Lo esencial

Generally safe avalanche conditions will be found across the Selkirk and Cabinet mountains today. Wind-drifted snow from a storm over the last 36 hours is sitting on a firm, frozen snowpack. You may find shallow wind-drifted snow in isolated terrain capable of producing an avalanche. Use caution on steep wind-loaded slopes.

     A few inches of low density is snow sitting on top of the sun crust from earlier in the week. Light, drifted snow can be expected near treeline and above, across the Selkirk and Cabinet mountains.  A moderate southwest wind  primarily load northerly slopes, which may make for deeper drifts on those aspects. Triggering an avalanche in wind-loaded areas is possible today. Feel for heavier, denser snow and keep an eye out for wind effected surfaces. Drifts can be expected in isolated areas such as  gullies, rollovers and around terrain features such as rock bands or road cuts. Pay attention for shooting cracks or recent avalanche activity.

    Hand pits will be an effective tool for determining how well the new snow slides on the old snow surface. Above treeline areas are the most likely place to find wind-affected snow. Managing the slope angle will manage the problem!

Avalanche Discussion

Below freezing temperatures today will make for little change in the snowpack. Cloudy conditions and light snow are forecasted, so don’t expect big changes as the day goes on. Mostly you can expect a firm snowpack with light snow on top. The snow depth will vary depending on the aspect and elevation. You’ll find more snow as you travel up elevations. Primary winds have been out of the southwest, deeper wind-drifts live on northerly aspects.

I can’t believe the snowpack is hanging in there as well as it is, especially at lower elevations. Access to lower trailheads is still pretty good. Current SNOWTEL totals put the Snow Water Equivalent in North Idaho at 92%. We’ve had the “in like a lion” part of March, maybe the “out like a lamb” is on it’s way! Have a great day! Enjoy the snow, while we still have it!

IPAC Avalanche forecasts will continue until Saturday, April 1st. After April 1st we will still issue spring riding tips, Watch’s and Warnings in necessary.
