Avalanche risk The Bottom Line

The avalanche hazard is LOW today.   Colder temperatures after several days of warm weather have helped to €œlock down € the surface of the snowpack.   Below this firm surface is a shallow and weak snowpack that holds little potential for avalanche activity.

Hazards associated with early season conditions continue to be the main problem to deal with in the mountains around eastern Turnagain Arm.  Exposed rocks and a variable crust will make travel difficult in avalanche terrain today.

Snowpack Discussion
Over the weekend we followed the development of our newest crust on the surface.  This thin crust exists at all elevations and in most areas has a layer of surface hoar sitting on top.  While this crust/surface hoar combo is not dangerous now, it will have our attention when a slab forms on top of it in the future.  Continue to check our observations page as we monitor the development of our snowpack. 

Weather
Mon, December 9th, 2013

The ridge of high pressure that brought spring like weather to the mountains over the weekend is breaking down today.   Ridge top temperatures are in the low twenties F this morning.  

A weak disturbance associated with a low pressure system to the Southwest will bring the chance of some light flurries through the day.   This will help to push the remaining areas of fog out of the lower elevations.   Winds will be light out of the West and ridge top temps will reach into the mid to upper twenties F.

As this high pressure ridge breaks down a series of low pressure systems will brush by well to the South of the area over the next several days.   This will translate to cooler temps, cloudy skies and low chance for precip until later in the week.
