Recent snow combined with wind continues to load upper elevation leeward aspects. Look for obvious signs of instability such as shooting cracks, whumpfing or hollow sounds. Due to the lack of early season observations carefully evaluate all slopes before recreating on any slope. Remember that if there is enough snow to ski or ride, then there is enough snow to avalanche. We will continue to update information without hazard ratings as conditions warrant until we receive/collect more snowpack data.

Snow showers since last weekend amounted to total snow depths across the area ranging from 17 to 40 inches. Recent snow combined with wind, low coverage, and uncertainty in conditions warrants careful evaluation before recreating on any slope. Remember that if there is enough snow to ski or ride, then there is enough snow to avalanche. We will continue to update information without hazard ratings as conditions warrant until we receive/collect more snowpack data.

It feels a lot more like winter with the snow-level inching toward the valley, and continued accumulation in the mountains. It's time to check your gear, put fresh batteries in your beacons, and start thinking about avalanches. A great way to dust off the cob webs is to join us for one of our upcoming avalanche awareness presentations. See upcoming events here.

The Northern Rockies Snow and Avalanche Workshop was a great success. Thanks to all of our supporters, partners, and, of course, the amazing work of the Friends of the Flathead Avalanche Center (FOFAC). As snow begins to accumulate in the mountains, we will begin to publish snowpack and avalanche information.

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.

Cooler temperatures overnight allowed the snow surface to re-freeze. The avalanche danger will start as LOW, but rise to MODERATE as the day progresses. In addition to increased potential for loose, wet avalanches later in the day, pay attention to slopes that could produce more destructive avalanches from cornice fall or glide cracks. Also, consider the lingering possibility of wet slabs before committing to steep, rocky, and exposed terrain.

Temperatures will slightly cool today, but instability in the wake of yesterday's heat wave will persist. Heat and sun weakened cornices, moist surface snow, and wet slab/glide avalanche problems due to free water in the snowpack will linger ahead of a substantial re-freeze. Natural and human triggered loose, wet avalanches are likely. The avalanche danger is CONSIDERABLE above 5000 feet. Choose conservative terrain to recreate in, and steer clear of overhead hazards like cornices, glide cracks, and run-out zones.

Unusual conditions breeds unusual avalanches. Expected temperatures of 25 degrees above normal today are unusual for early April. This combined with no refreeze overnight will create dangerous avalanche conditions today. Expect natural and human triggered wet, loose avalanches on all aspects. Cornice fall could also trigger large avalanches on the slopes below. Destructive wet slab avalanches could also become a problem.  The danger is CONSIDERABLE and could even rise to HIGH.

Today's well above normal temperatures and sunshine, combined with a poor refreeze of the surface snow, will create wet avalanche problems and dangerous conditions as the day progresses. Wet loose avalanches should be expected on all aspects. This unusual warming will weaken recently formed upper elevation wind slabs along with cornices. Cornice fall could trigger large avalanches on the slopes below. The danger will rise to CONSIDERABLE above 5000 feet and MODERATE below.

New snow overnight, combined with moderate to strong winds, has formed fresh thin wind slabs on upper elevation slopes. These slabs have been deposited onto a crust and will continue to form with today's forecasted winds. Recent warm temperatures have weakened cornices across our advisory area and should be given a wide berth. The avalanche danger is MODERATE above 5000 feet on steep wind loaded terrain.
