Tuesdays wet flurries will bring all forms of precipitation. Be prepared for snow or freezing rain depending on elevation.
As forecasting period progresses natural activity of storm slabs will taper but they will remain possible to human triggering.
Up to 20 cm precip and strong SW winds are forecast by Tuesday evening. This will create wind effected fresh storm slabs that could step down to deeper layers.
Freezing levels are is forecasted to rise to 1800m Tuesday. Precip will fall as rain or snow depending on elevation. Steep terrain below treeline will see wet loose activity. Watch for signs of pin wheeling.
Tonight: Wet flurries, 5-10 cm. Mod gusting to strong SW winds. FL 1600m
Tue: Cloudy with wet flurries, 15 cm. Mod gusting extreme strong SW winds. Alpine high -1. FL 1800m.
Wed: Cloudy with sunny periods. Light gusting strong SW winds. Alpine high -3. FL 1500m.
Thur: Cloudy with sunny periods. Light gusting strong SW winds. Alpine high 0. FL 1600m.
Below 1600m surface snow is moist down 50 cm. In alpine and treeline extreme SW winds and warm temps have pressed surface snow and continue to build new windslabs. This overlies old windslabs and the March 3 rain crust. Feb 15 crust down 60-100 cm exists up to 2000m. Lower snowpack is well settled 1F to P. HS 250-300 cm near the continental divide.
Few natural wind slabs to size 2.5 were observed on SW-SE facing slopes through the weekend. As always keep those Mountain Information Network observations coming.
