Regions: Mt Hood.

Isolated pockets of shallow wind slab may exist above treeline on lee slopes. Otherwise be cautious when travelling on slopes with an exposed slick surface crust due to fall hazard. 

Detailed Forecast

Cloudy skies with very light rain or snow developing Sunday afternoon should not change the low avalanche danger at Mt. Hood. 

Isolated pockets of shallow wind slab may exist above treeline on lee slopes. Otherwise be cautious when travelling on slopes with an exposed slick surface crust due to fall hazard. Early season hazards still exist. Many creek beds have still not filled in for the winter.  

Snowpack Discussion

Light to moderate rain Thursday night and Friday began to soften surface crusts on most slopes. On Saturday, temperatures cooled and winds eased but there was little new snow at the tail end of this most recent system. 

Several rain and freezing rain crusts are sandwiched in the upper snowpack depending on elevation. Current observations do not suggest these layers to be reactive.

Observations

NWAC pro-observer Laura Green was in the Bennett Pass area of the White River drainage on Saturday up to 6100 ft.  Laura found challenging travel conditions with a surface crust of variable strength and no notable layers of concern in the upper snowpack.  No signs of new avalanche activity was observed.
