If you find a shallow spot on a steep slope, you can trigger an avalanche that will break on weak layers in the top meter of the snowpack. Avalanches triggered on steep northerly and easterly slopes will be larger. Recent easterly winds loaded westerly slopes, creating a more continuous snowpack. Assess the slopes you plan to travel and identify and avoid shallow trigger points.
After multiple days of warming, loose wet avalanches are less likely, but not out of the question in the afternoon. Avoid traveling on or under slopes where you observe rollerballs, pinwheels, or fan-like point releases.
