It's way too hot, and without a significant refreeze of the saturated snow for well over a week now, dangerous wet avalanche conditions exist in the backcountry. Overnight low temperatures in the mountains stayed too warm overnight, in the mid to upper 40°F range, even at the highest elevations. Mostly clear skies mean that a thin crust likely formed on the snow surface due to long-wave radiational heat loss, but it is superficial and won't last long in today's sweltering heat. Today, you can expect to find a thin supportable crust in the morning with rough, dusty snow surfaces. The surface crust will rapidly soften during the day as temperatures soar in the hot sun, and the snow will become less supportable and punchy or sloppy.
The snow is so soft and saturated in many areas that you post-hole right to the ground if you hop off your sled when you're off the beaten path. While the melt-softened snow keeps the sled cool and is more fun to ride on than firm snow, the softer it gets, the more unstable it is. A saturated snowpack makes predicting the timing of wet avalanches hard because the snow softens and becomes unstable at different elevations and aspects at different times. Given the uncertainty inherent in wet avalanche prediction, your safest option is to avoid riding on or under steep slopes.

At 0500, the UAC Card Canyon weather station at 8700 feet reports 47°F and 42.3 inches of total snow. It's a sweltering 50°F at the Tony Grove Snotel, with 51 inches of total snow. On Logan Peak, winds are blowing from the west-southwest at 23 mph, with an early morning gust of 44 mph. It's 44°F on Paris Peak at 9500 feet, and the winds are from the southwest, blowing 19 to 25 mph. It will be sunny in the mountains today, and temperatures at the highest elevations in the Logan Zone will reach around 57°F, with moderate winds blowing from the west-southwest. Overnight, temperatures will drop into the mid-30°F range, but will stay well above freezing in most upper-elevation areas again. Temperatures tomorrow will be 10 to 15 degrees cooler than today's, and they are likely to drop below freezing tomorrow night for the first time in over a week.

Coverage is still good at upper elevations in the Central Bear River Range, though the snow is rough, dusty, and debris-covered.
Ski resorts in the Wasatch report both natural and human-triggered loose and wet slab avalanches with yesterday's summer-like weather. In the last few days across the Logan Zone, we've observed numerous natural wet avalanches caused by the extreme heat wave. Monday, I could see evidence of fresh wet avalanche activity in north-facing terrain off Logan Peak in Mill Hollow and Drop In, Drop Out in lower Logan Canyon, way above Zanavoo. Yesterday, there were a few more small natural wet avalanches visible in the Wellsville Mountain Wilderness.
A natural wet slab avalanche occurred Tuesday in the Ogden Area backcountry...
