Powerful California blizzard shuts down roads and ski resorts

 Blizzard conditions continued to slam Northern California over the weekend with damaging winds and heavy snow dumping on mountain ridges down to the valleys.

The most extreme conditions are unfolding at the highest elevations in the mountains, with whiteout conditions and hurricane-force winds.

Winter storm alerts remain across most western states, with blizzard warnings still in effect for the the northern and central Sierra Nevada until Monday morning, where up to 1 foot of snowfall and gusts of 45-75 mph are possible. Gusts across the Sierra Nevada peaks could still reach up to 90 mph.
