                     Thanks to Gabriel Alary for this photo of avalanche on Fissile April 18, 2014.

    Nice light first thing yesterday morning. Mostly sunny, that changed just after mid day.

    Obscured in the afternoon.

    Not ideal conditions for the slope style competition.

    Sunday was the last day for the GMC Race Centre.

    Some decent conditions yesterday morning.

For the forecast, the stationary front will send clouds into our area today into this evening. South to Southwest flow will bring light precipitation amounts.  The front and an associated upper trough will move through by Tuesday morning. Wednesday is looking like an unsettled day with weak ridging and off shore flow. A weak warm front will move into our area for Thursday. Friday is also looking unsettled at this time with increasing clouds during the day and some light precipitation by the evening. Guesstimates: 3-5 cm by Tuesday morning, 2-4 cm by Wednesday morning, 3-5 cm by Friday morning. Freezing levels will rise to 1900 meters today than fluctuate between 1200-1600 meters into Thursday.




    As of 07:00 hrs we have obscured skies with limited visibility and it is snowing.

Avalanche control in the area yesterday produced mostly size 1 avalanches; Xe, Xc, and Sc.  A few size 1.5,  4f windslabs running on most recent melt freeze crust.



    Unsettled yesterday morning with some nice sunny periods. Clouded over later in the day.

    Looking like some moisture coming our way for Thursday.
