In sintesi

A MODERATE danger still exists for deep and dangerous, human triggered avalanches failing on a buried persistent weak layer of loose, sugary, faceted snow primarily on slopes facing NW-N-E. Avoid steep, wind drifted slopes and likely trigger points such as steep convexities or shallow snowpack areas near rock outcroppings or sub ridges. With a strong sun this time of year, always be on the lookout for an increased danger for loose, wet avalanches on sun-exposed slopes. Signs of instability include pinwheels, rollerballs, and point release sluffs. Get off of and out from under steep slopes that become wet and sloppy.

    Though the odds are decreasing, it is still possible to trigger a deep and dangerous avalanche failing on a persistent weak layer of loose, sugary facets that formed in February. Significant snowfall and strong winds have built slabs 2'-4' deep over top of this weak snow. You are most likely to trigger an avalanche involving this persistent weak layer on steep, wind loaded, north through easterly facing slopes right around treeline, or in shallower, rocky areas in the alpine. Avoid likely trigger points such as steep convexities or thinner snowpack areas around rock outcroppings.

    Isolated, unstable wind slabs may still exist in the high country primarily on slopes facing NW-N-E. Most of these wind slabs have stabilized over the past couple of days, but their weight has put additional stress on buried, persistent weak layers. For this reason, it is still a good idea to avoid steep slopes that look fat or wind loaded.

NWS weather forecast

Weather: Skies are clear, NW winds are mostly light and it's cold up there! Continued light winds will shift to the SW, and high temps will climb to just above freezing. We should see some clouds developing later today ahead of a weak shortwave that will move through the area tonight. The weekend looks sunny and warm with high temps in the mid 40's. Overnight lows will drop into the mid 20's setting the stage for a good melt-freeze cycle and possibly some good corn skiing on S-W aspects. The long term forecast shows a Pacific low taking its time moving down the coast and eventually onshore by mid next week. things look to remain pretty quiet through Wednesday.

Snowpack: Reed Kennard was up yesterday and he reported winter weather with cold temps, steady SW winds, and consistent light snowfall though with little to no accumulation. He reported a mixed bag of spring-like transitional snow conditions. Read his observation here.

After a long dry spell in February, March saw significant snowfall, generally accompanied by strong southerly winds. Accumulating and wind drifted snow piled up on top of loose, sugary, facets that developed in February. This combination produced both natural and human triggered avalanches from 1'-4' deep. This problem still exists on northerly aspects, especially in areas with a thinner, underlying snowpack.

We're approaching traditional peak snowpack depth and we've managed to creep back up to just above average. The highest depth in Gold Basin this year was over the weekend with 74" on the stake.
