  • Backcountry Avalanche Warning
    The Sierra Avalanche Center in Truckee has issued a Backcountry
    Avalanche Warning for the following areas:
    Greater Lake Tahoe
    * Timing...In effect from Thu 07:00 PDT to Fri 07:00 PDT.
    * Affected Area...Central Sierra Nevada mountains between Yuba
    Pass (Highway 49) on the north and Ebbetts Pass (Highway 4) on
    the south, including the Greater Lake Tahoe area. This warning
    applies only to backcountry areas outside of established ski
    area boundaries and highway corridors where avalanche mitigation
    programs exist.
    * Avalanche Danger...HIGH avalanche danger (4 out of 5) will
    exist in the warning area.
    * Reason/Impacts...A complex mix of heavy snow and rain, strong
    winds, and intense precipitation rates has created unstable
    avalanche conditions. Expect widespread avalanches both above
    and below treeline.
    * Precautionary / Preparedness actions...Very dangerous avalanche
    conditions exist. Travel in, near, or below avalanche terrain
    is not recommended. Natural avalanches are likely and human-
    triggered avalanches are very likely. Large destructive
    avalanches may occur and could run long distances.
