Special Avalanche Warning around the region


An unusual special avalanche warning for the weekend.

  The forecasting agency says the trouble is a weak layer of snow at lower elevations, making the snowpack at the treeline more dangerous than in the alpine.

     The agency says many close calls have been reported in the past few days, because trees aren't the safe haven they normally are.

     The warning says people will need to be aware of smaller slopes, cutblocks, gullies and even just openings in the trees that are primed for human-triggered avalanches.

     The warning covers the ranges from the North Rockies to the South Rockies on Canada's border with the U.S., and includes, North and South Columbia, and Purcells.
