Avalanche Summary
Loose dry avalanches to size one from steep rocky terrain were observed across Jasper on Thursday.
Snowpack Summary
Cold temperatures continue to weaken the snowpack. There is a possibility of reverse wind loading from previous NE winds in the alpine. Cold temperatures can cause a wind slab problem to persist longer than normal. Old persistent weak layers are present in the snowpack but continue to facet and are unreactive in snow pit tests.
