New snow will not bond well to previous surfaces of solar crusts and well settled powder from the recent high pressure. Expect reactivity as you enter your line, ski one at a time in steeper terrain, and be aware of what/who is below you.
Expect loose snow avalanches in steep terrain - these could gain sufficient mass to take you for a ride in confined terrain such as gullies.
New snow and wind will build fresh thin slabs in open terrain.
No new avalanches were observed or reported on Friday.
On Thursday, there were a few loose wet avalanches, up to size 2, from steep terrain in the highway corridor.
There were a few isolated glide slab avalanches this week from steep south facing terrain of Mount Tupper. A size 3 from Tupper Minor on Wednesday, a size 3.5 from Mounds on Tuesday, and a size 2.5 from Lone Pine on Monday.
Incoming new snow is covering a solid crusts on solar aspects, and 5-10cm of settled old powder on polar aspects.
The mid and lower snowpack is generally strong. However, the basal weakness of rounding facets/decomposing crust can be found near the ground in many locations, and will remain worthy of consideration until the end of the season.
A weakening cold front moving inland will bring snow flurries to Rogers Pass overnight, the "storm" will peak early Saturday morning.
