Snowpack synopsis
Increasing snowfall overnight and early Wednesday was accompanied by brief warming and increasingly strong winds.along with slowly stabilizing but still unstable wind slabs from Monday, this has produced a locally high danger on lee slopes with considerable danger elsewhere.
Thursday, Thursday night
Increasingly heavy snow or rain is expected Thursday, along with very strong winds and significantly rising freezing levels. This weather should produce a substantial increase in the danger, with extreme danger expected to develop Thursday afternoon and evening before slowly decreasing Thursday night. Widespread natural or human triggered avalanches should become certain Thursday afternoon, along with an increasing potential for some large destructive Avalanches. Back country travel in avalanche terrain should be avoided, and travel confined to lower angle terrain well away from avalanche path runouts.
Lowering freezing levels should allow for a gradual decrease from extreme danger later Thursday night and early Friday.
Backcountry travelers should be aware that elevation and geographic distinctions are approximate and that a transition zone between dangers exists. Remember there are avalanche safe areas in the mountains during all levels of avalanche danger.contact local authorities in your area of interest for further information.
