If you want an image in your head that will help you turn back at the top of a line when you think that there is the potential for avalanche danger - then watch this video...

She got slammed by an avalanche set off above her by an anonymous skier (who skied away...) It was two weeks ago on the first powder day (80cm & high winds) after a month and a half of sunshine - so everyone was pretty excited, to put it mildly.
Thankfully She is safe (as is her friend), thanks to the rescuers (gopro footage) who were able to get to her so quickly and knew exactly what to do.
A good lesson to all of us, me included, to take it easy out there, have the right gear, know how to use it and always continue to learn so that we can stay safe and come home with big powder grins after another great day in the mountains.
