COPPER RIVER HIGHWAY AVALANCHE HAZARD
Outlook: The hazard should remain about the same through the week.
BACKCOUNTRY AVALANCHE HAZARD
Above Tree Line: MODERATE trending to CONSIDERABLE Use increasing caution around steep wind loaded western slopes.
Tree Line: MODERATE Use caution around steep slopes.
Below Tree Line: LOW Use caution around steep slopes in the afternoon.
We received an inch and a half of water last weekend with light east wind. Diurnal temperature swings caused the freezing line to fluctuate between sea level and our local peaks. This caused several small avalanches during the heat of the day. Tuesday and Wednesday brought a few snow showers with light to moderate east winds. Wednesday, a snowboarder triggered a medium sized slab avalanche on a western slope above tree line. Clear skies brought strong sunshine Thursday and Friday. Diurnal temperatures continue.
Expect a mix of snow and rain through the week. Models suggest a half inch of water Sunday. The freezing line has started at sea level this morning, but should climb through the day. Moderate to strong east wind will load western aspects, especially above tree line. Precipitation should decrease Monday. Diurnal temperature swings will continue to cause some instability during the afternoons. Avalanches should be small and are not expected to affect the highway. Backcountry users should use caution around steep slopes in the afternoon.
