Avalanche Forecast......
ALPINE .....Considerable
TREELINE....Considerable
Below TREELINE....MODERATE
TRAVEL Advisory....
Riders and Skiers can expect to be dealing with the aftermath of Mondays Storm for another day or so, in combination with New Snow fall and continuing Strong Winds.
Wind loading and Slab formation has occured at all Elevations, and will continue to present route finding and Risk Assessment Challenges to Back-Country Users. Although Natural Avalanche Activity have tapered off, with Strong Winds expected to continue through the week , We can predict the upper Snowpack where wind loaded , will persist in a state of instablity and Easily Triggered by Skiers and Sledders. The North Columbia received Larger Snowfall this week and consequently has Deeper Slabs, which when riggered, will produce more Destructive Avalanche and have a Greater potential for stepping down into deeper layers. Results on Deeper Layers such as the Dec. 5 Rain Crust, continue to be only occasional, but produce Avalanches Large enough to Destroy a Pick-up Truck, and to Threaten Travel Routes which cross Avalanche run-outs.
AVALANCHE ACTIVITY.....
The first half of this week saw a widespread natural Avalanche Cycle resulting from Mondays Storm. Many locations in the North Columbia reported Observations of Natural Avalanches across a variety of aspects and over a Wide Range of Elevations.
These events involved primarily the upper 20-60-cms.of Storm Snow, and were triggered by strong winds and the resulting Snow re-distributions and slope loading.Many of these slides were large enough to Bury a Skier.One further additional notable event was a slide initiating in wind slab and then stepping down to a weak layer dating back to Nov. 24 , and becoming Powerful enough to Destroy Trees along the Edge of the Avalanche Path .
SNOWPACK.....
New Snow and Strong winds over the last couple of days have resulted in wind slab formation up to 60 cms. deep in ALL Open Areas, from Valley bottom to Ridge Tops ( Hard Slabs ), Other notable Features of the Upper Snow pack include isolated formationof Feathery Surface Hoar Crystals , and a Thin Crust created by Mondays Freezing Rain, Now Buried up to 40 cms. Deep, An otherwise stable mid-pack harbours the Dec .5 crust/facet interface down 80-160 cms.
Blue River was Cloudy with the Sun popping out now and again.
Temp. -10
Friday....Chance of Snow
Saturday & Sunday look for Sunny Skies and a Temp. of -7 or -8
Looking Perfect for those Mountain Pictures and Videos !!
Blue River Welcomes You !!
