Dusting of snow in north side of mountains to below 3,000’ Once above 4,000’ snow patches more consistent on road in northern sheltered locations. 6,200’ @ 1:30pm solid coverage on mountains. Strong Northeast to northwest winds. Lots of wind transport. BP ranging from 4” to 20”. Very dependent on wind loading and aspect. Average depth 4” to 12”. Snow appeared to have come in lighter for first round Monday morning than heavier for the bulk of the storm in the afternoon to evening. Significant wind loading on northerly aspects. At time of observation though winds were northerly topographic influence was causing loading on north aspects as well as southern aspects. This is in essence the first storm of the season. Sinking down to ground or obstacles. Low tide early season conditions. We’ll need more of this to really open up the back country. Resist powder fever and wait for more snow.
