Good morning, this is Evelyn Lees with the
Under clear skies, temperatures at most elevations are well below freezing for the third morning in a row – in the mid to upper 20’s. The northeasterly winds are in the 5 to 15 mph range, with a few of the most exposed stations having gusts to near 30 mph. The typical spring turning, riding and snowshoeing conditions are very good, with isolated powder on steep, northerly facing slopes above about 9,000’ and supportable crusts on the other aspects. As the crusts soften, it may just be some of the best corn of the year, and with precise, Swiss-like timing, it’s possible to make a full day of it in the backcountry by working aspect and slope angle.
Snow and Avalanche Discussion:
No new slab avalanches were reported from the backcountry yesterday, though a few crusted slopes did soften enough to get a collapse on the damp snow below. Push-a-lanches were possible on steep, sunny slopes as the surface snow heated up and shallow, loose sluffs were easy to trigger on the steep, shady slopes.
As you head into the backcountry today, you’ll have to deal with the typical heat related wet snow problems, just a bit trickier due to the some faceted layers. As usual, you want to be off the sunny slopes before the snow heats up. If the snow is becoming punchy, sloppy or the crusts “bendy”, it’s definitely too warm and you need to immediately switch to a cooler aspect. Corn slabs are possible today, when what appears to be a solid, frozen crust fails on a wet layer beneath. So as you travel, monitor the depth of the refreeze often by digging down or jabbing your pole handle into the snow.
On the steep, northerly facing slopes there remains an isolated chance that a person could trigger a slab avalanche, in thinner snowpack area or shallow rocky area. So no matter where you travel today, continue to use good, safe travel techniques of one at a time on any steep slope and observe your partner from a safe place.
Bottom Line for the
The avalanche danger is generally LOW this morning, and will rise to MODERATE on slopes steeper than about 35 degrees with daytime heating. The rising danger will follow the sun – first on easterly facing slopes, then south and then west. Carefully monitor snow conditions, and get off of and out from under steep sunny slopes as they heat up.
A warm and mild
weekend is in store for northern
