PROFESSIONAL OBSERVATION FORM
 Start Date: 03.28.19 Name: Lundy Operation: SAC
 Drainage/Route:  Copper Observed Terrain:  6900-9000', most aspects Zone/Region:  Banner Summit
WEATHER OBSERVATIONS
 HN24: HST: 25-30 Sky: BKN Precip: Temps:
 Ridgeline Wind: Moderate from the S
 Blowing Snow: L Snow Available for Transport: Large amounts
 Comments: 25-30cm settled HST since 3/26. Bottom 15-20cm of the HST was moist below about 8500', with a thin crust present mid HST in some places. A few sunny periods with enough solar radiation to affect sunny slopes. MOD south winds at the top were moving a bit of snow with some fresh drifting. Overall, temps remained relatively cool, especially at upper elevations. A brief squall moved in around 1400 with about 20min of graupel and S1-2.
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: N, 7850': HS 285cm 
 Upper Pack: 25-30cm of HST since 3/26. As described above, bottom 15cm of the HST (what fell yesterday morning) was moist to wet at all but the highest elevations. Latest round of precip overnight was dry. Surfaces became moist at mid and low elevations and on upper elevation solars. Low and mid elevations have wet snow or a thin, barely frozen MFcr below the HST. Upper elevation S had a supportable, stout MFcr below HST. Upper elevation shady remains dry below HST.

AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wet Loose

Layer/Depth:
20-30cm

Likelihood of Triggering
Sensitivity:
Reactive

Spatial Distribution:
Widespread
Terrain
  Primary Concern Comments: Wet snow problem really only existed at low elevations. Felt confident you could have got a wet sluff moving on a slope >40* (based on pushing on ~35*). Wet snow instability was primarily within the HST but easily could have gouged down into old, wet snow below.
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
30-50cm

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Isolated
Terrain
  Problem 2 Comments: Saw a number of wind slabs and drifts at the top of copper. They were quite dense and some were up to 50cm thick. Some stomping around on a few steep rolls and along the ridge didn't produce any cracking.
STABILITY TESTS
 Stability Test Results:
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): Danger seemed less than forecast. MOD at low elevations for wet, MOD at upper for wind. Mid elevations seemed LOW.
BOTTOM LINE
 Comments: Any hopes of a spring powder day were dashed by moist nature of the lower HST. Ski conditions were quite funky.
