In sintesi

Heads up... a solid shot of snow and wind leads to rising avalanche danger by Saturday morning, especially for the east side of the range where the snowpack is unusually weak and fragile.

For today-

While not widespread, you'll find pockets of MODERATE avalanche danger in upper elevation alpine terrain, especially on steep leeward slopes facing the north half of the compass. Fresh snow, coupled with older wind drifts will react to our additional weight and human triggered avalanches are POSSIBLE. While more the exception than the rule, any avalanche that breaks to weak layers of snow near the ground will result in a deep, dangerous avalanche that'll instantly ruin your day.

Mid and low elevation terrain offers generally LOW avalanche danger. Remember- low avalanche danger doesn't mean no avalanche danger, so please continue practicing your safe travel rituals and make sure you carry and know how to use your avalanche rescue gear.... transceiver, shovel, and probe.

    Avalanches can still break deep and wide. This hard slab triggered Sunday on the Hoyt Peak shoulder is a sizable chunk of snow that broke 4'-6' deep x 400' wide, but due to the terrain characteristics, only ran about 100' vertical.

    The good news is... where the snowpack is deep, it's happy in its own skin. However, snow is a curious medium and all we need to do is find one inconsistency or a shallow zone, maybe around a rock or bush, collapse the pack, and now we've got a bigger slide than we might've bargained for. So my safe travel strategy is to think about suspect terrain I want to continue avoiding and that includes steep, rocky terrain and slopes that avalanched near the ground earlier in the season. And here's something to consider... we've got a "go anywhere" base, so if you're getting into steep, technical terrain, remember that even a small slide can knock you off your ride, slam you into a tree, and throw a curve ball at your day.

    Shaun and Weston D traveled into the big, alpine terrain near Bald Mountain and found a snowpack making its best attempt to get stronger. And while we appreciate the sincere efforts the snowpack is making, gains don't come easy and it may be a little too late in the season for the pack to build up the strength it needs to totally turn the corner. More on Shaun and Weston's travels found HERE.

    Any bump in wind speed will instantly whip up shallow drifts reactive to our additional weight. Found mostly along the leeward side of upper elevation ridges, I bet a few fresh form around terrain features like chutes and gullies. Easily managed with terrain choices, simply lose some elevation and you lose the problem.

Recent Activity

Common theme... fresh wind drifts in the wind zone crack with the additional weight of a rider, but are easily managed and avoided by losing a little elevation. Meanwhile, Michael J found fast running sluffs on steep, sustained slopes and has a great ob HERE.

Snow and Weather

Nowcast-

Yesterdays' storm over-delivered, particularly for the North Slope, where most upper elevation terrain stacked up 10" of cold, white smoke. The south half the range faired well too, clocking in with 6" of low density snow. With clearing skies overnight, temperatures crashed into single digit territory. Along the high peaks southeast winds blow 15-20 mph. Recent storm snow worked its magic to improve riding and turning conditions, but there's still some firm crusts out there, so to avoid bottom-feeding, low angle slopes are gonna be the ticket.

Forecast-

A short-lived break in-between storm systems provides clear skies with temperatures climbing into the teens. Winds remain light and southeasterly, blowing in the teens and 20's along the high ridges. Snow develops overnight, increasing in intensity by the morning.

Futurecast-

A cold winter storm delivers a good shot of snow for the region. Expect snow to begin stacking up in earnest during the day Saturday with storm totals in the 4"-8" range for the North Slope and 10"-14" for the east side of the range.
