What time of day or year are avalanches most likely to happen?

ANSWER!
my answer to this question it would have to be when it is really cold and snowy and the snow rumbles it crashes down
My understanding was right before or right after winter. I can't tell you for sure, though.
This is an educated guess only: The most likely time of day for an avalanche would be in the afternoon and the most likely time of year would be in the spring. The logic behind this "guess" is that as the temperature begins to rise (i.e., in the afternoons and in the spring), the snow begins to melt resulting in the weight of the snowpack becoming heavier until reaching the point where the underlying snow is no longer able to support it and lets loose. This is assuming there is no external triggering event such as an earthquake.
