Danger Rose Tutorial

The BOTTOMLINE for today in the Abajo and La Sal Mountains is an avalanche danger of Considerable, with pockets of HIGHon steep NW-N-NE aspects at and above treeline. Avoid crossing the runout zones of avalanche paths, as there is plenty of snow for transport and there is still a potential for natural avalanches. If heading out in the backcountry today, bring plenty of warm fluids and clothes...more than likely just getting there will be an epic.


CURRENT CONDITIONS

Artic air has settled over the forecast area in the wake of a storm that blanketed the La Sal and Abajo mountains with almost two feet of snow. Pre-Laurel Peak is registering a temperature of -12F at 7:00 am, the Geyser Pass TH is at -2.0 F while down in the Abajos it is currently 2.5F. Strong southerly winds during the storm has transported massive amounts of snow onto northerly aspects. The winds have certainly died down since the frontal passage with Pre-Laurel Peak's weather station reporting almost no wind for the past 6 hours. If you can make it to the trailhead and brave the cold air, there is great skiing and riding conditions...of course there is a significant avalanche hazard to deal with as well.


RECENT ACTIVITY

There was limited visibility during December 30th's tour, the only avalanche to note was the last road cut on the Geyser Pass road. There was plenty of collapsing and settling on the tour, and test slopes produced propagating cracks in the new snow. The La Sal's picked up almost 2" of snow water equivalent, while the Abajos near 3". With this much new weight, combined with wind, another spectacular natural avalanche cycle occurred and there will be areas that are waiting for the stress of a snowmobiler or skier to release.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Cold air will keep the new snow brittle and reactive. Strong winds will have deposited deeper wind pillows lower in the starting zone than usual.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Although our snow pack is deeper than average, it has plenty of weak layers sandwiched within it. Buried surface hoar in sheltered northerly locations while old wind slabs are overlying faceted layers in wind affected locations.


MOUNTAIN WEATHER

Today: Snow. High near 9. Wind chill values as low as -10. North northwest wind between 5 and 10 mph, with gusts as high as 20 mph. Chance of precipitation is 80%.
