If we sound a bit like a broken record, it’s because conditions are not changing much day to day. Stability remains very good. Snow quality is variable with some good skiing and riding still to be found.
The most likely mountain hazard right now seems to be unrelated to avalanches or snow stability. 2 helicopter rescues in the last week underscore the hostility of steep terrain even in perfect March weather. This is a good reminder to be prepared and don’t let your guard down, especially when stepping it up to the big mountain steeps. Sometimes crampons, ice axe, a rope and the mountaineering training to use them are warranted in our bigger mountain terrain.
Stability problems to look out for today:
Overhanging cornice features are unlikely to fall spontaneously, unless the temperatures really ramp up today. They may fail if you add some weight and stress by walking/skiing/riding over them. The first rule of cornices is to give them space.
Wet Loose avalanches:
We have yet to see much of this type of activity, but it is coming with longer and warmer days. Keep it in mind on south facing aspects late in the day.
Old Wind Slabs:
Stiff snow is likely to be bonded well to the layers underneath. However, be prepared for small plates to break off in steep terrain. This isn’t really a burial hazard, but rather a “knock you off your feet” kind of hazard, which could be dangerous in high consequence terrain.
The last storm ended on Friday 2 weeks ago.
Skies look clear again today. Wind will continue to be light. Temperatures are freezing hard at night with lows into the teens or lower in some areas. Daytime temperatures are reaching into the high 30s or more by afternoon. The graph is the diurnal temperature fluctuation at Summit Lake from the last several days.
Weather through the weekend looks like a continuation of our current pattern. There is a hinting of a pattern change in the longterm forecast, which may mean more clouds and possible precipitation next week.
