COPPER RIVER HIGHWAY AVALANCHE HAZARD
Outlook: The avalanche hazard should remain the same.
BACKCOUNTRY AVALANCHE HAZARD
Above Tree Line: MODERATE Use caution around sun baked aspects.
Tree Line: LOW
Below Tree Line: LOW
We have received a good amount of water so far this month, with the freezing line fluctuating between sea level and above our local peaks. Medium to large slab avalanches have occurred on wind loaded western slopes above tree line. The lack of snow in lower elevations has kept debris from reaching potential run outs. Clearing skies now bring diurnal temperatures, increasing the hazard during the heat of the day. No snow remains below 1000 feet, about 2 ½ feet sits at 1500 feet, and several variable feet exist in the upper mountains.
Expect dry weather with diurnal temperatures through next week, though confidence decreases with distance. Clear skies at night will bring temperatures below freezing and promote snow stability. Strong sunshine in the afternoon may cause small loose snow avalanches, but could also trigger cornice and glide crack failures. Possibilities increase during the heat of the day.
