The following message is transmitted at the request of the U.S.
Forest Service Sierra Avalanche Center.

The Sierra Avalanche Center in Truckee has issued a BACKCOUNTRY
AVALANCHE WARNING for the following areas:

NWS Reno NV - NVZ002 (Greater Lake Tahoe)...CAZ072 (Greater Lake
Tahoe (CA))

* WHAT...HIGH avalanche danger exists in the backcountry. Large
avalanches are expected across backcountry terrain.

* WHERE...Central Sierra Nevada Mountains between Yuba Pass (Hwy
49) on the north and Ebbetts Pass (Hwy 4) on the south,
including the greater Lake Tahoe area. This does not include ski
areas or highways where avalanche mitigation programs exist.

* WHEN...In effect until Friday 5 AM PST.

* IMPACTS...Rapidly accumulating snowfall, weak layers in the
existing snowpack, and gale-force winds that blow and drift
snow have created dangerous avalanche conditions in the
mountains. Natural avalanches are likely, and human-triggered
avalanches large enough to bury or injure people are very
likely.

* PRECAUTIONARY / PREPAREDNESS ACTIONS...Traveling in, near, or
below backcountry avalanche terrain is not recommended during
HIGH avalanche danger.

Consult https://www.sierraavalanchecenter.org/ or
