Avalanche Forecast

Moderate

Recently, several small avalanches (size 1 to 1.5) have been reported throughout the region, natural and human-triggered. A prevailing trend is persistent slab avalanches, primarily on southerly-facing aspects, ranging from 20 to 50 cm in depth, while wind slabs have occurred on northerly-facing terrain, typically 20 to 30 cm deep.

With more snow, wind, and warm temperatures in the forecast, we anticipate natural avalanche activity to increase in the coming days.

New snow continues to accumulate atop layers of surface hoar in sheltered terrain and a thin crust on sun-affected slopes, approximately 30 to 50 cm below the surface.

Below these layers, the upper snowpack is largely faceted and poorly bonded with another layer of surface hoar in sheltered terrain and a thin crust on sun-affected slopes. This layer, buried in late January, varies in depth but generally exists within the upper 100 cm of snow.

The mid and lower snowpack is generally well-settled and strong.

• Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Avalanche danger is expected to increase throughout the day.
• Be aware of the potential for large avalanches due to buried weak layers.
