There is a possibility of small loose wet avalanche activity in the afternoon hours. Without cloud coverage we can expect rapid warming of snow surfaces leading to unstable steep slopes. There is spring corn riding to be had out there today.
The large snow accumulations we received over a week ago has shrink-wrapped itself to our slopes. Rapid melting is occurring daily & temps are just below freezing at night giving us an unsupportable crust before noon. Corny surface snow is available in the afternoon hours & loose wet avalanche activity is also possible. There are wind slabs on Northeast aspects from strong winds on Thursday that will require caution.
This weeks observations come from all over our region including: Stanislaus NF, Virginia Lakes, Hoover Wilderness, the BWRA, & Twin Lakes. The avalanche activity from early in the week had settled down & we are experiencing spring-like conditions. We had our first Public Observation of the season from the other side of Sonora Pass. The snowpilot graph shows us a problematic layer of Graupel mid-pack. Graupel can be a serious layer of concern soon after a storm. The large grain size & unconsolidated structure can act like ball-bearings within a snowpack. Thank you very much for the info! Other observations key us into wind slabs that have formed & rapid melting is taking place. Numerous Large Old growth trees were toppled by the snowload & strong winds from our recent storm.
