Spring-time conditions change rapidly, so have a few options planned for the day.
Intense solar radiation will increase avalanche danger on sunny slopes, while convective storms can locally puke 10-20cm in a few hours, making dreamy pow runs on polar aspects.
A cornice failure from above caught a person on Cheops N 1 today, knocking them downslope ~300m.
A field team around Lookout Col/Ravens area was able to ski cut loose surface sluffs to sz 0.5 in steep terrain.
On Monday, several soft slabs to sz 2 were observed running from steep N-facing terrain on Macdonald.
15-20cm of settled snow is covering a solid crust on solar aspects and old powder on polar aspects.
The mid and lower snowpack is generally strong. However, the basal weakness from November can still be found near the ground in many locations. This layer will remain a concern until the end of the season.
A clearing Wed/Thurs will give way to more convective flurries Fri/Sat.
Tonight: Clearing, Alp low -10*C, light W wind, FZL valley bottom
Wed: Sun and cloud, Alp high -6*C, light SW wind, 1500m FZL
Thurs: Sun/cloud/isolated flurries, 5cm, Alp high -2*C, light S wind, 1800m FZL
Fri: Flurries, 10cm, Alp high -1*C, gusty mod S winds, 1900m FZL
Terrain and Travel Advice
- Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- Closely monitor how the new snow is bonding to the crust.
Small, loose avalanches can be harmful if they push you over a cliff or into a terrain trap. Manage your sluff accordingly; don't let it steer you into something you're trying to avoid!
Aspects: All aspects.
