Problem #1 Comments
The winds from this storm were very strong as seen by the widespread windslab and the lack of new snow in any areas effected by the wind. The winds had sustained speed of ~30mph above 8000' with gusts up to 60mph. New windslab seemed to generally be unreactive but we stayed away from steeper and more exposed areas. From Little Water we could see the wind loading on Sheep Shit Ridge and Reynolds.
Comments
Tour started around 0845 from Spruces up to Dog Lake and across to Little Water Peak. No precip from the beginning to end of our tour; precip from overnight consisted of dendrites with some graupel. As we approached the summit, the winds began to ramp up with sustained wind at ~30mph and gusts up to 60mph from the WNW. While the wind direction was generally from WNW, the wind blew from about every direction at one point or another. New snow was deposited in low elevation valleys from the scoured ridges. Toms Hill, Pow Park 3, and Reynolds had good coverage with Reynolds being heavily wind loaded. Deso, PC Ridgeline, and Pow Park 1 areas had a lot of exposed ground from the winds.
The snowpack structure, while unreactive during our tour, was concerning. This last storm deposited higher-density snow (either as new snow or wind slab) over low-density base. It appears that there are all the ingredients for widespread avalanches but we haven't reached the tipping point. With winds continuing into tomorrow with little precip, it is likely that wind slab formation will continue.
