Kodiak spring corn skiing seasons is here and the long sunny days are making some of the steep South faces prone to wet avalanches You can see some wet slide activity on steep Souther aspects.Large wet slides are already ripping loose on souther slopes in the Devils prongs and behind Bells Flats. We had some rain and snow over the weekend that just added more weight and water to the snow surface. If it gets cold enough it will crust up and then thaw and corn up in the afternoon sun. This is typical of spring Snow pack in Alaska so here is a reprint of the Turnagain pass advisory
The overall avalanche danger is MODERATE this morning and will rise to CONSIDERABLE on steep Southerly facing slopes this afternoon and evening. Wet slab and wet loose avalanches will be likely to trigger and natural avalanches will be possible as the sun heats up and softens Southerly aspects. Paying attention to aspect and time of day are crucial. Watch for changing conditions. Avoid travel on or under cornices and give glide cracks a wide berth.
***On steep Southerly slopes with a thin snowpack, such as where rocks are protruding the danger could trend towards HIGH = natural wet avalanches likely, human triggering very likely. Avoid travel in Southerly avalanche terrain in the afternoon and steer clear of runout zones.And terrain traps
