As time goes on, the snowpack adjusts to all the snow from mid January and the chances for triggering an avalanche become less. However, the snow at the base of the snowpack remains very weak. In areas where the snowpack is shallower, the whole structure is weaker and these are the places you're likely to trigger an avalanche. If you find that you are sinking deep into the snowpack while traveling (skis diving deep or track dropping through), this is a clue that you are probably in a shallow, weak area.
I have zero tolerance for faceted snow at the base of the snowpack. It is way too unpredictable. My personal strategy is to simply avoid steep terrain until the snow at the base gains strength.
