy skies this morning will become partly cloudy by tonight.  Patchy fog in the morning.  A few flurries in the morning are not expected to produce significant snow on the ground.  Temperatures will reach into the lower 30s.  Wind will be 0-10mph.  

A chance of snow is forecasted for the weekend, but it doesn’t look like a major storm that will produce much snow.
