Points saillants

The avalanche danger is Moderate in the upper elevations today. New snow and wind has formed wind slabs on leeward slopes. These slabs will be easiest to trigger on steep terrain and up to a foot in depth. Warming and periods of sunshine will allow for shallow wet loose avalanche activity in very steep terrain below 9,000 feet. Due to the relatively small size of potential avalanches the danger is Low in the low elevations today.

    Strong westerly winds combined with anywhere from 2-6” of new snow helped to form new wind slabs. Field observations showed generally good bonding between the new snow and old surfaces yesterday. Despite this it will be important to pay attention in terrain with newly formed slabs and be on the lookout for shooting cracks and hollow sounds underfoot. Triggering a wind slab will become more serious when traveling above terrain traps such as cliffs, gullies and trees.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Snowfall has begun to taper off this afternoon. Expect lingering isolated snow showers overnight with accumulations in the trace to 1” range. Temperatures between 8,000 and 9,000 feet will dip into the teens overnight and rise into the high twenties to low thirties tomorrow. Winds will be out of the west and northwest at 15-20 mph. Expect partly to mostly cloudy skies during the day with periods of sunshine.As snowfall tapers off tonight, the likelihood of triggering avalanches will generally decrease. However, the possibility will remain for triggering small wind slab avalanches in the upper elevations tomorrow. Westerly winds will help to redistribute today’s new snow onto leeward slopes. Warming temperatures during the day combined with periods of sun will help make triggering wind slabs easier. The temperature/sun combo will also allow for shallow wet loose avalanches in steep sunlit terrain at all elevations. The avalanche danger will remain Moderate in the upper elevations and Low below 9,000 feet.
