California prepares for yet another winter storm fueled by atmospheric river.

Twin storms are expected to hit California this week, with the second one likely to bring an atmospheric river that could exacerbate river flooding concerns in Northern California. The storms have already caused flooding, collapsed roofs, and power outages, but have also helped pull most of the state out of a three-year drought. Meanwhile, Michigan experienced a whiteout that caused scores of cars to crash on Interstate 96. The Deep South is also experiencing record-breaking cold temperatures until Tuesday.
