OK the party is on. Prepare yourself for a real Sierra Stomper. A cold Pacific storm originating in the GLA will dig along the West Coast Friday then slam into the Sierra Saturday – Monday. This system will pick up a moderate Atmospheric River along the coast. Strong winds and cold temps will come with this weather package. The upper elevations of Mammoth Summit could see intense snowfall rates up to 3 – 4″/hr! I am expecting a possible 3+ feet at the Main Lodge and 4+ feet over the Summit by Monday. Travel over Sierra passes will be treacherous, with downright Blizzard conditions at times (Saturday thru Saturday night). For the Owens Valley, snow levels start at 6K feet Saturday, lowering 3K feet Sunday, then dropping to 2K feet early Monday…DMATT
