Heavy precipitation with a shifting snowline make it tough to pin down the scale and extent of Wednesday's problems. Raise your guard where you find dry snow in above-threshold terrain.
Wind slabs may exist in alpine areas that managed to dodge rainfall Tuesday night. Raise your guard where new snow is dry. Observations are limited, so assess any suspect features carefully.
No recent avalanches have been reported. Observations are limited in this area, but so is the snowpack.
If you head out into the backcountry, please consider sharing your observations on the MIN.
A mix of snow and rain did little to improve snowpack coverage on Tuesday. Higher alpine locations might have seen 5 - 10 cm accumulate before it was again affected by rain.
Cooling temperatures on Wednesday should freeze the wet snowpack in place. Limited wind slab problems may form in alpine areas high up enough to have dodged rainfall.
Before the storm, higher treeline areas held an estimated 20 to 50 cm of snow. This diminishes rapidly below 1500 m.
