Recent Observations:
Yesterday provided clear and calm conditions across the region. The cold temperatures and scattered showers gave way to sunny skies and a warming trend by mid-afternoon. Wind remained light out of the north. Around one to two inches of low-density snow fell across the Mount Shasta area.
Yesterday's observations came from the Gray Rocks area. The road to Castle Lake is still closed, with one very narrow lane plowed to the Methodist camp. North, east, south aspects held one to inches of new snow on top of a firm surface crust. North facing terrain remained slightly softer, with a less obvious crust underneath the new snow. East facing terrain still held some variable surfaces due to wind effect. Slight cracking was observed between ski tracks. Some old avalanche debris was still visible on north and east facing aspects. Beside the cracking, no significant signs of instability or recent avalanche activity was observed. Snow depth in this area was over 150 inches.

Mountain Weather:
A brief period of calm weather will continue through this morning. Cold temperatures and light winds are expected through midday. This afternoon, a large storm system off the coast of the Oregon-California border will hit land. This storm will begin to impact the Mount Shasta area by late afternoon. Moderate to heavy snowfall is expected for much of Siskiyou county from Monday evening through Tuesday afternoon. The previous winter storm watch has been upgraded to a winter storm warning, and extended through Wednesday morning. This storm is expected to bring one to three feet of snow as low as the I-5, impacting travel in the area. Around two to four feet of snow is expected at treeline on Mount Shasta. Upper level winds will also elevate with this storm. Southerly winds will be moderate to strong below treeline, and extreme above treeline.
