Just a heads up. 

A storm is currently hitting Lake Tahoe and we’ve already got an avalanche in the Hourglass on Tamarack Peak in the Mt. Rose, NV area.

Avalanche Report:

by Sierra Avalanche Center

We dug a pit on a slightly different aspect at direct north to find a 75-85cm snowpack. Our test results revealed a ct4 sc at 10cm/75cm and a ct12 sc at 14cm/85cm and failing on 1-2mm facets close to the ground. As we stepped around the corner we found an r2d2 avalanche with a large 2-2.5ft crown about 100ft wide through the left side of the chute running though a small gulley into the trees below. The crown also ran 100ft down the left flank about 1.5-2ft in depth. Failure layer was 2mm basal facets similar to those seen in the snowpit. It is unknown what triggered it as we noticed it about halfway down the path.  The debris was 3-4 feet deep. We estimated the time of the avalanche based on the new snow on the debris to be sometime between 10-11am. We traversed over and did a quick beacon search on the path with no signals. No other avalanches noted. Sorry I have no pictures. I forgot my phone in the car.
