[MCR] Mistaya Lodge, Rockies - storm update January 14

Subject: [MCR] Mistaya Lodge, Rockies - storm update January 14
Date: Fri, 14 Jan 2011 08:51:00 -0700
In the past 48 hours we have recorded 60 cm of low density storm snow at 2000m 
at Mistaya Lodge near the Wapta Icefield.  The snowpack is now 165 cm deep, 
with a 63% increase in snowpack depth as a result of this two day storm.  And 
it is still snowing this morning, with calm wind at the lodge.
Temperatures have moderated to a daytime high of -6 and overnight low of  -13.
Limited observations yesterday (Jan 13) due to poor visibility.  Good ski 
quality with no signs of slab development at our 2300 m treeline high point. 
In sheltered areas below treeline the January 12 surface hoar is 3 mm and was 
producing sudden planar shears but was not reactive to skiers.  
The deeper persistent weak layers may start to wake up with this rapid loading.
With 39cm of the storm snow falling in the past 12 hours since we were last out 
skiing, rising temperatures and humidity, and possible wind at treeline and 
above, we are calling avalanche danger HIGH at all elevations today (January 
14).
