Small wind slabs may be forming at upper elevations
Verify that conditions are safe before committing to steep slopes
Fresh wind slabs may form on lee slopes during periods of snowfall on Sunday. Check how well the new snow is bonding to the underlying crust before entering comitting terrain.
No new avalanches have been reported.
Observations have been extremely limited in this region. It's a good idea to frequently verify if conditions match the bulletin and adjust your terrain choice accordingly.
Please share to the Mountain Information Network if you head into the backcountry.
Snowfall of 5 to 15 cm is expected to fall at upper elevations overnight and through Sunday. This new snow may build small wind slabs on lee north through easterly slopes. Otherwise, a typical spring diurnal cycle is underway. Warm temperatures during the daytime melt the upper snowpack, making it moist or wet. Cooling at night then usually forms a hard crust at upper elevations. Lower elevations may not refreeze overnight and are melting out rapidly.
The snowpack is generally well-settled and strong, although dormant weak layers may still exist in some areas.
