Since we have already seen plenty of small loose wet releases this week & a wet slab is potentially more destructive, lets worry first about the wet slab problem. As old wind & storm slabs soak in rain today they will be vulnerable to shearing at thin locations & abrupt changes in slope. Any additional weight added to already soft & melting slopes should have you concerned about the failures above you or triggering these from below. Rain is forecasted today below 8500' & will change to snow as this storm develops later today.
We are back into winter again with up to 2' of new possible. Heavy mountain snow will collect on slopes that may be weakened by rain or that could have perfect crusty bed surfaces for sliding. Strong winds will aid in the transport of storm snow.
As winds shift from South to Southwest today expect loading to occur on North through Northeast aspects. Gusts are likely to reach 75 mph in the alpine creating touchy winds slabs tomorrow. Blowing snow will effect your ability to see & therefore our decision making skills will be altered.
After a warm week the new snow from last weekend has lingered in the trees & on North aspects but has significantly melted everywhere else. Loose wet indicators have been seen lately with one wet slab avalanching in good ski terrain. Wind drifts near & above treeline are measuring 100" while overall coverage is around 45". The top 4" of the pack has undergone several diurnal melt & refreeze cycles & rain will effect slopes below 8500' today. The storm we are anticipating will increase avalanche danger beyond the weekend & into next week.
Since we reopened the BWRA over a week ago there has been a lot of activity. We have seen good numbers of snowmobilers & undergone a diverse avalanche cycle. The avalanche hazard has involved a variety of avalanche problems including: storm slab, wind slab, loose dry, loose wet, wet slab & cornice fall. Although benign, there is still a small chance we could see a deep slab instability as the storm intensifies. Please send us any snow observations that you encounter, we need your input! There are only two of us Rangers out there keeping you informed & open to snowmobiling. Be nice, abide the rules, & stay safe; we're here to help you!

We are on the threshold of another large winter storm entering our area today. Starting off as rain below 8500' this afternoon we will see a wind shift to the SW & cooling temps into the evening. A possible storm slab accumulation of 2' new snow by the end of tomorrow, with another storm at its back through Sunday. Winds will be howling from the S & SW creating large wind slabs on N through NE aspects.
