  You could still trigger an aging wind slab at mid and upper elevations. As time goes on, wind drifts are likely to become stiffer, harder to trigger, and also hard to test for. Fortunately, wind speeds are expected to be light through Sunday, minimizing any new growth.

  Look for visual clues to identify wind loaded terrain, such as lens-shaped surfaces, sharp wind lips, or dense, wind compacted surface snow. If these things are present, slopes down wind may be wind loaded. If triggered, these slabs could break larger than expected. The safest move is to stick to simpler, wind sheltered terrain for another day.

  As temperatures rise and the sun shines, wet avalanches will become increasingly possible on southerly aspects at low, mid, and upper elevations. As the snow trends warmer, there will be signs such as snow turning sticky and heavy, trees and rocks shedding built-up snow, and roller balls forming on steep slopes. This problem should be pretty straightforward to navigate: as temperatures climb, move to shaded slopes or stick to lower-angle, sunny terrain.
