Avalanche Problem 1: Normal Caution
Steer clear of cornices, both above and below and be cautious of loose wet sloughs. Otherwise exercise normal caution:
- Carry a beacon, shovel, and probe and know how to use them.
- Create a travel plan; stick to your travel plan.
- Actively look for evidence of instability while on the snow.
- Communicate well within your group. Expose only one person at a time to avalanche terrain.
Keep away from steep slopes with rime ice above. An ice axe, crampons, and helmet are mandatory if venturing above treeline, but remember self-arrest may be impossible.
Temperatures have ranged from 37 to 49 degrees in the last 24 hours near 7,600 feet. Winds have been light and northwesterly.
Expect to encounter a variety of surface conditions: rain runnels; textured snow; icy ridgelines and morains. Sun exposed aspects host the best conditions for skiing.
The infamous crack creeping across Broadway has not shown notable signs of growth.
Warm temperatures have been causing cornice failures along ridgelines of Middle Peak above Castle Lake. A small loose wet slide was skier triggered on a steep, sun facing aspect.
Weather and Current Conditions
High pressure continues to deliver mostly sunny weather, temperatures in the high 40s, and calm to light winds.
Tomorrow a closed low system will graze the area bringing a slight chance of precipitation and snow levels above 6000 feet.
A front moving in Friday looks to bring over an inch of precipitable water and falling snow levels.
