State of the Snowpack for 2/29/2020 - 3/6/2020

Dates of the Week: 
2/29/2020 to 3/6/2020
Avalanche Problems: 
General Snowpack Structure: 
  • Gale force NE winds scoured many near and above treeline areas back down to pre-storm snow surface.
  • Pockets of lingering settled storm snow below treeline on shaded northerly aspects, snow surface wetting in some areas.
  • Reestablishment of diurnal melt-freeze conditions on solar aspects with upper elevation E aspects remaining in a transitional state between recent storm snow and consolidated melt-freeze.
  • No problematic or persistent weak layers.
Weather Events: 
  • Storm event March 1-2 with 3 to 13 inches of low density new snow. Sierra Crest in the northern portion of the forecast area favored.
  • Gale force NE wind event immediately following the storm with ridgetop gusts to 126 mph.
  • High pressure for the rest of the week with well above average air temperatures at elevation Wed-Fri.
