Multiple feet of snow are likely for higher elevations in the
West, especially above 5000 ft, including the Sierra Nevada Passes
(including I-80). Extremely heavy snowfall rates surpassing 3
inches an hour combined with very strong winds will result in
impossible travel conditions in the Sierra Nevada. By the end of
the event, 5-12 FEET of snow can be expected along the crest of
the Sierra Nevada. Further east, widespread damaging wind gusts
possibly in excess of 75 mph can be expected across the
Intermountain West. These winds will likely down trees and power
lines, resulting in widespread power outages. Moreover, cooler
temperatures will usher into the West behind the initial front,
lowering the snow levels down into many valleys.

The next Storm Summary will be issued by the Weather Prediction
Center at 700 AM PST. Please refer to your local National Weather
Service office for additional information on this event.
