TRUCKEE -- The U.S. Forest Service’s Sierra Avalanche Center is warning of high avalanche danger today through 7 a.m. Friday.
The urgent warning is for backcountry areas in the Sierra Nevada between Yuba Pass on the north and Ebbetts Pass on the south. It does not apply within established ski-area boundaries.
Travel in or below avalanche terrain should be avoided, according to the avalanche center warning.
The highest danger exists on northwest, north and northeast slopes steeper than 30 degrees at and below treeline. Natural and human-triggered avalanches are very likely on these slopes because of new heavy snow slabs sitting on top of weak layers.
There is also considerable avalanche danger at and above treeline due to newly formed wind slabs on slopes 35 degrees and steeper.
