The weak layers of sugary faceted snow at the base of the snowpack remain a concern. We are now adding stress to those layers again with the new snow that is accumulating. We are adding the snow slowly so it's tricky to say when things will become really dangerous. The wind has been fairly light which is a good thing in that it is not rapidly loading slopes with snow.

The bottom line is you can't mess around with a known buried Persistent Weak Layer of faceted snow. This stuff will bite you when you're not expecting it.

Snow and Weather

Current Conditions: Another 2 to 4 inches of snow accumulated overnight. This brings totals up to 5 to 7 inches since Tuesday. The wind really slowed overnight and is basically calm. Temepratures are in the upper teens.

Mountain Weather: The large closed low pressure system is still working its way south over California and will start to move east through Arizona tomorrow. This system will continue to give us periods of snow through Saturday. For today, expect snow with another 3 to 6 inches possible by Friday morning. Temperatures will be around 20˚F today with light southerly wind. Another period of snow looks like it should occur Friday afternoon then another one early Saturday morning with lingering light snow through Saturday.
