An atmospheric river storm pumped drenching rains into the heart of California on Thursday as blizzard conditions buried the Sierra Nevada in snow. (Andy Richard/Caltrans District 9 via AP)LOS ANGELES – Evacuations were ordered Thursday in wildfire burn areas prone to mudslides as an atmospheric river storm pumped drenching rain into Southern California while blizzard conditions buried the Sierra Nevada in snow. The system then dropped into Southern California, bringing threats of flash floods and debris flows to areas scorched by recent blazes. Scenic Highway 1 was closed near Big Sur after a section of the roadway collapsed when the cliffside below gave way amid torrential rain. The atmospheric river is part of a major change in weather for California, which had significant drought conditions for months.

An atmospheric river is a narrow flowing column of moisture responsible for producing significant rain and/or snow. These are most common along the West Coast of the U.S. with developing Pacific storms.

The parts of California and Nevada where the wildfires flared are experiencing drought.

TONOPAH, Nev. – The cracked main highway between Las Vegas and Reno reopened Friday, 10 hours after a predawn magnitude 6.5 earthquake that a researcher called the largest to strike the remote area of western Nevada in 65 years. Nevada Highway Patrol photos showed cracks on U.S. 95 before crews repaired them about 35 miles (56 kilometers) west of Tonopah. The vast open range east of the snow-capped Sierra Nevada is seismically active, said Graham Kent, director of the Nevada Seismological Lab at the University of Nevada, Reno. The U.S. Geological Survey reported Friday's temblor struck just east of the Sierra Nevada. “”However, we have learned that other than obvious earthquake damage some damage is discovered later."
