Avalanche Advisory published on February 9, 2017 @ 7:00 am
This advisory is valid for 24 hours
Issued by Andy Anderson - Tahoe National Forest
The avalanche danger will rise to CONSIDERABLE today at all elevations as hurricane force winds and heavy precipitation impact the region. Human triggered wind slab avalanches and wet loose avalanches will become likely today. As snow levels lower this afternoon and evening, wind slabs will become more widespread and larger and loose wet snow instabilities will become smaller and more isolated. Natural avalanches will become possible this afternoon and during the night as more snow accumulates.
Another storm has arrived over the region with hurricane force southwest winds along the Sierra Crest. The winds will become stronger and more widespread today as this storm builds. Even winds at lower elevations could reach into the 40 to 60 mph range with gusts to 100 mph. At the upper elevations expect to see sustained wind speeds in the 60 to 80 mph range with gusts to145 mph. Winds should start to decrease some after midnight and into tomorrow. Rain and snow will increase over the region today with periods of heavy precipitation from midday onward. Most of today's precipitation should fall as 1 to 2 inches of rain below 8000 ft. due to snow levels that remain between 8000 and 8500 ft. for much of the day. Temperatures should start to cool this afternoon and evening and the forecast calls for snow levels to drop to around 7000 ft. tonight allowing for 6 to 12 inches of snow to accumulate. By tomorrow this storm should start to wind down and colder air should push into the region. Expect another 3 to 6 inches of snow tomorrow with snow levels at or below Lake Level.
