Highlights

Following a poor refreeze last night, warmer temperatures, light winds, and clear skies will mean wetter snow today. Lookout for wet avalanches on steep slopes as the day progresses.

    You can expect to see surface snow melt quickly as the sun comes out this morning and air temperatures climb. Strong winds may slow the process and limit the size potential of loose wet activity on more shaded aspects and at higher elevations. Areas near rock outcroppings, cliff bands, and tight rocky couloirs where the effects of warming are amplified will present elevated hazards. Wet sticky snow, rollerballs, pinwheels, and increasing boot penetration are all signs of surface warming and may foreshadow larger point-release avalanches. Be wary of overhead hazards today and be ready to retreat if the surface snow thaws causing you to sink deep into wet unconsolidated snow.

Avalanche Discussion

A poor refreeze last night means that melt water is continuously percolating through the snowpack, increasing the potential for wet snow instability. So far this spring this has been limited to wet loose activity. In the coming days as the run of warm days continues, we will be keeping an eye out for glide avalanches and wet slabs, these are unlikely for now, but worth keeping in mind.

Variable surface conditions and difficult access should remain top of mind for the backcountry enthusiast today. Hard and slick surfaces may require the use of mountaineering equipment such as boot and/or ski crampons. Experience and instruction are required to safely use these tools. In addition, keep in mind that parking may still be limited at trailheads and many access roads in the regions that sustained significant flood damage this winter.
