"California Braces for Life-Threatening Blizzard with Up to 12 Feet of Snow"

An extremely-dangerous winter storm has hit California, bringing feet of snow, powerful winds, and rare blizzard conditions, with snowfall rates reaching extreme levels of 3 to 5 inches an hour. The storm is expected to bury parts of the Sierra Nevada under 6 to 10 feet of snow in just a matter of two to three days, posing significant danger to travelers and prompting warnings of "high chance of substantial, long-lasting disruptions to daily life." The snowpack deficit in the Sierra is expected to be erased or exceeded, providing a significant boost to the state's water supply.
