This avalanche advisory is provided through a partnership between the Tahoe National Forest and the Sierra Avalanche Center. This advisory covers the Central Sierra Nevada Mountains between Yuba Pass on the north and Ebbetts Pass on the south. Click here for a map of the forecast area. This advisory applies only to backcountry areas outside established ski area boundaries. This advisory describes general avalanche conditions and local variations always occur. This advisory expires 24 hours after the posted time unless otherwise noted. The information in this advisory is provided by the USDA Forest Service who is solely responsible for its content.

Early spring conditions continue as high pressure dominates the weather pattern. An air temperature inversion is once again in place with the coldest air below about 7,000' this morning. Above 7,000', remote sensors are reporting 6 am air temperatures in the mid 30s to low 40s deg. F. Below about 7,000', air temperatures are in the teens to low 30s deg. F.

Observations from around the forecast area continue to indicate a stable snowpack. Southerly aspects hold thin to very thin snow cover while northerly aspects have a snowpack generally 3 to 6 feet deep in near and above treeline areas. Snow surface conditions are mixed and variable. Expect melt-freeze snow in sun exposed areas and either supportable or breakable crust in other areas. Surface snow that melted yesterday is expected to have refrozen overnight due to radiational cooling, despite above freezing air temperatures in many locations.

Melting of surface snow will occur in most sun exposed areas. Once areas transition from sun to shade, expect the snow surface to begin to refreeze. It is still January and the sun angle remains low, even though air temperatures are warm. Significant areas of wet snow instability are not expected today.

The bottom line:

Avalanche danger is LOW for all elevations and aspects. Normal caution is advised.
