Critical loading happens when new precipitation or windblown snow overloads a slab sitting on a weak layer. A slab that has reached its critical load may avalanche naturally or with a light trigger.
The suggested threshold for identifying critical loading is 30 cm or more of new snow, or significant wind, or rain during the 24-hour period prior to and up to the end of your day.
