Snowpack Summary and General Conditions
Matt Cozart was out and about on Monday
and reported rain up to 9,000 ft. He also reported 8 inches of dense snow and good skiing in the higher elevations. It seems the rain on snow has consolidated the snowpack, and any weaknesses associated with rain should be locked up at this point.
The avalanche danger will be on the rise today. The mountains could pick up 8 inches during the day, and maybe a foot by the time it's all said and done. Strong winds will create unstable slabs of wind drifted snow at mid and upper elevation bands. Instabilities could develop in the new snow during times of heaviest snowfall, especially if the mountains receive a foot of snow. Use small, steep test slopes to see how the new snow is reacting. Weak interfaces exist on some slopes with a Northerly component to their aspect. These slopes should be avoided during this storm. Let's give it some time and see how these slopes react to this loading event.
Springtime in the mountains means that things can change quickly and there can be an assortment of avalanche problems within an hour or an aspect of one another. It is a good time to year to be willing to adapt and change your plan if the weather or snow conditions change.
