Slabs may build through the day at high elevations. Travel cautiously, as buried obstacles are a real threat.
Storm slabs may develop in the high alpine as the day progresses. Use caution if you find more than 10 cm of new snow anywhere the snow surface is smooth.
We haven't received any field reports yet. We suspect that any recent avalanche activity occurred in high alpine terrain where stormy conditions may have triggered small slabs.
Looking forward, it is possible that riders could trigger storm slabs as they develop at higher elevations on Thursday. Avalanche activity is unlikely at or below treeline where ground roughness is substantial.
Please consider sharing your observations to the MIN.
Snow depth varies rapidly with elevation. No snow exists below 1000 m. Around 10 to 40 cm of snow exists at treeline. Up to 60 or 80 cm may be found in the high alpine.
On Thursday, around 5 to 10 cm of snow may accumulate at treeline elevations over a wet snowpack. For alpine elevations, 10 to 20 cm of snow may accumulate by the end of Thursday. Southeast wind may create deeper deposits in lee terrain features.
Use extreme caution when travelling, as buried obstacles are a real threat.
