Evans - goodbye stability

<p>Conditions fully changed on Saturday afternoon. Intense solar radiation and what appeared to be higher than forecasted freezing levels saturated the snowpack. We called it a day on the ridge of mt evans as ridge travel was no longer safe - solar on convex south slope and corniced ridge on north slope. We had two whumpfs in low angle terrain on southwest aspect. Skied a north facing steep slope - powder on top. At 2000m it turned to wet heavy snow. Lots of wet slides on solar aspects to size 2-2.5. I saw a report on facebook (no MIN report yet) of a wet natural slab avalanche on a solar aspect running to valley bottom in meachen (south purcells) on sunday afternoon. </p>
