Good morning, this is
Under cloudy skies, light snow has just started to fall in the mountains.† Overnight, the westerly winds averaged 25 to 35 mph across the highest peaks, with gusts to 50.† This morning, the winds are in the process of shifting to the northwest and have decreased into the 10 to 20 mph range at most locations.† Temperatures are in the 20ís at mid elevations, and the teens along the ridgelines.† Most old snow surfaces are rough supportable wind or sun crusts, though several inches of soft recrystalized powder on northwest through northeasterly facing slopes provides good riding conditions on untracked slopes.
Snow and Avalanche Discussion:
The only activity reported Friday was a very few damp sluffs on steep, sunny slopes and one tired old wind slab that cracked, but didnít move.†
Today, with the addition of a small shot of new snow, sluffs on steep northwest through northeasterly facing slopes could become large enough to be a concern to skiers, boarders and snowshoers.† On many of these shady slopes, the new snow will be landing on sugary, near surface facets sitting on a hard bed surface.† Once a sluff gets moving, it could entrain more snow, and run further and faster than expected on long, continuously steep slopes or in gullies.† A few perched wind slabs or cornices could also crack out beneath the weight of a person, and in the wrong terrain, send them off a cliff or tumbling down a long steep slope.
Bottom Line for the
The avalanche danger is generally LOW today, with a MODERATE danger on steep, upper elevation northwesterly through northeasterly facing slopes, where long running sluffs large enough to knock a person off their feet could be triggered. †It may also be possible to trigger a few old wind slabs or cornices, which could send you for a ride in the wrong terrain. The consequence of triggering one of these small avalanches is much less for those on snowmobiles.
A weak cold front will bring light snow to the mountains today, with 3 to 5 inches possible.† Another inch or two may be added tonight as snow showers linger into the evening under a northerly flow.† Temperatures today will be near freezing at 8,000í and in the upper teens at 10,000í.† The northwesterly winds will continue to decrease, into the 10 to 20 mph range at most stations.† Sunday will be partly cloudy and cool with very light winds.† After a rapid warm up on Monday, a small storm looks to be on tap for Tuesday night into Wednesday, with a stronger storm forecast for around next weekend.
