High water content and low cohesion in the snowpack means loose wet avalanches can be expected in steep terrain.
Natural activity may slow down during the break in rain today, but saturated snow remains primed for human triggering.
A widespread loose wet avalanche cycle is expected to have occurred throughout the monsoon. Observations have been limited aside from small loose wet activity out of steep, rocky treeline terrain near Arrowsmith and Strathcona on Friday and Saturday.
Natural activity may slow down during the break in rain today, but human triggering remains likely.
Rain has saturated the snowpack to mountaintop. Below treeline, the snowpack has melted out almost entirely, leaving it below threshold for avalanches.
