Saturday will bring our first bout of real cold weather. Pack extra warm clothes and plan to finish your run with plenty of daylight remaining, in case anything goes wrong.
Snowfall and wind refreshed the storm slab problem on Friday. This will be most reactive in wind affected terrain in the alpine and open areas of tree line.
If Northerly winds accompany the incoming cold air, watch for reverse loading of typically windward slopes .
There was a cycle of natural avalanche activity in steep open terrain Thursday night into Friday. These were mostly size 1.5-2.5, with a few size 3s from Mt. Tupper and Mt. MacDonald.
Another 15-20cms of low density snow fell Friday building fresh soft slabs, especially in the alpine and open tree line areas where new snow has been redistributed by SW winds.
The mid and lower snowpack are generally strong. There are a couple of buried crusts at Treeline and and below, but these have not shown signs of reactivity in our area recently.
Arctic air briefly infiltrates our area, bringing cold temps, and possibly some N winds.
Tonight Scattered flurries (up to 5cm). Alpine Low -21°C. Ridge wind gusty moderate, West switching to NW.
