A wintery storm will bring a change in avalanche conditions in high terrain on Sunday.
This will be our last forecast for the season. Check out some alternative resources for spring here.
On Sunday, new snow and wind will form fresh slabs at upper elevations. Slabs are likely to be most reactive in wind-loaded lees and where they sit over a crust.
Small (size 1) natural and skier-triggered wind slabs were reported earlier in the week. Otherwise, no new avalanches have been observed.
Last week, large cornice failures in high north-facing alpine terrain notably did not propagate any weak layers on the slopes below. This is a good indicator of snowpack stability under current conditions.
New snow is forecast to fall on Sunday, over widespread crusty surfaces on all but high north-facing alpine terrain, where snow is dry and likely wind affected.
There are no deeper concerns at this time.
