""Don't entirely trust any of these slopes until temperatures dramatically cool down. Each day, the sun climbs higher in the sky, and the oppressive heatwave sends meltwater deeper into colder snowpacks.""
""Wet slabs release when meltwater reaches and pools at these weak layer interfaces. The exact timing is hard to predict, but our best guess is that it's happening now.""
A heat wave has led to high temperatures in the Rocky Mountains, causing snowpacks to destabilize. Wet loose avalanches have been reported, and the likelihood of large wet slab avalanches is increasing. Alta, Utah, recorded a high of 61°F, while Arapahoe Basin reached 51°F at high elevations. Warm temperatures are expected to continue, raising avalanche risks. Avalanche forecasters are monitoring the snowpack for weak layers becoming damp, with uncertainty about when critical liquid levels will be reached. Recent observations include naturally released wet slab avalanches.
