Gale force winds aloft are responsible for recent wind loading. All aspects at mid and upper elevations have been kissed by the wind the past couple of days. Be aware of catchment zones on leeward slopes and just below ridges as triggering an avalanche in these areas is possible.
Sustained NE winds over the past couple days have reached speeds of over 100 mph. Horsetail wind vanes were visible on most Sierra peaks and ridges yesterday, from the strong-sustained NE wind. Wind loading and cornice's formed throughout the day on alpine, leeward and crossloaded SE/S/SW/W/NW. Be cautious and aware if traveling in this terrain.
Clear-cold, high pressure days this week are producing solar influenced loose wet avalanches in mid and lower elevations. Mid february sun angles are heating up solar aspects with poor snow coverage. Specifically in darker rocky outcroppings from radiant heat. These loose snow avalanches are being triggered late morning to mid afternoon and may be large enough to sweep you off your feet. Be cautious if on southern aspects during these times, especially in consequential terrain.
