A heat wave has brought summer temperatures to the Rocky Mountains, and the wintry snowpacks are coming unglued.<\/strong> Numerous wet loose avalanches have been reported in the last several days, and as meltwater works its way deeper into the snowpack, the prospect of large wet slab avalanches grows more likely.<\/p>\n

On Thursday, Alta, Utah, recorded a high of 61\u00b0 F at its base area.<\/strong> Arapahoe Basin recorded highs of 51\u00b0 F at more than 11,000 feet and has not cooled below freezing the past two nights. High pressure and warm temperatures are expected to persist for the next seven days, raising the risk of a wet slab avalanche cycle.<\/p>\n
