Thursday will be the last day of low avalanche danger before a major storm moves in that night.
Watch for small wind slabs developing Thursday afternoon.
Small wind slabs may start to form late in the day as 5 to 10 cm of new snow gets blown by southerly winds onto leeward slopes.
No recent avalanches have been reported.
With the cooling trend and limited new snow in the forecast, we expect avalanche activity will remain unlikely on Thursday. However, as storm snow accumulates Thursday night and Friday, avalanche danger will rise rapidly.
If you are headed into the backcountry please consider submitting a MIN report.
Previous strong sunshine and warm temperatures formed a crust on most surfaces, except on north-facing alpine slopes, where some older soft snow possibly remains. Surface faceting has been reported in shady, sheltered areas. 5 to 10 cm of new snow is expected to fall Thursday, with significantly more arriving Thursday night and Friday. The mid and lower snowpack is dense, well-settled, and currently free of concerning layers.
For more details check out this MIN from our field team at the Victoria Peak area last Tuesday.
