Avalanche Advisory published on January 14, 2021 @ 6:19 am
Issued by Steve Mace - ESAC

LOW avalanche danger exists at all elevations today. Be on the lookout for isolated areas of unstable snow today, particularly on unsupported slopes or in extreme terrain. Shallow coverage, variable surface conditions, and a plethora of obstacles remain the biggest hazards to backcountry travel.

advisory discussion

While it is important to remember that unstable snow may be possible to find on isolated terrain features today, the challenging and variable surface conditions should be top of mind for anyone heading into the backcountry. Sticky wet snow was observed on all aspects yesterday at mid and lower elevations while a variety of challenging wind affected surfaces remain at higher elevations. Our current spring-like weather pattern is rapidly affecting our snowpack but it will take some time for the transition to occur. Expect the full range of challenging surface conditions today from sticky residual powder snow in sheltered trees, unconsolidated wet snow on shallow solar aspects, firm wind affected surfaces in exposed areas near and above treeline, unsupportable faceted snow in more shaded areas near treeline, and a variety of breakable surface crusts around the compass rose. The obstacle-ridden landscape remains the biggest hazard to backcountry enthusiasts, be aware of your exposure and keep in mind that even an otherwise innocuous fall could have severe consequences with our extremely shallow coverage.
