WEATHER OBSERVATIONS
 HN24: HST: Sky: OVC Precip: S1 Temps: low 20s
 Ridgeline Wind: Light and Gusty from the NW
 Blowing Snow: L Snow Available for Transport: Large amounts
 Comments: Foggy and humid. Steady light snow from Ketchum to Stanley Basin that looked like it was having a hard time accumulating to much over a couple inches. Light wind gusting moderate on the WRV side and light/calm on the Stanley side @ 1400.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 1 Mouth of Lake Creek Today 1 L N W 6400 Same location just south of Lake Creek Rd that buried highway last year. These paths are full. I'd assume any loose wet cycle will put debris on the road.
 Comments: Poor visibility.
SNOWPACK OBSERVATIONS
 HS: Near mouth of spring creek, SW, 7200': 
 Upper Pack: 5-15 cm HN24 on thin MFcr (1/21)
15 cm DF on MFcr (1/18) 
 Middle Pack: n/o 
 Lower Pack: n/o 
STABILITY TESTS
 Stability Test Results: Hand shears showed well bonded storm snow on wests that lacked a crust. On southwest storm snow was well bonded to (1/18). Easier, planar shears just under delicate MFcr (1/21). No slab on top at this location to be a concern.
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)    
 Comments: Localized cracking in wind deposits from (1/22) south wind.
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
BOTTOM LINE
 Comments: Steady light snow is camouflaging wind affects from yesterday. I'd expect these pockets of low elevation slabs to heal quickly. North wind tomorrow may present another round of touchy slabs on exposed upper and middle south facing slopes.
