It is a good time to be traveling in the mountains, but remember that low danger does not mean no danger. Loose wet avalanche activity should be limited Wednesday, but stubborn old wind slabs and large cornices demand our respect.

Weather Forecast
Wednesday looks to be the last day of rather vanilla weather before a significant change Thursday. The pattern is incredibly dynamic as we move towards the weekend, this is a great time to check out our Mountain Weather Forecast (link below) if you are curious.

THURSDAY: Overcast, freezing level starting at 1600 m, lowering to 700 m by sundown, strong southerly wind, 20 to 30 mm of precipitation.

Avalanche Summary
No recent notable avalanches have been reported.
Snowpack Summary
Last week's storm brought up to 15 cm of new snow to the alpine while rain saturated the upper snowpack at treeline and below. Surface conditions on solar aspects and below about 1500 m have been affected by daily melt-freeze cycles. In the limited alpine terrain where the recent precipitation fell as snow, stubborn old wind slabs may remain sensitive to human triggering.Below any recent snow accumulations, the overall snowpack is well settled and strong. Cornices loom over many ridge lines. Cornices become more unstable during the day as the temperature rises, especially when they are receiving direct sun.
