Spring Avalanche Statement -Spring in northwest Montana brings a mixed bag of weather. Snow, rain, sun, and everything in between can occur all in one day. This can greatly affect avalanche conditions. It is essential to pay attention to changing conditions as these changes can happen rapidly and stability can also deteriorate fairly quickly. Avalanches still happen in the spring and it is important to not let your guard down.

Light snow overnight, combined with wind, has elevated the avalanche danger. This new and windblown snow is being deposited onto a crust which will act as a slippery bed surface for wind slabs and storm slabs. The avalanche danger is MODERATE above 5000'. Evaluate all wind loaded terrain and areas favored by snowfall before committing to a slope. Today is the last daily advisory issued by the FAC for the season.

Cool overnight temperatures have formed a thin surface crust at all elevations. This crust will weaken throughout the day as temperatures warm and especially if forecasted precipitation enters our area sooner than expected. At upper elevations there exists a layer of unconsolidated surface snow that is susceptible to triggering a larger wet loose avalanche. The avalanche danger is LOW. Pay attention to changing snow surface and weather conditions today while continuing to practice safe backcountry travel techniques.

Heightened wet avalanche concerns exist due to continued warm temperatures and rain on recent, unconsolidated snow. The avalanche danger is MODERATE above 6000 feet where human triggered avalanches are possible. Pay attention to changing weather conditions today. More rain than anticipated could result in deeper instabilities and increase the potential for larger wet avalanches. Below 6000 feet the danger is LOW.

Warm temperatures with rain and snow showers today will raise the avalanche danger to MODERATE at all elevations.   The warm temperatures and rain may weaken the surface snow, making it possible to trigger a loose wet avalanche. Pay attention to changing conditions.  If the sun does make an appearance, expect it to increase instability.

Warm temperatures and clouds are forecasted for today. The avalanche danger will be LOW today at all elevations.  The danger may rise to MODERATE if the sun does break through. Warm temperatures may weaken the surface snow, making it possible to trigger a loose wet avalanche. Pay attention to changing conditions.  If the sun does make an appearance, expect it to enhance the impacts of the warm temperatures leading to increased instability.

Today we can expect clearing skies and above-freezing temperatures by this afternoon. The avalanche danger will begin at LOW but then rise to MODERATE at all elevations as the day progresses. Sunshine and warm temperatures will weaken the surface snow, making it possible to trigger a loose wet avalanche. Pay attention to changing conditions and move to more shaded terrain if slopes facing the sun start to become unstable.

Light snow overnight and through today is being deposited onto a surface crust. Winds have and will transport this low density snow and form thin fresh wind slabs in areas favored by snowfall. The avalanche danger is LOW. Continue to practice safe travel techniques and evaluate all slopes that have been favored by new snow or wind loading.

Today's cloudy cool conditions will minimize natural loose wet avalanche activity but there remains a chance to trigger one of these slides. At upper elevations a thin surface crust caps a layer of unconsolidated snow. At low elevations the surface crust is unsupportable or non-existent. The avalanche danger is LOW. Pay attention to changing snow surface conditions and avoid consequential terrain if you or your machine start to sink below the snow surface into moist unconsolidated snow.

Overnight, a weak refreezing of the snow surface has resulted in another day with a loose wet avalanche problem. Recent new snow in the upper elevations has yet to consolidate and could be susceptible to triggering today. The avalanche danger is LOW.
