Observer Comments
Recent "full conditions" storm with high winds and heavy snowfall.
Weather
Over 24 hours of high winds gusting to 45 mph from the SE with mixed grapuel, rhyme and fine snow. Visibility was often less than 50' and never over 1/4 mile during the storm. Just before dark on 4/4/21 the wind changed direction while snow was still falling to a gusty to 30 mph NE wind. Skies started clearing to the N NE just before dark. Gusty N NE winds continued through the night transporting snow. This has created a complex multidirectional wind loading situation.
Snow surface
Wind transported snow with loose graupel on some lowlying surfaces and in wind wells.
Snowpack
Fresh windblown snow on top of late season snowpack.
