Steer clear of steep, open slopes and consequential terrain features. Storm snow needs time to bond with the crust below, and is likely more reactive at higher elevations.

Avalanche Summary
No new avalanches have been reported in the region. We expect natural and rider triggered avalanches to occur overnight Thursday and throughout Friday.
If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.
Snowpack Summary
Overnight snowfall may reach up to 30 cm in some areas, redistributed by southwest winds into deeper deposits on north and east facing slopes. Storm snow buries a melt-freeze crust, existing on all aspects at treeline and below. The crust extends into the alpine on solar aspects. In north-facing high alpine terrain the surface snow may have remained cold and dry.
The mid and lower snowpack is generally well-settled and bonded.

Terrain and Travel Advice
- Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
- Be careful to keep storm day fever from luring you out into bigger terrain features.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Problems
Storm Slabs
Overnight snowfall will create reactive storm slabs sitting a melt freeze crust and surface hoar. Avoid terrain capable of producing large avalanches, storm snow will take time to bond and settle. Low elevations may receive a mix of rain and wet snow.
Watch for deeper and more reactive deposits in wind loaded terrain features on north and east facing slopes.
Aspects: All aspects.
