I know…the dreaded ‘wet avalanche’ infographic… The snow/rain line, as of Tuesday evening, sits around 1800′ and looks to climb as high as 2,600′ by tomorrow. However, the rain has yet to begin, only the warm temperatures have set in. Rain is forecast to start falling late tonight with the heaviest period being tomorrow night. This rain-on-snow setup should begin to initiate a wet avalanche cycle at the mid-elevations (Below 3,000′) sometime tomorrow or tomorrow night.
At the upper elvations, above 2,500′, moist storm snow should begin to fall tomorrow and Thursday. We should see roughly 8-12″ by Thanksgiving with strong Easterly winds. As the snow piles up, we could see steep slopes avalanche naturally. In this case, human triggered avalanches will be likely.
Once again, check back in for Thursday morning’s bulletin.
Glide cracks are likely to widen with the warm weather and some of these may release and avalanche. Watch for, and avoid being under, cracks if you are thinking of heading to the Tincan Trees.
