COPPER RIVER HIGHWAY AVALANCHE HAZARD
Outlook: The avalanche hazard may increase this weekend.
BACKCOUNTRY AVALANCHE HAZARD
Above Tree Line: CONSIDERABLE Avoid cornices and steep western slopes.
Tree Line: MODERATE Avoid large paths.
Below Tree Line: LOW
Previously, we had no snow up to 1000 feet and a shallow variable snowpack in our local upper mountains. We received about 5 inches of water last week, with the freezing level fluctuating between sea level and our local peaks. This translated into a couple inches of snow at sea level, a foot or two at 1500 feet, and about 4 feet in the upper mountains. Moderate east winds loaded western aspects. Temperatures have since been diurnal with strong sunshine Monday. Today brought light precipitation, increasing this afternoon as temperatures rose above our local peaks.
Expect precipitation to continue with the freezing line above our local peaks through Thursday. Weather models suggest another 1 ½ inches of water, though models have been inconsistent. Small loose snow avalanches are likely, while larger avalanches are increasingly possible. Activity is not expected to affect lower elevations. The freezing line may come down briefly at night, but a warmer storm is expected this weekend. The avalanche hazard may increase as we move into another spring thaw.
