Old & wind drifted snow, where it exists, is thin & firm. Cross-loaded & Northerly facing slopes are holding pockets of snow deposited nearly a month ago. With new precipitation & gale-force winds expect these areas to develop deep hazardous wind slabs on the older ones.
A quick blast of snow, wind & cold has arrived for our forecast zone, finally... It could bring us 5 to 10 inches of new precipitation but will be driven by the gale-forced winds gusting to 105 in the alpine! There is no doubt this snow will be moving around the hills & finding its way into terrain features as deposits, likely sitting on slabs formed around Thanksgiving. With strong winds, storm slabs can become much thicker than estimated snow totals. As usual, these accumulations will need time to settle before safe conditions prevail.
A predominantly thin & scoured snowpack exists in the BWRA. Wind deposits on shady & Northern aspects range from 1 to 22 inches in the alpine & bare ground exists almost everywhere below 8800'. The new snow accumulations will make slopes above 35 degrees suspect for avalanches, as it sits upon stout wind & sun crusts. The BWRA will remain CLOSED due to lack of adequate snow coverage. The Bridgeport Avalanche Center will be monitoring the area & snowpack daily.
A Narrow Cold Frontal Rain system is currently underway in our area. This quick & windy snow storm could bring us some much needed moisture with accumulations of 5 to 10 inches in the higher mountains of the Pacific Crest. Winds will be strong from the Southwest changing to North as the storm moves across the slope. Gusts as high as 105 mph are forecasted! Single digit temperatures will be seen tonight, but a return to high pressure immediately following the frontal passage.
