Highlights

Human-triggered wet avalanches remain possible at middle to lower elevations.  Monitor surface warming as you travel through terrain today.  Avoid steep slopes where snow is wet and mushy.

Avalanche problems

    Size
    1–2

    Human-triggered wet loose avalanches remain possible on all aspects near treeline and below. Lower elevations may not have received a solid overnight freeze. Below treeline terrain may also experience light rain showers today.  Although unlikely. wet-loose avalanches may trigger a more dangerous wet-slab in isolated locations.  Alpine terrain will likely remain firm due to near freezing overnight temperatures and gusty winds.

    If snow becomes mushy or unsupportable, avoid steep slopes.

    Wet slab avalanches are becoming increasingly unlikely.  There have been no wet slab avalanches observed in the forecast area since the recent rain on snow event followed by multiple days of non-freezing temperatures. Lower elevations have a chance of light rain showers today.  Near treeline terrain and below may still have not received a solid overnight freeze leaving the potential for a wet slab avalanche to occur in isolated locations.  This would be a low likelihood, high consequence scenerio.  Alpine terrain of all aspects will likely remain colder with firm surfaces today.

    Avoid steep slopes if deep, unsupportable snow is encountered.

Avalanche Discussion

Temperatures this morning at Sonora Pass and Leavitt Lake Snotel sites still did not reach solid freezing temperatures.  Non-freezing temperatures have been occuring for most locations since the recent rain on snow event.  Last week heavy rains fell on 2-6' of recent snow and a buried faceted weak layer.  After the rains, evidence of natural wet-slab activity was expected but none were observed in the forecast area. Numerous natural wet loose avalanches were observed just after the rain storm up to D2+ in size on all aspects.

Snow surfaces in middle and lower elevations have remained wet and mushy making human-triggered wet avalanches possible in steep terrain.  Wet slab avalanches are increasingly less likely today but the recipe of reactive faceted weak layer and overlying wet snow may still be present in isolated locations.  Human-triggered wet loose avalanches remain possible near and below treeline.

Light rain showers may occur today at lower elevations and up to an inch of snow is forecasted along the crest for today and tonight. Alpine snow surfaces have remained firm on north aspects recently and all aspects above treeline are expected to stay firm and locked up today with cooler temps and gusty winds. Most locations are expected to receive freezing overnight temperatures tonight.
