CNN —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. The weather service has warned of “high to extreme” avalanche danger through Sunday afternoon in the Central Sierra and Greater Lake Tahoe area. “Expect snowy conditions throughout the park,” park officials said. A blizzard warning remains in effect for the park area until 7 p.m. on Sunday, according to the National Weather Service in Hanford, California.
