Conditions Summary
HAZARDOUS AVALANCHE CONDITIONS EXPECTED
.
Continued heavy snowfall with strong winds through today will combine to increase the avalanche hazard to HIGH DANGER this afternoon.
Travel in avalanche terrain is NOT recommended.
.
Independence Mine Snotel is reporting 8″ of new snow overnight and the Marmot snow stake also shows approximately 8″ of new snow. This comes out on the shorter end of yesterday’s weather forecast for 8-13″.
At 4:00am this morning the Recreational Forecast is calling for 9-18″ of new snow today, and this morning at 8:00am the hatcher pass point forecast is calling for 11-16″ of snow today.
.
The storm will start cool and warm up creating an upside down, unstable snowpack, which is also sitting on weak, basal layers near the ground. Warmth at the end of the storm could mean rain on snow at mid to lower elevations.
Expect natural and human triggered avalanches to be likely, and for remote avalanches to be possible. Avalanches will be full depth, fail at the ground, and be large enough to bury, injure or kill a person.
