This week's warm weather is triggering avalanches in the high country and flooding in the Valleys.
One killed a skier at Arapahoe Basin and another skier was seriously injured on Buffalo Mountain.
Experts say warm daytime temperatures heat the snow, which melts and percolates down through the snowpack. That creates an unstable slushy layer that can slide.
Meanwhile, minor flooding was reported in several Western Slope communities.
Grand Junction hit a record 94 degrees yesterday. Temperatures in the high 80s and low 90s were forecast for the weekend, melting the snowpack and swelling streams.

Meanwhile, Officials said Minnesota Creek began overflowing into local parks in Paonia yesterday.
