Transcript for Dangerous trio of storms slam millions across the country
going to begin with that trio of dangerous storms slamming millions all across the country. Overnight new reports from that powerful tornado destroying home after home there in Alabama. Rob in for ginger has the very latest for us, good morning, rob. Hey, good morning, robin. So much of the country being slammed by storms right now. One of three beginning to wind down here in the northeast. But certainly enough snow covering the ground not just here but all the way to California to make any sort of travel extremely difficult. Overnight a triple threat, dangerous storms slamming millions from coast to coast. Slick, dangerous road conditions from New York through new England, drivers underestimating the conditions. This pickup sliding then rolling over. At least six taken to the hospital in Colorado. Icy conditions there leading to this pileup north of Denver. More than 17 cars and she semis involved. Stopping traffic for hours. And near flagstaff, Arizona, a tractor trailer pileup. You can see the one cab sliced red transmission fluid covering the ground. Truckers at a standstill for hours as crews to clean up the wreckage. In Utah several people injured after this crash sent two vehicles flying down an embankment Monday. Chicago getting nearly six inches of snow, plows working through the night to keep runways clear at o'hare and in Alabama new images showing just how badly that ef-3 tornado ripped apart fultondale Monday night. Winds up to 150 miles per hour snapping trees like twigs. Neighborhoods near Birmingham leveled now unrecognizable. I had five minutes to get in that tub and then, poof. Reporter: At least 30 people injured. A 14-year-old boy sheltering in a basement with his family did not survive. Come on, buddy. Reporter: This dog pulled from a pile of wreckage where he was trapped now reunited with its family. Such a tough scene in Alabama. Just goes to show you these winter storms can be so dynamic, not just ice and snow but across the south we always have that severe weather threat. Not so much today. We are focusing now on the dynamic storm coming into look at the winds that took down this tree north of San Francisco. We had 50, 60-mile-an-hour winds there in the bay area and the winds blowing the snow along I-5 near mount Shasta. Blizzard condition, snow piling up like 30 inches in just 12 hours thanks to this atmospheric river. High wind warnings as well from northern California to southern California and we are going to see massive amounts of rain that could easily trigger flash flooding and mudslides over the next several day, robin. Thank you, rob.
