Details

Conditions In Old Ski Bowl, Southside of Mount Shasta:

  • DATE: February 14, 2020 (20200215)
  • TIME: 1430 hrs
  • OBSERVER: Sorenson
  • LOCATION: Old Ski Bowl
  • SKY CONDITION: Clear
  • PRECIPITATION TYPE/RATE: None
  • BLOWING SNOW: None
  • AIR TEMPERATURE: 37 deg F
  • SURFACE PENETRABILITY: 2-5 inches (5-12 cm) 
  • WIND: Calm - Light SE at 9,600 feet
  • HEIGHT OF SNOWPACK (HS):
    • 7,300 feet ~ 65 inches (165 cm) 
    • 8,600 feet ~74 inches (190 cm)
    • 9,600 feet ~65 inches (165 cm)

Snow surface conditions are smooth, however variable at all elevations. Below treeline snow surfaces are mostly moist and soft.  Above 9,000 feet, snow surfaces transition to a mix of breakable crusts with pockets of soft snow.  A small D1 loose wet avalanche has slid in Powder Bowl on Green Butte's southeast aspect. This natural avalanche (WL-N-R1-D1) likely released today during the warm afternoon temperatures. Intense solar radiation often will weaken snow surfaces. As we move further into spring and the sun tracks higher in the sky concern for loose wet avalanches increases.
