Although unlikely, it's not impossible to find isolated pockets of stiffer slabs that rests on top of weak faceted snow. Moderate to strong winds have occurred over the past 48 hours, drifting and pressing the snow into stiffer slabs at the surface on leeward aspects and cross-loaded terrain features. Pay close attention to stiffening snow underfoot or any obvious signs of recent wind-loading, as these are signs that you've hit a pocket with this strong-over-weak setup. Any avalanche triggered would be small but could have serious consequences in steep exposed terrain as it may break close to the ground in our shallow snowpack and knock you into rocks or other obstacles.
