Kernpunkte

A two-part storm system arriving today and lasting through tomorrow will increase the avalanche danger. West and northwesterly winds will form wind drifts on leeward aspects near and above treeline. Avoiding steep slopes with catchment zones and watching for signs of instability will minimize your exposure to this problem.

    Today, light snow coupled with strong winds will make for easy snow transport. This process will occur as the day advances, with fresh drifts forming on leeward aspects. Near and above treeline on specific south and east aspects, previous wind-drifted snow exists. The incoming additional load could cause these drifts to become more sensitive over time, which would result in a much larger avalanche.     Areas to expect rising concern are leeward catchment zones near rock outcroppings, beneath ridgelines, or mid-slope depressions. Dry snow will fall on many hard surfaces, making bonding difficult, especially above treeline.   Strong to extreme wind speeds can often behave unexpectedly and oddly. Because of this, don't assume anything and be adaptable to the changing conditions. Your situational awareness is one of the greatest tactics for avoiding danger in the backcountry today.

Avalanche Discussion

Here we go! Another round of winter weather is here. A winter storm warning is in effect until 4 pm PST Wednesday, above 2000 feet. Extreme gale force winds are the main takeaway. Be prepared for whiteout conditions and wind chills in the negatives for mountain elevations. These types of conditions can catch the unprepared off guard. Be prepared with all the essential survival equipment. Warm cloths/ Food & water/First aid/ Navigation tools/ Headlamp/Partner or someone who knows where you are going.   

Yesterday, forecasters surveyed snow and trail conditions out near Ash Creek Butte. Give it a look HERE.
