After a beautiful sunny day in the mountains clouds moved back into the area overnight. There is a chance of snow today and increased easterly winds but this should not have much impact on avalanche hazard. Watch for changing conditions if more snow falls than forecasted.
Today will be another day of Normal Caution (LOW danger). Things to keep in mind if you are headed into the backcountry:
In anticipation of snow, we have been closely mapping the surface conditions as well as watching for new surface hoar growth. Surface hoar has been observed from valley bottoms to the Alpine and is resting on a variety of surfaces. There is a stout sun crust on southerly facing slopes. On shaded aspects 4-8″ or so of soft near surface facets sit over a firmer base and sastrugi, wind crust and/or rime crust can be found along ridgelines. The question is will it snow just enough today to bury the surface hoar and will we call it the “Fat Tuesday/Mardi Gras” weak layer? Hopefully some surface hoar will be knocked over by the wind!

Sun crust with surface hoar and stellars (from Sunday), Twin Peaks, 3-4-19.
Yesterday: Partly cloudy skies becoming mostly sunny. There was some valley fog in the morning. Winds were light and temperatures were in the teens to 20Fs at upper elevations and in the 30Fs at sea level. Overnight clouds moved in and winds picked up slightly. Temperatures were in the teens to 20Fs.
Today: Mostly cloudy skies with a chance of snow showers. Winds will be southeasterly 5-15 mph with gusts into the 20s. Temperatures will be in the 20Fs. Overnight looks to be similar with winds becoming calm.
Tomorrow: Continued cloudy skies with a chance of snow, calm winds and temperatures in the 20Fs. A more promising storm still looks to be on track for the weekend.
