Westerly winds have increased ahead of an incoming storm system, and are currently blowing 15-25 mph across the upper elevation terrain. Even though there is very little snow to transport, I would expect the wind has made some new shallow drifts of wind-blown snow. These shallow wind slabs will be most pronounced on steep slopes facing north, northeast, east, southeast, and south as the wind strips snow from one aspect and loads it onto another.
As always, be on the lookout for snow that is being affected by the wind and avoid those areas. Wind effected snow often looks wavy, rounded, pillowy, and can sound hollow when walking or riding on it.
If for some odd chance, it starts to snow earlier than expected, then it's time to shift our focus on the new snow as well. It would only take a few inches of heavy snowfall to start seeing the loose snow move around on steep slopes. Its spring and weather can change rapidly, as well as the avalanche danger. Always be updating your personal forecast and re-evaluate the snow as you travel.
