Highlights

Wet snow avalanches will become possible as daytime warming occurs today. Potential thunderstorms this afternoon could further increase any wet snow instabilities. If the snow surface becomes wet, deep, and unsupportable, move away from avalanche terrain.

    Surface crusts this morning will soften as daytime warming occurs exposing areas of deeper wet snow. Roller balls and pinwheels will indicate that the snow surface is losing strength and that larger wet loose avalanches could soon occur. If the snow becomes, deep, wet, or unsupportable, move away from steeper avalanche terrain.

    Increased cloud cover and mostly above freezing temperatures overnight could decrease the overnight refreeze of the snow surface in some areas. Areas with increased cloud cover could spread wet snow development to more aspects earlier in the day. Slightly cooler temperatures are expected today with increasing clouds and the chance for afternoon thunderstorms. Look for signs of changing snow surface conditions while traveling in the backcountry.  Keep in mind that even small avalanches can have increased consequences in exposed terrain.

Avalanche Discussion

March and April's record-setting heat and strong sun have caused dramatic snowmelt on all aspects and elevations throughout the forecast region. Large areas of bare ground are present on all aspects below 8,000' as well as on southerly aspects at all elevations. Northerly aspects offer better snow coverage, but many obstacles like dirt, rocks, stumps, and logs have melted out on these slopes as well. Areas with available snow and minimal walking are limited to the highest trailheads in our forecast area. Long, sliding falls remain a hazard in areas with frozen snow surfaces.
