West Slopes Central
Pericolo valanghe
In sintesi
With low danger avalanches are unlikely but not out of the question. On Monday, small wet avalanches may occur with warming where previously dry snow exists. We may get enough precipitation for an increase in avalanche danger on Tuesday.
Avalanche Discussion
On Monday, there’s a slight chance for loose wet avalanches. Cloud cover and a 6,000 - 7000ft freezing level may cause warming on all aspects. Watch for moist surfaces and rollerballs forming on slopes that were previously dry, especially northwest through north through east aspects at mid to upper elevations. On sunny slopes, the chance of these avalanches has decreased after many days of warm temperatures that melted snow surfaces.
The last wind slab and wet loose avalanches were reported on Thursday. Isolated features at shady upper elevations may still harbor wind drifted pillows of snow. Triggering an avalanche on them is unlikely, but not impossible. The past week of warm temperatures and high pressure has transitioned surfaces on south aspects to thick crusts.
Widespread surface hoar and near-surface facets have been found in neighboring areas topping the snowpack in the last few days. Be aware of these persistent weak layers as they may get coated with snow later this week- but hopefully, warm temperatures and rain will destroy them first.
Overall, we have a substantial early season base of 40-60 inches. Snow lines in the West Central zone are averaging 2500 - 3000ft. Remember that it is still early season and there are plenty of obstacles such as hidden logs, rocks, streams, and variable snow conditions at lower elevations to stay alert for.
During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources. Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
