If you're getting out in the extreme cold, remember that freezing temperatures make for higher consequences.
Reverse loading will likely create small pockets of wind slabs in places you might not expect them.
Strong outflow winds will have the potential to generate reverse loading and build pockets of wind slabs at alpine and upper treeline elevations. In frigid temperatures, slabs may take longer than usual to heal and bond to the snow below them. Avoid wind-loaded features during this time of continuous strong north winds.
No avalanches have been reported in these areas. This is likely due to the shallow snowpack limiting riding opportunities for the time being. If you venture into the backcountry, please consider submitting a MIN report, as it helps to strengthen our data gathering.
Winds have shifted north Friday and Saturday, moving available snow back to south aspects and potentially creating fresh slabs. The snowpack is generally highly wind-affected, resulting in a wide variation in snowpack depths. Ridges and high points at upper elevations have been scoured, while deep loaded pockets on northerly slopes are up to 150 cm. Treeline snow depth range from 60 to 90 cm.
An arctic front is sliding throughout the region. Gusty northerly outflow winds and cold temperatures will persist into next week. Dangerous wind chill values are expected.
Saturday night
